Description

Oval gear flow meter is a volumetric meter for continuous or intermittent measurement. It has many advantages, such as wide flow range, high accuracy, small pressure loss, strong viscosity adaptability. And it can measure high temperature and high viscosity liquid with convenient calibration, installation features.

In addition, the oval gear flow meter can work for many different application scenario. It is used in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine and health departments.

AT-LC series oval gear flow meter is equipped with a pointer and number counter. It can directly display the liquid accumulation flow on the spot. The accumulative, quantitative and instantaneous flow remote transmission control can be realized by attaching the transmitter and the electric display instrument to the counting mechanism. High temperature and high viscosity liquid can be measured by adding radiator or ellipsoid under tooth.

Working Principle

Oval gear flow meter body chamber has a crescent cavity that is composed by a pair of oval gear and cover plate as the metering unit of flow. The oval gear is rotated by the pressure difference between the inlet and outlet of the flow meter so that the liquid is continuously measured by the crescent cavity and sent to the outlet. The liquid that flows every turn is four times of the crescent cavity. By sealing coupling, the total number of turns of oval gear and the speed of rotation are sent to the counting mechanism or transmitter. Thus, we can know the total amount of liquid and instantaneous flow through the pipeline.
