True Echo Pulse Radar Level Transmitter For Liquids

True Echo Pulse Radar Level Transmitter For Liquids

PRL

Dependable Liquid Level Readings In a Wide Range of Environments

The True Echo™ PRL provides accurate level readings from all types of liquid level measurement, including oil-water interface measurement via additional firmware. 

Description

The True Echo™ PRL brings the unassailably accurate level readings of radar sensors to all types of liquid measurement.

Versatile Materials Two housing materials plus multiple antenna choices equals a sensor that operates anywhere you need it to.

Easy Wiring & Set-up From an isolated 4-20 mA output, to push-button field calibration, everything about the True Echo™ PRL is easy.

Oil-Water Interface Detector A firmware addition adds Oil-Water Interface detection to the True Echo™ PRL's already versatile capabilities.
