Working Principle:

LWGY-A type battery powered turbine flowmeterThe impeller inside rotates under the action of fluid, causing a change in the magnetic field of the signal detector. Therefore, an alternating voltage is induced in the coil of the signal detector, which is amplified, filtered, and shaped by an amplifier to output a square wave signal. The frequency of this signal voltage is directly proportional to the speed of the impeller, that is, directly proportional to the flow rate (velocity) of the fluid.Battery powered liquid turbine flowmeter

Instrument Introduction:

LWGY-A type battery powered turbine flowmeterIt is a new type of intelligent instrument developed using advanced ultra-low power single-chip microcomputer technology, which integrates turbine flow sensors and display integration. It adopts dual row LCD on-site display and has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost. The instrument has three-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on site. The high-definition LCD display simultaneously displays instantaneous flow rate (4 significant digits) and cumulative flow rate (8 significant digits, with reset function).

Battery powered turbine flowmeterFeatures:

1High quality alloy turbine flow meters have higher stability and corrosion resistance;

2Imported high-quality bearings with long service life;

3The isolation between the measuring room and the ventilation room ensures the safety of the instruments;

4. It can detect the temperature, pressure, and flow rate of the tested gas, automatically track and compensate for the flow rate, and display the accumulated gas volume under standard conditions (Pb=101.325KPa, Tb=293.15K); Real time temperature and pressure values can be queried.Battery powered liquid turbine flowmeter
