Non-contact level measurement using ultrasonic pulse technology.
An ultrasonic level transmitter measures level by emitting high-frequency sound pulses towards the product surface and calculating the return time of the reflected echo. The measured distance is converted into a continuous level output, allowing accurate monitoring without contact with the process media.
The ultrasonic transmitter range includes compact and remote-mounted instruments for tanks, sumps, silos, open channels and wastewater applications, with measuring ranges extending up to 20 metres, analogue 4-20 mA, HART and Modbus communication, and IP-rated enclosures for indoor and outdoor installations.
Dutco Tennant LLC is a premium supplier of instrumentation and process measurement solutions across the UAE and GCC, offering a comprehensive portfolio for the water, wastewater, chemical, oil and gas, food processing and infrastructure sectors.
Non-Contact Measurement for Demanding Industrial Processes
- Time-of-flight technology delivers continuous level measurement without contact with the process media.
- Automatic temperature compensation maintains measurement stability despite ambient temperature changes.
- Narrow beam angle improves echo detection inside tall vessels and confined tanks.
- Suitable for liquids, slurries, wastewater and coarse bulk solids without mechanical wear.
- Compact sensor construction reduces installation requirements on new and existing vessels.
Integrated Functions for Reliable Process Control
- Echo Processing: Advanced signal filtering distinguishes the true product surface from false echoes created by internal tank obstructions.
- Self-Diagnostics: Continuous sensor monitoring reports operating status and diagnostic information to the control system.
- Communication Options: Available with analogue outputs alongside HART and Modbus protocols for PLC, DCS and SCADA integration.
- Weather-Resistant Housing: IP65, IP66 and IP67 enclosure options support indoor and outdoor installations.
- Configuration Interface: Local display, keypad or remote programming simplify commissioning and parameter adjustment.
