How to choose suitable tubine flowmeter

This instruction manual has not yet provided descriptions in respect to different characteristics of

users. By the way, when modifying technical parameter, structure or parts of the flow meter, as long

as such modifications cause no impacts on functions and operation of the flow meter, this instruction

manual will not be revised accordingly each time.
