'''Filling Scales''' are used to increase the level of accuracy obtained in a container.

[[Containers]] are often filled by weight. These can include [[Drums]], cylinders,[[Tanks]],pails,[[Cartons]],totes, and almost any other type of box. While it may be more convenient to fill by volume, there are a number of parameters that can affect the accuracy. Depending on the type of material being filled, it may compact differently depending on the temperature or the relative humidity. The particles may cling to each other by static electricity. The filling force may push the material together, or may allow it to incorporate air. The density of the material may differ. Therefore, filling scales may be needed to increase the level of accuracy obtained. The weight can be independently determined by use of the scale, which will generally be underneath the item being filled. Of course it is important to de-couple the filling tube or hose from the container, so that it does not affect the reading. It may also be useful to control the rate of filling. A rapid feed rate may apply a downward force into the container, and onto the scale, also causing errors. It is very useful for filling scales to include setpoints for control purposes.

Generally set by the operator, a setpoint may give a visual and electrical signal that can be used to automatically turn off the feeding device, which may be a pump, augur, conveyor or similar. A second setpoint will often be set somewhat lower than the first, and may be used to slow down the rate of feed. This will provide enhanced accuracy. Scales used for this purpose should be quite rugged, to accommodate the high forces that may be applied when the full container is removed from the scale platform. Stainless steel load cells are the best choice for this purpose. It is also convenient to use a scale with a low platform height to provide easy access for loading and unloading.

Whenever there is an explosive environment, there is a need for an '''Explosion Proof Scale'''.When there's oxygen or air, explosive matter and explosion leading source, such as electronic light, flaming surface, the explosion will happen. The explosion proof scale must control at least one of these matters to achieve the aim of anti-explosion. This is the triangle principle of the explosion.

Industrial explosion proof scales have a number of important characteristics. The most important is the FM rating that is required for your hazardous area. Others include the platform size and capacity, accuracy, durability and cost. Generally, any of the first four may be improved, but only be increasing the cost. By a combination of excellent engineering, efficient manufacturing made in the USA, and a unique sales channel that eliminates a middle tier.

[[File:Electronic scales.jpg|thumb|right|Electronic Scales]]
'''Electronic Scale''' is an electronic measuring device that uses fiber optics to detect and transmit its position to a digital or computer readout for display.

Instead of glass, a printed circuit on a stainless steel ruler is used to trigger at least two microelectronic hall effect [[Sensors]]. Resolution is limited to 0.01mm but shielding from coolant and flying chip is not a requirement. These scales are very resistant to everyday shop contaminants and debris. Electronic scales are much cheaper than their glass counterparts.

Electronic scales are available with built-in displays so they can be used independently.
It will calculate weight in grams, onces and pounds depending on the settings. They come in various sizes depending on what your weighting.
==How do electronic scales work?==
Electronic Scales work with the use of a strain gauge load cell. Whereas analog scales use springs to indicate the weight of an object, electronic scales convert the force of a weight to an electric signal. Its key components consist of a strain gauge, a device used to measure the strain of an object, and load cell sensor, an electronic device used to convert a force into an electrical signal. A load cell is also known as a force transducer.

[[File:Conveyor scales.jpg|thumb|right|Conveyor Belt Scales]]
'''Conveyor Belt Scale''' or belt weigher is a piece of industrial control equipment used to gauge the mass or flow rate of material travelling over a troughed conveyor belt of any length which is able to adequately contain the material being weighed. These are also known as [[Belt Scales]], dynamic scales, conveyor scales, and in-motion weighers. Many such [[Check Weighers]] or [[Feed Weighers]] are an active part of the process flow control of the conveyor line.

A conveyor belt scale replaces a short section of the support mechanism of the belt, which might be one or more sets of idler rollers, or a short section of channel or plate. This weighed support is mounted on load cells, either pivoted, counterbalanced or not, or fully suspended. The mass measured by the load cells is integrated with the belt speed to compute the mass of material moving on the belt, after allowing for the mass of the belt itself.

Conveyor belt scales generally include the necessary electronics to perform this calculation, often in the form of a small industrialized microprocessor system. A conveyor belt scale is normally mounted in a well supported straight section of belt, with no vertical or sideways curvature, and as close to level as is practicable. The weighed support must be aligned vertically and horizontally with the adjacent supports to avoid tensile forces in the belt skewing the measurement. Due the belt tension variation, frequent check calibration must be done.
Outputs from conveyor belt scales are typically:
* pulses at predefined increments of mass
* an analogue signal proportional to the flow rate

In addition, some belt weigher controllers will offer features such as driving an output to stop the belt when a predefined mass of material has been measured, or a range of alarms to indicate nil flow, belt slippage and belt stoppage.Uses include mineral and aggregate extraction, continuous mixing processes, control of variable rate feeders, port handling and ship loading processes.

'''Beam Scale''' is a portable balance consisting of a pivoted bar with arms of unequal length.A beam scale is a type of scale commonly used in the laboratory to determine the mass of samples. To use the scale, you use sliding weights called riders on three beams, each with progressively small incremental amounts.

Familar versions of the concept are seen in sliding bar postal scales, and in the older scales used in doctors' offices .The larger increments may be 100 grams and 10 grams, and the final beam will display in grams and decimal fractions of a gram. Medical beam scales are strong and durable fitness scales built to last you a long time. Mechanical beam scales are used in hospitals, offices,gyms,schools,or even in homes.

