Designed to indicate "pump on" and "pump off" conditions within a forced cooling system. Select models also indicate flow direction. Up to 2 SPST or SPDT switches are available for control and/or alarm functions. Large dial face provides easy viewing and is magnetically coupled to the flange assembly allowing quick replacement if damaged.
Application: For power transformers with forced oil or water cooling systems which require "safe" flow rate, "correct" flow direction, on-off control, limit control or alarm triggering.
