Sonic nozzle gas meter test bench is used to test domestic gas meter and industrial gas meter from G1.6 to G4.0, G6.to G40,with flow rate from 0.016m³/h to 6.0m³/h,0.06m³/h to 65m³/h.
Gas meter type:Ultrasonic gas meter/diaphragm gas meter
The GNP-type Image-Based Sonic Nozzle Method Gas Meter Error Calibration Device is a new generation developed by TNMA,Sonic Nozzles are internationally recognized as the best Flow Transfer Standard for gas flow measurement and Calibration.This device adopt venturi sonic nozzle as the master meter.The perfect test bench is widely used in gas meter factories in Chinese market and warmly welcomed in the worldwide market.
Which has the features of fully automated, high-precision, efficient, and highly reliable.
The device primarily consists of a sonic nozzle, dynamic image capture system, multi-station gas meter calibration workstation, oil-free vacuum pump, control air path, microcontroller system, and PC. Using the sonic nozzle as the primary standard, it automatically selects nozzle combinations based on different flow points of the gas meter. Utilizing microcontroller and high-precision A/D conversion technology, it automatically detects parameters such as temperature, pressure, humidity, and participates in real-time error correction calculations to ensure device accuracy. The entire system achieves fully automated testing under PC control and incorporates comprehensive functions such as raw data storage, querying, and printing.
The device uses Venturi sonic nozzles as standard instruments. The computer automatically selects the optimal nozzle combination based on the different flow points of the flow meter being tested.
Multiple gas meters can be connected in series for testing, significantly improving testing efficiency. By switching valves, the device can automatically select the left or right entrance of the gas meter for calibration.
Through dynamic image processing, the device can quickly, accurately, and reliably capture gas meter reading signals.
