Helical gear flow meters are typical volumetric flow measuring instruments which directly measure the quantity of flowing liquid by means of a couple of rotors. It is a kind of positive displacement flow meters, and has features as below:
Large turn down ratio
Small pressure loss
Can measure fluids with max 3500cp viscosity
Can work on high temperature fluids
Easy calibration and easy installation
It can be mechanical type flow meter, or equipped with electronic transmitters and digital display and frequency to current converters are available for remote totalization, recording and presetting of metered volumes.
They may be used for custody transfer purposes, operating controls and for the many other needs of the petroleum, chemical, pharmaceutical industry, etc.
Accuracy level: 0.5%, 0.2%
The temperature of the measured liquid;
With high temperature radiator, max temperature can reach 250 °C
Ambient temperature can be -41 ° C ~ +60 ° C
Repeatability error: the repeatability error of the flowmeter does not exceed 1/3 of the basic error
Flange standard: DIN Standard, JIS standard, ANSI standard.,etc
