Municipal & Waste Water

Locations that process waste water need to determine if water is flowing at the correct minimum rate to ensure that the water treatment processes function correctly. The Harwil Q-5 & Q-16 Flow Switch in Brass or Q-5SS Flow Switch 316 stainless steel are used for these applications. This model is robust and will function without fail for years and years. Engineers at the City of Los Angeles even requested that we make a special model with indicator lights so the service people can see if the switch is opened or closed. The lighted model is now available to everyone.

The Harwil Wireless Switch Control is also popular in these environments. Often the maze of wires and pipes makes adding more wires difficult. The Wireless Sending Unit is attached directly to the Q-5 Flow Switch and the Wireless Receiving Unit is installed at the controlled device location. The switch’s position is transmitted which operates a 15 amp relay at controlled device location.   Harwil’s Harwil Wireless Switch Control can actually work with any kind of switch, not just Flow and Level Switches.
