Digital intelligent gas turbine biogas flow meter price
/ Product Description /
LWQ gas turbine flowmeter is a kind of velocity flowmeter which can accurately measure gas flow rate. It has the advantages of simple and lightweight structure, high measurement accuracy, good repeatability, wide measurement range and convenient installation and maintenance. It is widely used in the measurement of various gases such as natural gas, city gas, propane, butane, air and nitrogen in petroleum, chemical industry, metallurgy, aviation, scientific research and other departments and industrial fields. Due to its high accuracy and good repeatability, it is suitable for trade measurement and industrial process detection.
Main features of the product
♦ high precision, good repeatability, small pressure loss and good seismic performance;
♦ Adopt high-quality bearings, with small friction resistance, good sealing performance and long life;
♦ integrating microprocessor, flow sensor, high-precision temperature and pressure sensor, directly measuring the flow, temperature and pressure of the gas to be measured, and automatically performing flow tracking compensation and compression factor correction calculation;
♦ 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.
♦ The power consumption is low and can be supplied by internal battery or external power supply.
♦ It has the function of real-time data storage, which can prevent data loss during battery replacement or sudden power failure, and internal data can be stored permanently in the power failure state.
♦ It can be used with IC card prepayment system to facilitate trade settlement;
♦ The explosion-proof marks of explosion-proof products are EXIBIT 4 and EXIBIT 6
