Siemens Part # QVE1900U

Flow switches are used to monitor the flow of fluids in hydraulic systems, especially in refrigeration and heat pumps, and are for use with condensers, boilers, and heat exchangers. Detect the flow of the medium to be monitored by means of a paddle. If the flow velocity in the piping falls below the adjusted switch-off value, the paddle actuates a microswitch with a dry contact (S.P.D.T.), which closes the contact. When the flow velocity reaches the switch-on value again, the opposite contact closes
