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.

Features

As a kind of new volumetric flow meter, the gear flow meter is used for measuring the flow or instantaneous flow of the liquid inside pipeline precisely, either in a continuous or discontinuous flow.
It is particularly suitable for the measurement of heavy oil. Flow measurement of media with high viscosity such as vinol and resin. (It can be used for measuring the fluid the viscosity of which is as high as 10,000 mPa.s) , Gear flow meter has small volume, light weight, small operation noise and stable operation. It can also be used for measuring the micro flow of small pipe diameter. With small startup flow and broad range ratio, it is applicable to the measurement of liquid flow with significant change and its measurement precision is not affected by either pressure or flow change. It is stable in performance, long in service life and large in circulation capacity.
