EchoTouch™ GP 3-Wire Ultrasonic Transmitter
 
美国FLOWLINE LU20,LU30超声波液位计
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
美国FLOWLINE LU20,LU30超声波液位计Integral relay for alarm or automatic fill-empty control
美国FLOWLINE LU20,LU30超声波液位计LED digital display indicates level in inches or centimeters
美国FLOWLINE LU20,LU30超声波液位计EasyCal simple push button calibration for all user set points
美国FLOWLINE LU20,LU30超声波液位计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.
