Liquid Turbine Flow Meter

Output pulse frequency signals, applicable

to the total amount measurement and

computer connection, no zero drift, strong

anti-interference ability.

Liquid turbine flow meter range width,

middle and large caliber diameter up to 1:

20, small caliber for 1:10.

Compact and lightweight structure,

easy installation and maintenance,

large flow capacity.

Applicable to high-pressure measurement, the

instrument body does not need to open

holes, making it easy to make high-pressure

type instruments.

Liquid turbine flow meter can be made into insertion type,

applicable to large-caliber measurement, small pressure loss,

low cost, can be taken out without stopping the flow, easy to

install and maintain.
