PRL True Echo Pulse Radar Level Transmitter 05972

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.

• Ranges to 17, 50, or 100 feet
• ±0.25% of measured range accuracy
• 6.1 μA output resolution
• Field configurable 4-20 mA/20-4 mA Output
• RS-232, RS-485, or HART communications
• PC calibration, diagnostic and data logging software
• PLC compatible (Modbus RTU)
• Nema 6/ IP68 enclosure rating
• Simple installation and setup
• Automatic adjustments for most tank conditions
• Very low material dielectric constant requirement
• Low Dielectric Material mode for ε < 4
• Firmware addition for Oil-Water Interface measurement
• Optional Fast Firmware for quickly changing levels
