Description
The Johnson Controls F261MEH-V01C is a paddle type flow switch used in the HVAC systems which is an acronym for Heating, Ventilation and Air conditioning systems. It measures the velocity of water in a pipe; it is suitable for use in environments with a maximum temperature of 250°F and pressure of 290 PSI. The NEMA 4 housing of this device means that it it can handle moisture and dust and fine particulate matter in the air. The paddle inside the switch floats and is hinged ; when an adequate flow of water passes through the pipe the paddle deflects.
