The design of the initial weighing systems based entirely on the work of Archimedes and Leonardo Da Vinci. Here we use the position of calibrated counterweights on a mechanical lever to the balance and determine the mass of unknown weights. The variation in this device uses several mechanisms, each difference long and balanced with a single standard of weight. Later, calibrated springs replaced these weights, and development in manufacturing and resources at these scales accurate and reliable.
However, the introduction of electronic (usually strain gage-based) load cells was the first design change key in weighing technology. Today's processing plants are preferred electronic load cells in most applications, although escalators used if the operation is manual and staff prefer to work and safeguard the facility.

Lever scales are used for the number of applications and balances for vehicles, hopper scales, tank scales, railroad track scales, platform scales and crane scales. The duration of the changes that due to the gradual change of temperature can be corrected only by manual adjustment or by applying correction factors. Reward for rapid temperature changes or irregular is more difficult, and often can not be corrected. Since the accuracy and consistency of well maintained and calibrated mechanical scales are used as standards for trade and is satisfactory to the government authorities. Spring balances are also simple, and, if it is made of high quality alloys (having a modulus of elasticity unaffected by temperature variation) can be very accurate if properly maintained. They are reasonably priced and is best suitable for light loads.

The effects of any weighing system is to acquire information on net gross mass or weight, or a combination thereof. To obtain the net weight of the contents of a vessel you need two measures: the total weight and the weight of the container without charge. Net weight is obtained by subtracting from each other. Whereas the brunt of involvement despite large quantities. Weight total is often obtained by making incremental measurement and the sum of these weights to achieve the total. This allows a reduction in the size of the weighing system, which reduces accuracy and rising costs. Belts can also be used for production by weight. But this is a less accurate method, which total weight is achieved in bulk by integrating the product of the speed of the belt and the belt load on one phase of time. Lots of weight systems meet the needs of industrial recipes by the proper dispensation of a number of materials in general container for receiving feedback.

The performance of a weighing system is affected by many factors as temperature, vibration, environment, structural movement and maintenance. Temperature compensation is generally provided by most systems and its range should be above the expected range of variation of operating temperature. If the process vessel is hot or cold, tank-to-cell heat insulation pads can be provided. Temperature adjustment from zero and built in a number of high-quality circuits cell strain gauge load. pulse influences can be minimized by splitting the support of the weighing system of structures or solid bases of support engines or other tools such vibration or are affected by nearby vehicular traffic
