Tankmasters are pressure sensing controls with high and low set points for control of liquid level in elevated storage tanks, standpipes or other vessels. Tankmasters may also be used anywhere in a system to maintain local pressure. Time delays before operation assure surge and backspin protection. The control also assure staggered re-starting in case of line failure. Any Tankmaster can be used as a transmitter to control a remote pump.
