Design and research of water flow standard facilities based on field service

Abstract

A flow standard facility based on field service is designed to solve the problem of on-site high-precision parameter metering for water flow standard facilities, in which the water is take as the medium, the mass flowmeters are used as the transfer standard of liquid flow, the variable frequency pump and the surge tank are acted as the secondary regulation system, and the hardware and software platform of LabVIEW are conducted as the development system. The entire facility is small and light weight so that it can be carried to the scene for rapid calibration. Because it changes from sent by customers to sending calibration to customers and saves the standby time caused by disassembling and sending flowmeters, it improves the production efficiency of enterprises greatly. Ultimately, the facility can be produced and it will fill the domestic technical gap of water flow calibration based on field service.
