Brief introduction
ACF-1WQL integrated intelligent venturi flow meter is a throttling flow sensor developed according to venturi effect. It is simple structure, no moving parts, stable and reliable in long-term use, high precision. High standardization degree, good linear, does not need solid flow calibration. Orifice meter use agile and convenient; differential pressure flow meter is still used widely in domestic flow meters currently, according to estimates of relevant data: the consumption of dp flow meter is 75% - 85% of the total consumption. It is widely used in the steam boiler, petroleum, chemical, steel, electric power, water conservancy, papermaking, pharmaceutical, food and chemical industries, etc.

Measure theory
When fluid filled with pipe flow through the throttling part, the flow will form local contraction at the venture throttling area to accelerate the flow and reduce the static pressure, then there will be pressure drop also called differential pressure before and after the venturi neck. The bigger of the medium flow rate, the bigger of the differential pressure, so we can measure the flow rate by measuring the differential pressure. This measuring method is on the theory of law of conservation of mass and law of conservation of energy.
