详细介绍

BTLWGQ series gas turbine flowmeter is my company to sum up the experiences of many years of development, and USES a number of innovative technologies and successful development of a new generation of products, product directly measuring the working condition of the gas flow rate and total volume, can be configured volume correction instrument, measuring the temperature, pressure, the conditions of the gas volume flow rate and total amount, is the city gas trade measurement and gas metering and testing High performance meter.

product features

Integrated with microprocessor, temperature sensor and pressure sensor, it directly measures the flow rate, temperature and pressure of the measured medium, and automatically compensates the temperature and pressure of the flow and corrects the compression factor.

Low power consumption design, can be powered by lithium battery, the battery can be used for more than 2 years; It can also be connected to external power supply.

The instrument has pulse signal output, 4-20mA analog signal output, RS485(Modbus-RTU protocol) communication output; At the same time there is IC card signal output, can be used with IC card prepaid system, easy to trade settlement.

Special LCD screen (with backlight), intuitive and convenient reading, can simultaneously display the instantaneous flow of standard condition, the instantaneous flow of working condition, the cumulative flow of standard condition and the temperature, pressure and other parameters of the measurement medium.

With real-time data storage function, it can prevent the data loss when the instrument suddenly power off. In the state of power failure, the internal data can be saved permanently.

Reliable electromagnetic compatibility design, good anti-interference performance, high reliability, meet the electromagnetic compatibility test requirements of JJG1037-2008 standard.
