KGF125 Gear Flow Meter

Introduction

Gear Flow Meter belongs to a kind of volumetric flow transmitter and can be us ed for measuring volume and flow precisely. The flowing medium makes the gear engage and rotate. Under the flowing effect of fluid, pressure difference is formed between the inlet and outlet of instrument. One pair of gears can rotate freely without the need of power supply. The empty cavity between gears is filled with liquid, which is discharged through rotation. The liquid flowing through instrument and liquid flow can be known through measuring the number of revolutions of gear.

principle

The rotation speed of the transmitter is detected by the sensing coil inside the signal amplifier on the case. The signal amplifier cannot contact the measured medium. The magnetic line of force generated inside the permanent magnet inside the case due to transmitter gear cutting will lead to flux change inside the sensing coil. The sensing coil sends the signal of flux change cycle detected to the pre-amplifier to amplify and shape the signal. The impulse signal which is in direct ratio with flow velocity will be sent to the unit conversion and flow integration circuit to obtain and display the accumulative flow valve. At the same time, it will also send the impulse signal to frequency current conversion circuit to convert the impulse signal to simulation amperage to display the instantaneous flow value.

The Gear Flow Meter has high processing precision and can be installed precisely. The gear rotation undergoes non-contact scanning. One impulse is generated by one gear with very high resolution. The column gear transmission can measure the liquid with very small flow and small quantitative volume.
