Twice the Tech For One Smart Solution
The TRUE ECHO® Plus combines the accurate level readings of the CR-L radar with the precision pressure measurement from a submersible pressure transducer. Together they form a versatile dual sensor that is uniquely engineered for detecting and measuring overfill or flood conditions so you don’t have to operate in the dark when systems overflow.

With a maximum measuring range of 49.2 feet (15 m) and a minimum blind zone of just 8 inches (0.2 m), it’s ideal for applications where space is limited and precision is non-negotiable. Setup and adjustments are a breeze using the intuitive TRUE ECHO App.

When levels rise and the radar is submerged, the integrated submersible pressure transducer takes over—ensuring continuous, reliable monitoring through every condition. Built with rugged, heavy-duty wetted materials, the TRUE ECHO Plus is engineered to perform in the toughest environments.

From flood alerts to overfill prevention, TRUE ECHO Plus keeps you ahead of the curve. PT-500-P1
DESCRIPTION
Features
Quality and reliability you can trust
The PT-500–P1 Submersible Pressure Transmitter for clean liquids offers unparalleled reliability and accuracy in industrial applications. Built with lightning transience protection, Class 1, Div. 1 certification, and field-adjustable zero, this pressure transducer is designed to provide precise measurements in harsh environments. Featuring a durable 316L SS sensor, vented urethane cable, and a compact Delrin nose cone, the PT-500–P1 is ideal for use in clean liquids with depths up to 575 ft (250 psi). It includes conduit mounting threads, a built-in vent tube filter cap, and an optional NIST certificate for calibration accuracy to 0.1% full scale.
