Radar (FMCW) level transmitter for liquids in the water and wastewater industry
• Continuous, non-contact level measurement in tanks, pumping stations, open channels etc.
• Robust stainless steel design, waterproof (IP68 / NEMA 4X/6)
• 24 GHz radar, PP Drop antenna
• Measuring range: 0…20 m / 66 ft

The OPTIWAVE 1400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in water and wastewater applications. It is equally suited for continuous, non-contact level measurement of water from springs, rivers, lakes or the sea as well as rainwater, wastewater, sludge or other liquids in storage applications. The device features a robust stainless steel housing and comes IP68 / NEMA 4X/6 rated for use in open air installations prone to flooding.

Its proven PP (polypropylene) Drop antenna, with the smallest beam angle (8°) on the market, guarantees accurate and reliable level measurement of liquids despite condensation, turbulent surfaces or foam. This makes it a more powerful, yet cost-effective alternative to pulse radar and ultrasonic level transmitters. The level radar offers thread as well as low-pressure flange connections and various other accessories.
