Gear Flow Meter

Overview

Gear flow meter belongs to a kind of volumetric flow meter and can be used for measuring liquid volumetric flow precisely. The flowing medium makes the gear engage and rotate. Under the flowing effect of the fluid, pressure difference is formed between the inlet and outlet of the gear flow sensor. 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 can be known through measuring the number of revolutions of the gear.

How Gear Flow meter work?

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