 Orifice Flowmeter Working Principle
Q&T orifice flowmeter pipe-filled fluid flows through the throttling device in the pipe, causing local
contraction near the throttle, increasing the flow rate, and creating a static pressure difference on
both the upper and lower sides. Under the condition that the relevant parameters are known, the
flow rate can be obtained by deriving the relationship between the differential pressure and the
flow rate according to the principle of flow continuity and the Bernoulli equation.

Q&T orifice flowmeter is a high-range differential pressure flow device composed of a standard orifice plate
and a multi-parameter differential pressure transmitter, which can measure gas, The flow of steam, liquid and
lead is widely used in process control and measurement in petroleum, chemical, metallurgy, electric power,
heating, water supply and other fields. Flow measurement of steam and liquid.
The utility model has the advantages of simple structure, convenient maintenance and stable performance
