Gear Flow Meter is a type of volumetric flow transmitter. It is a transmitter for measuring volume flow with high precision.
With the flow of the medium, the gears mesh and rotate. Under the action of the fluid flow, a pressure difference is formed at both ends of the meter’s inlet and outlet. No power supply is required, and a pair of gears rotate freely. The cavity between the gears is filled with liquid, and the liquid is drawn by Discharge. Measuring the number of revolutions of the gear can know the flow of liquid and liquid flowing through the instrument.
The speed of the Gear Flow Meter is detected by the sensing coil in the signal amplifier installed on the case. The signal amplifier is not in contact with the measured medium.
When the transmitter gear cuts the magnetic field lines generated by the permanent magnet in the housing, it causes a change in the magnetic flux in the sensing coil.
The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier. The signal is amplified and shaped to generate a pulse signal proportional to the flow velocity. It is sent to the unit conversion and flow integration circuit to obtain and display the cumulative flow value.
At the same time, the pulse signal is also sent to the frequency current conversion circuit, which converts the pulse signal into an analog current, and then indicates the instantaneous flow value.
Gear Flow Meter has high processing precision and precise installation. The rotation of the gear is scanned non-contact. Each tooth produces a pulse with very high resolution. Spur gear transmitters can measure very small flow rates and quantify small volumes of liquid.
The pressure drop of a gear flow meter is related to factors such as the viscosity and flow rate of the medium. You can refer to the graph below. Alternatively, you can contact us to confirm the accurate pressure drop.
