Industrial diaphragm gas meter
Product overview
The industrial diaphragm gas meter is suitable for measuring the gas flow rate of natural gas, coal gas and liquefied petroleum gas. The series of gas meters is composed of three parts of the housing, the machine core and the counter. The meter has high sensitivity, accurate measurement, convenient maintenance and easy maintenance, and can prevent counter reversing by anti-reverse device. With special surface treatment technology, it has strong anticorrosive capability and long service life.
 
Main advantages
1. It can achieve prepaid management by IC card. One gas meter one card with different user passwords, safe and reliable.
2. The surface of the metering chamber housing is treated with anticorrosion and has excellent corrosion resistance.
3. The controller has the function of detecting the battery quantity, and realizes the intelligent control to the power supply management. Whether the external electricity or the internal electricity is replaced, the controller can give the user enough time to change, and it does not affect the normal use.
4. The upper and lower housing is sealed by gasket and fastened by screw, which ensures sealing, easy to disassemble and assemble, and maintenance.
5. Key to view the remaining and cumulative gas consumption.
6. Extensible IC card gas meter.
7. the function of expanding IC card
