Fuel Flow Meters Diesel Oval Gear Flow Meter
An 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 a large range, high accuracy, small pressure loss, strong viscosity adaptability, measurement of high temperature and high viscosity liquid, convenient calibration, installation suggestions,s and so on. It is suitable for flow measurement in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine, and health departments.
