136 ULT

The Ultrasonic Level Transmitter utilizes the Time of Flight principle to accurately and reliably measure levels. The device offers a high measurement accuracy of ±0.5% of FS standard and ±0.25% of FS on request with a 9° beam angle and minimum dead band. It provides a measuring range of up to 15 meters. The 136 ULT features a 2-wire configuration along with keypad display and delivers a 4–20 mA output signal with optional HART communication for improved integration and diagnostics. Its robust design and reliable performance make it ideal for a wide range of water and wastewater level measurement applications.
