What Is A Volumetric Water Flow Standard Device?

As people have higher and higher requirements for product quality, process control, production process, and cost control, more and more flowmeter products with high precision and high performance have entered various fields. In order to ensure the accuracy of high-precision flowmeter products, the measurement work of manufacturers needs higher requirements. Establishing a flow standard device with high precision, high reliability, and high efficiency is still an important part of the measurement work.
Volumetric and gravimetric flow calibration devices have been used for a long time because they are easy to trace and the reference is easy to obtain, and they are widely used in enterprises and laboratories. However, this type of system has disadvantages such as low efficiency, long measurement time, difficult maintenance, easy interference, narrow application range, and high cost. With the increase in pipeline size, the investment and system size has doubled, and it has become increasingly difficult for flowmeter manufacturers or laboratories with heavy testing tasks to meet their needs.
The volumetric water flow standard device is mainly composed of a liquid source, test pipeline, standard liquid flow meter, timer, and control equipment. The requirements for the pipeline design, control system, and pressure stabilization measures of the standard meter method liquid flow standard device are the same as those of the static volume method liquid flow standard device.
The liquid flow standard device can give the standard flow according to the verification flow point, and can also give the standard flow according to the verification flow range. Standard liquid flowmeters can be connected in series with the test pipeline alone, or multiple units can be connected in parallel and then connected in series with the test pipeline. Standard liquid flow meters can be various liquid flow meters. The standard table method has wide adaptability, strong anti-interference ability, high efficiency, and high reliability, and has been recognized by more and more enterprises and laboratories.
