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.