[[File:Analysis Scales.jpg|thumb|right|Analysis Scales]]
'''Analysis Scale''' is an instrument resembling a bathroom scale that estimates the percentage of fat in the body. It uses a small electrical current that enters the body through bare feet. The body's density is measured by the current, and the body fat percentage is determined based on the body density measurement.Analyzing body fat and body density are more accurate tools in understanding a person's health than weight alone. This is because fat weighs less than muscle and bone, so it's possible for a person with a high percentage of body fat to weigh less than someone with a high percentage of muscle. In the past, it was not possible to accurately measure body fat percentages with a home device. One common method involved weighing a person, and then submerging him in a tub of water to be weighed again. The higher a person's body density, the lower that person's fat percentage.

A newer method of measuring body fat is called body impedance analysis. Before the invention of the analysis scale, the procedure was generally done in a clinical setting. The person would lie prone on a cot with electrodes attached to the hands or feet. A 50 kHz current sent through the body measured the density of the tissues by the amount of water contained in them. This method is quite accurate because fat is only 10 percent to 20 percent water while the rest of the body is closer to 70 percent or 80 percent water.

The simplest analysis scale allows the user to enter information such as gender and activity level. A person stands on the scale and the scale measures both weight and impedance of the current as it travels up one leg through the body and down the other leg. A microprocessor uses a formula to give an estimate of body fat. More elaborate analysis scales found in hospitals or health clubs allow a user to enter detailed information such as age and specific fitness level information. These scales can give readouts that include fat weight, body mass index, and hydration levels.
A analysis scale measures body fat accurately to within 5 percent. For home users, the scales are better used to track changes in body fat over time. The conditions for using the scale need to be fairly consistent for the most accuracy. Body temperature and hydration level should be approximately the same for each use, and weighing should take place around the same time of day.

'''Analytical Balance''' is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product.The sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure from causing an error in reading. Single pan mechanical substitution balance maintains consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added.

Electronic analytical scales measure the force needed to counter the mass being measured rather than using actual masses. As such they must have calibration adjustments made to compensate for gravitational differences.They use an electromagnet to generate a force to counter the sample being measured and outputs the result by measuring the force needed to achieve balance. Such measurement device is called electromagnetic force restoration sensor.

'''Balance''' is a measuring instrument for determining the weight or mass of an object. These are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized medical scales and bathroom scales are used to measure the body weight of human beings.
The balance was the first mass measuring instrument invented.In its traditional form, it consists of a pivoted horizontal lever of equal length arms, called the beam, with a weighing pan, also called scale, scalepan, or bason , suspended from each arm . The unknown mass is placed in one pan, and standard masses are added to the other pan until the beam is as close to equilibrium as possible. In precision balances, a slider mass is moved along a graduated scale. The slider position gives a fine correction to the mass value. Although a balance technically compares weights, not masses, the weight of an object is proportional to its mass, and the standard weights used with balances are usually labeled in mass units.

Balances are used for precision mass measurement, because unlike spring scales their accuracy is not affected by differences in the local gravity, which can vary by almost 0.5% at different locations on Earth. A change in the strength of the gravitational field caused by moving the balance will not change the measured mass, because the moments of force on either side of the balance beam are affected equally. In fact, a balance will measure the correct mass even on other planets or moons, or any location that experiences a constant gravity or acceleration.

Very precise measurements are achieved by ensuring that the balance's fulcrum is essentially friction-free , by attaching a pointer to the beam which amplifies any deviation from a balance position; and finally by using the lever principle, which allows fractional masses to be applied by movement of a small mass along the measuring arm of the beam. For greatest accuracy, there needs to be an allowance for the buoyancy in air, whose effect depends on the densities of the masses involved.
The original form of a balance consisted of a beam with a fulcrum at its center. For highest accuracy, the fulcrum would consist of a sharp V-shaped pivot seated in a shallower V-shaped bearing. To determine the mass of the object, a combination of reference masses was hung on one end of the beam while the object of unknown mass was hung on the other end . For high precision work, the center beam balance is still one of the most accurate technologies available, and is commonly used for calibrating test weights.
To reduce the need for large reference masses, an off-center beam can be used. A balance with an off-center beam can be almost as accurate as a scale with a center beam, but the off-center beam requires special reference masses and cannot be intrinsically checked for accuracy by simply swapping the contents of the pans as a center-beam balance can. To reduce the need for small graduated reference masses, a sliding weight called a poise can be installed so that it can be positioned along a calibrated scale. A poise adds further intricacies to the calibration procedure, since the exact mass of the poise must be adjusted to the exact lever ratio of the beam.

[[File:Rotary Scalpel Metering Feeders.jpg|thumb|right|Rotary Scalpel Metering Feeders]]
'''Rotary Scalpel Metering Feeders''' introduces a unique and revolutionary technology to the batching and filling process industries.It is recommended for applications requiring exceptional precision and ultimate process optimization.
==Technology==
Rotary scalpel technology utilizes two innovative key components: a large inlet specially designed to ensure consistent material flow into the rotary feed drum and a pneumatic scalpel. Upon receipt of a set point weight, the pneumatic scalpel will knife off from a filled vane of the rotary feed drum the precise amount of material needed to complete a batch or fill a container.Unneeded material remaining in the same vane is recycled back to the material source, eliminating all waste. Rotary scalpel technology is the only metering technology that delivers a variable but finite volume of material to finalize the batch or fill process. All other solids metering devices take the approach of narrowing the flow channel of inlets, trays,screws, etc. to reduce volume to be delivered. All these restrictions lead to inconsistent flow of the material. Rotary scalpel technology is free of these limitations.
==Features==
* Compact, space efficient design assures ease of installation in new or existing process lines
* Modular construction for flexibility of application
* Simple design for ease of maintenance
* Specialized metering and discharge of material preventing segregation and degradation
* Extremely accurate volumetric delivery device
* Simple mechanical design–only three moving parts ensures reliable, long term operation
* Designed to utilize a material’s ideal flow rate by eliminating inlet or discharge constraints
* Available for volumetric or gravimetric operating modes
