AquaWave 138 W52

The Radar Level Transmitter Liquid (138 W52) is a high-performance, non-contact level sensor designed for precise easurements in various water applications. It uses advanced FMCW radar technology, ensuring accuracy with respect to the surrounding environmental conditions. The device offers a high measurement accuracy of ±5 mm with an 8° beam angle, a 150 mm dead band and operates within a temperature range of -10°C to 60°C. It provides a maximum measuring range of up to 30 meters. The 138 W52 features a two-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.
