(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 range ratio: 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.
(7) Application to high pressure measurement with its unnecessary opening hole to be made into high pressure instruments.
(8) Complete tailored version sensors can be designed to different kinds of types according to users special needs. For instance, low temperature type, high pressure type, sanitary type, etc.
(9) Insertion type can be made, that is applicable to large normal diameters measurement for its little pressure loss, low price, unnecessary stopping flow to take out it, and convenient installation and maintenance. 01
