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.

In some cases this type of flow can also be referred to as free gravity flow. There are a number of different types of open channel flow depending on the environment that they are found in as some have no changes in the depth of liquid where others have a constant, unsteady flow. Because there are so many variables in open channel flow, there must also be a wide range of selection when it comes to open channel flow meters.

These devices typically consist of ultrasonic or special radar styles that are still able to function while traditional pressure based flow meters do not due to the free surface found in open channel flows.

While these flowmeters can be used in a number of industries, the two most common are in wastewater and the water industries as these are the two most common liquids that are found in open channel flows.

Whatever your application may be, it is important to find a knowledgeable expert on the topic before making a purchase in order to ensure that the product you are receiving is a product that will meet and exceed your expectations. We recommend high quality flow meter manufacturers who will listen to your application and suggest the best flow meter for you based on your needs and specifications.
