MYHG-67 Liquid Flow Meter Calibration Test Stand

Liquid flow meter calibration experimental bench-yesThe important parameters in production and scientific experiments, whether in industrial production or scientific experiments, require flow measurement to calculate the production capacity of the process or equipment and the proportion of flow in each part, in order to evaluate the process or equipment. At present, instruments for measuring flow can be roughly divided into three categories, namely velocity method, volume method, and mass flow method.
Although various flow meters undergo flow calibration and establish flow scale scales before leaving the factory, the operating conditions such as working medium, pressure, temperature, etc. often differ from the original calibration conditions when applied in the laboratory or production. In order to use the flowmeter accurately, on-site calibration work is required before use.
Liquid flow meter calibration experimental benchThe main method used is the weighing method to calibrate and verify orifice flow meters, electromagnetic flow meters, turbine flow meters, and vortex street flow meters. Using a high-precision data acquisition instrument to collect data and transmitting it to a computer through a serial port for use; Complete real-time data reading, data calculation and storage, historical data query, real-time curve drawing, and achieve flowmeter calibration.
