OPTIWAVE 1400 with G thread

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.

Product highlights

  • 2-wire, loop-powered, with HART®7
  • FMCW technology for greater resolution, just like the new 80 GHz generation
  • Proven PP Drop antenna, insensitive to condensation or deposits
  • Narrow beam angle (8°) for a sharp focus on the medium
  • ± 2 mm / 0.08" accuracy
  • Robust stainless steel design
  • Maintenance-free concept
  • Installation and operation made simple, safe and secure
  • PACTware™ HART® DD and DTM provided free of charge with full functionality
  • 3-year warranty

Typical applications

Water and wastewater inductry

  • Liquid level measurement during extraction, transport, storage and distribution of water from springs, rivers, lakes or the sea
