Specifications

This product is widely applicable in the industries of petroleum, petrochemical engineering, natural gas, chemical engineering,

Overview

The working principle of the oval gear flow meter is that a pair of elliptic gears is driven to rotate by liquid. The volume of every cavity is fixed. The revolution speed of the gear is acquired and the sensor sends out sync pulses to count. Then the rotation of the elliptic gear is transmitted to the counter through a magnetic sealed coupler and transmission speed reduction device to directly show the total amount flowing through the flow meter. If the transmitting device and electric display meter are equipped, it may transmit the instantaneous flow rate or cumulative flow rate over a long distance.

Features

The oval gear flow meter is mainly used to measure media of high viscosity. This product is widely applicable in the industries of petroleum, petrochemical engineering, natural gas, chemical engineering, paper-making, etc. which is used to measure and count micro flow rate in small caliber.
