Liquid Level
Level measurement is one of the more essential measurements in a process. Incorrect measurements can cause tanks to overflow creating potential safety or environmental problems; or, low levels can cause pump damage. Even wrong intermediate levels can result in an inferior quality product. Whether the application is for monitoring or control, the level measurement needs to be accurate, reliable, and quick.

Low Flow
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 our DP transmitter with an Integral Flow Orifice (IFO) in one unit to produce a total system to measure low flow accurately.
