The 918TCP provides an audible alarm for either a high or low level warning. The system incorporates an alarm box and a single-point level sensor.

• The alarm box is a weatherproof, intrinsically safe, 90 decibel alarm that operates on two 9-volt batteries. It features a mem-brane-type test/cancel button.


• The single point level sensor is immersed in the tank through a 2" NPT female opening and is supported by a nylon liquid tight cable connector, Teflon tubing and wire.
