Features

    1.No moving parts, long-term stability, simple structure for easy installation and maintenance;

    2.Sensor output is pulse frequency, its frequency is linear with the actual flow rate of the measured fluid, the zero point has no drift and the performance is very stable, structure style is diverse, there are pipeline type and plug-in flow sensor type;

    3.High accuracy, usual liquid measurement accuracy is ±1.0%; gas measurement accuracy is ±1.5%;

    4.Wide measuring range, with the range of Reynolds number 2×104~7×106, it can be up to 1:20;

    5.Small pressure loss (about 1/4~1/2 of orifice flow meter), which belongs to energy saving flow meter.

    6.Flexible installation method, according to the different field process pipeline, it can be horizontal, vertical and different angle tilt installation;

    7.It adopts the anti-jamming circuit and anti-vibration sensor and it has certain anti-environmental vibration performance.

    8.It uses ultra-low power single chip microcomputer technology, 1 section of 3 V10AH lithium battery can be used for more than 5 years;

    9.Non-linearity of instrument coefficients is corrected by software to improve the measurement accuracy.

    10.Use EEPROM for power-down protection of accumulated flow over a period of more than 10 years.
