Nanjing Hanhua Fluid Technology Co., Ltd

Gas turbine flow meter.

Brand: Hanhua.

Series: NCF-GTM Series.

Product introduction:
The NCF-GTM gas turbine flow meter is a speed flow meter that measures momentum and accumulation based on the principle of momentum moment conservation. It has the advantages of high precision, good repeatability, simple structure, wide measuring range, small size, light weight, small pressure loss and convenient maintenance. Can be widely used in petroleum, chemical, metallurgy, urban gas pipe network and other industries. Especially in urban gas metering, pipeline network metering and gas regulatory station metering has been widely used.
Characteristics:
(1) the measuring range is wide, the lower flow rate is less than 0.5m/s, the pressure loss is small, and the impant wheel has strong impact resistance;
(2) with high anti-electromagnetic interference and anti-seismic ability, the use of fully sealed isolation to protect self-lubricated bearings and oil storage pots, reliable performance and long working life;
(3) The use of advanced ultra-low-power single-chip microcomputer technology, the whole machine function is strong, low power consumption, superior performance, with nonlinear accuracy compensation function of intelligent flow display. The accuracy of the correction formula is ± 0.02%.
(4) The meter coefficient can be set online by the keystrokes and can be displayed on the LCD screen. LCD screen intuitive and clear, high reliability;
(5) Pressure compensation can be made in the stable state of the gas pressure under test.
