Cellular Ultrasonic Level Transmitters provide continuous level measurement of fluids in remote applications that do not contain foam, vapors, fumes or gases. These extremely low-power ultrasonic sensors contain built-in cellular modems and are plug-and-play, automatically connecting to a fully secured server for ease of installation and remote monitoring, so there is no need to set up SIM cards. The cellular non-contact ultrasonic sensor is powered with continuous 12-30VDC and provides level measurement up to 60 feet with a 4/20mA output and features simple push button or remote calibration. The cellular modem provides the user with full control, remote monitoring and access to 24/7 virtual support.
Overview
Cellular 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.
Sanitary Cellular Ultrasonic
The sanitary cellular ultrasonic is the ideal solution for non-contact continuous level measurement in remote sanitary/hygienic liquid-level applications. These units have a 316L stainless steel transducer face and are available in either 1 ½” or 2” tri-clamp mounting with a maximum range up to 30 feet. The sanitary stainless-steel ferrule allows for process temperatures up to 266°F while the HTP (high temperature and pressure) option can withstand clean-in-place (CIP) processes up to 266°F and 72 PSI for ½ hr.

High-Temperature Ultrasonic
The high-temperature cellular ultrasonic is the ideal non-contact, continuous liquid-level measurement solution in remote applications with high-temperature processes. These units have a corrosion-resistant Teflon transducer and are rated up to 266°F (130°C). High-temperature ultrasonic level sensors provide self-cleaning, maintenance-free operation and plug-and-play installation with remote monitoring.
