■ No movable parts, long-term stability, simple structure for easy installation and maintenance;
The sensor output is a pulse frequency, which is linear with the actual flow rate of the measured fluid. There is no zero drift, and the performance is very stable. The structural forms are diverse, including pipeline and plug-in flow sensors;
High precision, typically measuring liquids with an accuracy of ± 1.0%; The measurement accuracy of gas is ± 1.5%;
The measurement range is wide, reaching up to 1:20 within the Reynolds number range of 2 × 104 to 7 × 106;
Low pressure loss (about 1/4 to 1/2 of orifice flow meters), belonging to energy-saving flow meters;
The installation method is flexible, and it can be installed horizontally, vertically, and at different angles according to the on-site process pipeline blockage;
Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance;
Adopting ultra-low power single-chip microcomputer technology, one 3V10AH lithium battery can be used for more than 5 years;
Correction of instrument coefficient nonlinearity by software to improve measurement accuracy;
Using EPROM for power down protection of accumulated traffic, with a protection time greater than 10 years;
