Gas turbine flowmeter battery power supply

Gas turbine flowmeter battery power supply，When it is inconvenient to supply power from an external power source, battery power is used.

However, when the flowmeter requires flow pulse signal output, an external power supply with a supply voltage of+24VDC is needed.

When the flowmeter requires RS485 data communication, a+24VDC power supply needs to be added.

Gas turbine flowmeter battery power supplyMain features:

1) High precision, good repeatability, low pressure loss, and good seismic performance;

2) Using high-quality bearings, with low friction resistance and good sealing performance, hand name;

3) Integrating microprocessors, flow sensors, high-precision temperature and pressure sensors, directly measuring the flow rate, temperature, and pressure of the measured gas, and automatically performing flow tracking compensation and compression factor correction calculations;

4) The instrument has pulse signal and analog signal output, and can directly achieve centralized data collection and real-time management of computer data through RS485 communication interface or GPRS system;

5) Low power consumption, can be powered by internal batteries or external power sources;

6) Equipped with real-time data storage function, it can prevent data loss during battery replacement or sudden power failure. In the event of a power outage, internal data can be saved;

7) Can be used in conjunction with IC card prepaid system for easy trade settlement;

8) Explosion proof products have explosion-proof markings ExibIIBT4 and ExibIIBT6.
