APG True Echo Plus Submersible Radar Level Transmitter

The APG True Echo Plus Submersible Radar Level Transmitter combines level readings of the CR-L Radar with the PT-400 pressure transducer. Combined they form a versatile dual sensor that detects and measure overfill or flood conditions, providing clear information when systems overflow.

The radar’s narrow beam can detect small targets and achieve precise positioning with high resolution. IT has a maximum measuring range of 49.2 feet (15m) and an 8 inch (0.2 meter) minimum blind zone. Sensor can be setup and field adjusted with the True Echo Bluetooth app. 

When the radar is submerged due to rising liquid levels, the pressure sensor continues the monitoring. The 30 psia sensor uses the same technology as APG’s PT-400.
