Turbine Flow Meter/oil meter/gas meter/flowmeter/flow meter
(1) High accuracy (regular accuracy±1%R, ±0.5%R, highest accuracy±0.2% R);
(2) Good repeatability (short-term one reaches 0.05%--0.2%), priority to be used in trade settlement for its extremely high accuracy in the regular calibration or on-line calibration.
(3) Pulse frequency signal output is applicable to totality calculation and computer connection with no zero drift and strong anti-interference capacity.
(4) High frequency (3-4kHz) can be achieved, and has high resolution.
(5) Wide rangeability: medium or large diameter may reach 1:20,and small diameters are 1:10.
(6) Compact and light weight structure, convenient installation and maintenance, extensive application ability.
