Description

Ultrasonic Level Transmitters provide reliable, cost effective continuous measurement of fluids that do not contain foam, vapors, fumes or gases. Suitable for use in plastic, metal or concrete tanks, sumps, containers or other vessels. Integrated temperature compensation improves accuracy and the transducers, built-in self-cleaning operation reduces buildup or condensation. High efficiency narrow beam technology helps eliminate unwanted echoes from standpipes, tank walls or other structures. Single push button calibration and Gateway software make commissioning quick and easy.

Overview

Babbitt Ultrasonics Level Transmitters operate on the Time-of -Flight principle. The sensor generates a pulse that sends a sound wave from the transducer face down to the fluid level. The media reflects the signal and the transit time is converted into a 4/20mA output signal.

The proprietary circuitry uses smart signal processing to lock onto echoes farthest from the transducer face. This allows the unit to ignore peripheral obstructions when mounting close to vessel walls, piping or ladders. Sensors are designed to adapt to the internal tank conditions, automatically adjusting power and receiver sensitivity to any distance and reflecting surface. This technology ensures the same echo is maintained over the entire operating range, enhancing measurement accuracy. See video below for a short demonstration.
