Oval gear flowmeter is a volumetric meter for continuous or intermittent measurement and control 

of liquid flow in a pipeline. It has many advantages, such as large range, high accuracy, small pressure 

loss, strong viscosity adaptability, measurement of high temperature and high viscosity liquid, convenient 

calibration, installation suggestion and so on. It is suitable for flow measurement in petroleum, chemical, 

chemical fiber, transportation, commerce, food, medicine and health departments. 

DH900 series oval gear flowmeter is equipped with a pointer and printing wheel accumulation device,

 and can directly display the liquid accumulation flow through the pipeline 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 undertooth. 

The flowmeter for different liquids (acids, bases, salts, organic solutions, etc.) can be made of 

different materials.
