Flow Switches

SOR flow switches have proven to be workhorses in the process instrumentation industry. They are ruggedly built to exacting standards and provide long-lasting service. Our flow switches can be used in a wide range of pipe sizes and process configurations.  Mechanical vane type switches are designed specifically for liquid process medias.  Our electronic instruments can detect both liquid and gas process flow and are field selectable and adjustable.

Flow Transmitters

Flow measurement done by an SOR differential pressure transmitter measures the pressure drop caused by an obstruction in a pipe which is normally created by a filter or primary element. As the flow of the process material goes through the obstruction, the pressure drops. This measurement can then be used to determine an accurate measurement of flow either in volumetric flow rate or mass flow rate.
