Piston Type Circulating Real Gas Flow Standard Device use real gas to detect G1.6~G6 ultrasonic and thermal gas meters.
In order to provide flow meter manufacturers with in-depth research on the measurement characteristics of gas flow meters for different measured media such as air and gas,our company proposed a method based on the principle of conservation of mass, which uses standard gas to compare air to explore thermal and ultrasonic gas. Represents a new method of value error testing. Research on air calibration and actual gas error testing and correction for G1.6~G6 ultrasonic and thermal gas meters. The nominal volume of the piston standard device is 120 L, the maximum working pressure is 10 kPa, and the cylinder volume standard uncertainty Urel=0.05% (k=2), which meets the flow range of (0.016～10) m³/h for different media of electronic gas meters The test requirements for the error of the value shown below. The actual flow device is one of the important test devices indispensable for gas instrument manufacturers to effectively improve product performance.
