Open Channel Flow Meter
Open channel flow meters are not like other flow meters as the applications that they are utilized in deal with open channels that are free flowing.
Instead of using mass or volumetric data to determine the rate of flow of a substance, open channel flow meters monitor the relationship between the depth of the liquid and the flow rate.
The reason for the differences compared to the other mechanical and pressure based flow meters is that due to the free surface in open channel applications, traditional flow meter strategies cannot take place as the top surface of liquid is open to the air.Read More…
In order to better understand open channel flow meters, one must first understand open channel flow. As stated an open channel flow is a flow of fluid where there is one free surface present in which the only pressure on it is that pressure of gravity.
