 Water Meter Testing Device


Overview

Most of the traditional liquid flow standard devices are based on the mass method and the volume method. The generation of the flow source relies on the water pump to provide the flow, but the flow is pulsating, the flow stability is poor, and the flow point adjustment is not accurate. With the rapid development of these devices, these devices can no longer meet the requirements.


In order to meet the requirements of liquid flowmeter verification, calibration, factory inspection and the growing trend of new flowmeter production, our company has designed and manufactured an active piston liquid flow standard device with water as the medium. The standard device has a unique design and its basic working principle It is to compare the volume flow of the fluid discharged by the piston with the volume flow of the flowmeter under test in a certain time interval. The volume of the fluid discharged by the piston is obtained by the product of the cross-sectional area of the piston cylinder and the displacement of the piston.


Driven by the servo motor to reduce the disturbance to the liquid flow, it has many advantages such as stability and reliability, good repeatability, high degree of automation, and easy operation, avoiding the shortcomings of the start-stop effect or the commutator effect of the traditional liquid flow standard device. It is beneficial to improve the measurement uncertainty level.


The device also has the characteristics of self-contained, compact structure, high efficiency and energy saving, no need to build a pool, no need to put forward special structural requirements for buildings, and is very suitable for production testing and product development testing of small flow metering instruments.
