What Is an Integral Flow Orifice/DP Transmitter?
Bernoulli's equation states that the pressure drop across a constriction is proportional to the square of the flow rate. Using this equation, smart differential pressure transmitters can infer the flow.
In this type of application, it is not only important to have an accurate differential pressure transmitter, but also an accurate "constriction". It is the accuracy of the total system that must be considered.
Therefore, Yokogawa combines an Integral Flow Orifice (IFO) with our DP transmitter in one unit to produce a total system to measure low flow accurately.
