Flowmeter working principle:
The V-type flowmeters is a differential pressure flowmeters, it get differential pressure to reflect flow rate through throttle. Throttling set is a cone a hanging in the pipeline central. High pressure the static pressure upstream pH (positive pressure) gets from the wall before the cone, low pressure(the pressure downstream) PL (negative pressure) gets from cone central, square root of the differential pressure DP is proportional to the flow.Type | Name | structure & application | sensor accuracy | pressure tapping | straight pipe require |
