Pneumatic Float Switch
Model 106 - Low liquid level switch for cooling water expansion tanks - Automatic water make-up for cooling water expansion tanks - Low or high level switch for monitoring levels in tanks Model 207 The Model 207 utilizes a Model 106 installed in a carbon steel tank. The tank features a sight glass and the wetted parts are carbon steel, brass, glass and Buna-N seals. The switch is designed to function as either a pneumatic high or low switch or as an automatic water make-up valve.
