Product Description
Marine LC Type Ellipse Gear Flowmeter
Product Introduction:
Our Marine Ellipse Gear Flowmeter is a positive displacement flow meter designed for precise measurement of viscous, clean, or lubricating liquids in marine applications. It operates on the elliptical gear principle, where two interlocking elliptical gears rotate with each volume of liquid passing through, ensuring high accuracy and repeatability.
Ellipse gear flowmeter is a volume type flowmeter, which measure liquid summation through pipeline. It can be used for ship, chemical, petroleum, medicine, electric power, metallurgy and food etc.
