LWGQ gas turbine flowmeter is a kind of velocity flow meter that accurately measures gas flow. It has the advantages of simple and light structure, high measurement accuracy, good repeatability, wide measurement range, convenient installation and maintenance, etc. It is widely used in the measurement of various gases such as natural gas, city gas, propane, butane, air, nitrogen and other gases in petroleum, chemical industry, metallurgy, aviation, scientific research and other departments and industrial fields. Due to its high precision and good repeatability, the instrument is suitable for trade measurement and industrial process detection.
l High precision, good repeatability, small pressure loss and good seismic performance;
l Use high-quality bearings, with small friction resistance, good sealing performance and hand name;
l Integrating a microprocessor, a flow sensor, a high-precision temperature sensor and a pressure sensor, directly measuring the flow rate, the temperature and the pressure of the measured gas, and automatically performing flow tracking compensation and compression factor correction operation;
l The instrument has pulse signal and analog signal output, and can directly realize centralized collection and real-time management of computer data through RS485 communication interface or GPRS system.
l Low power consumption, internal battery power supply or external power supply;
l It has a real-time data storage function, which can prevent data loss during battery replacement or sudden power failure. In the power failure state, internal data can be stored permanently.
l It can be used with IC card prepayment system to facilitate trade settlement.
