GMF508-C 4-20mA high precision stainless steel natural gas hydrogen gas nitrogen gas turbine flow meter
Product Overview
GMF508-C Gas turbine flowmeter is learned the flow meter at home and abroad advanced technology optimized design, integrated the theory of gas mechanics, fluid mechanics, electromagnetism and developed a new generation of high precision, high reliability of gas precision measuring instrument, has a good performance of low pressure and high-pressure measurement, multiple way signal output and low sensitivity to the fluid disturbance, is widely used in natural gas, coal gas, liquefied gas, and light hydrocarbon gas and gas metering.
GMF508-C Gas turbine meter adopts advanced ultra-low power single-chip microcomputer technology of turbine flow sensor and display the integration of integrating new intelligent instrument, adopts double row at the scene of the liquid crystal display, with compact bodies, intuitive and clear reading, high reliability, without external power supply interference, lightning resistance, low cost, obvious advantages. The instrument is equipped with six-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on-site. High-resolution LCD displays both instantaneous flow (4 significant digits) and cumulative flow (8 significant digits with zero clearing function). All valid data will not be lost for 10 years after power loss. Gas turbine flowmeters are explosion-proof products, explosion-proof grade: ExdIIBT6.
