- Product description
Brief introduction
ACF-1-KB multi-parameter orifice flow meter is of 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.
Orifice flow meter installation requirement: 10DN in front of and 5DN behind of the straight pipe. Be sure to choose suitable flow meter according to the field condition when you consider buying one.
Measure theory
When fluid filled with pipe flow through the orifice, the flow will form local contraction at the throttling area of the orifice to accelerate the flow and reduce the static pressure, then there will be pressure drop also called differential pressure before and after the standard orifice. 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.
