Shanghai Yokogawa Electric Co., Ltd.

Project name: Standard meter method for automatic verification of positive pressure gas rotor flowmeter

The main technical parameters: Device expansion uncertainty: 1% (standard table uncertainty 0.5%) (K = 2)

Test pipeline range: DN15 ~ DN80

Flow range: air 1-200Nm3 / h

Project description: This project is a set of standard meter method gas rotor flowmeter automatic verification device constructed by Shanghai Yokogawa Electric Co., Ltd.
. The whole structure adopts skid-mounted structure design. The gas source uses a compressor and enters the test tube section through the gas storage tank and the pressure stabilization container. And use microcomputer
The dynamic verification control system can carry out the verification of the gas rotor flowmeter below 1.5%. Bell calibration gas is also provided for calibration of standard flow meters
The body flow standard device can calibrate or verify the standard flow meter at any time or periodically.
