EchoTouch™ GP 3-Wire Ultrasonic Transmitter

Application

The general purpose three-wire ultrasonic transmitter provides non-contact level measurement up to 24' or 7.4m with an internal relay that can be configured as a single-point alarm or latched on two points for automatic fill or empty control. The transmitter is ideally suited for challenging corrosive or waste liquids and is typically selected for atmospheric bulk storage and waste sump applications. Media examples include wastewater and resin.

Features
	Integral relay for alarm or automatic fill-empty control
	LED digital display indicates level in inches or centimeters
	EasyCal simple push button calibration for all user set points
	PP enclosure rated NEMA 4X with rugged PVDF transducer

Tech Tip
For applications with surface foam, turbulence or limited measurement space, install the transmitter in a 2" stand-pipe.
