OPTIWAVE 1400 Radar Level Transmitter

The OPTIWAVE 1400 is a 2-wire 24 GHz radar level transmitter (FMCW) for liquids in water and wastewater applications. It is ideal 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. This radar level transmitter features a robust 316L stainless steel housing and comes with an IP68 / NEMA 4X/6 rating 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 powerful, yet cost-effective alternative to pulse radar and ultrasonic level transmitters. The OPTIWAVE 1400, from KROHNE, offers thread as well as low-pressure flange connections and various other accessories.

Features of the OPTIWAVE 1400 Radar Level Transmitter*

• 2-wire, loop-powered, with HART 7
• FMCW technology for greater resolution, just like the new 80 GHz generation
• its proven polypropylene Drop antenna is insensitive to condensation as well as deposits
• narrow beam angle (8˚) for a sharp focus on the medium
• TBM (Tank Bottom Management) ensures reliable measurement, even in empty tanks:
  • dedicated algorithms to filter and compensate for irregular radar wave reflections that occur at tank bottom when the vessel is empty
  • also allows for quick and easy commissioning of tanks regardless of size, material, or geometry
• ±2 mm (±0.08″) accuracy
• maintenance-free concept
• installation and operation is simple, safe, as well as secure
• extensive choice of accessories
• PACTware, HART DD, and HART DTM – free of charge with full functionality
• 3-year warranty
• hazardous area approvals

Common Applications of a Radar Level Transmitter

• liquid level measurement during extraction, transport, storage, and also distribution of water from springs, rivers, lakes, or the sea
• level measurement in rainwater basins
• open-channel flow measurement
• level measurement of water, wastewater, sludge, as well as other liquids in storage applications
• level monitoring in wastewater pumping stations
• floodwater alarm
• level measurement of liquids in plastic tanks (e.g. IBC)
