OPTIWAVE 1400 C –
Focus is everything

OPTIWAVE 1400 C –
The FMCW radar with a sharp focus on liquids

Featuring a robust IP68 design with wetted parts made of stainless steel
and polypropylene (PP), this level transmitter perfectly fits the require­ments of the water and wastewater industry.

Just like all previous non-contact radar transmitters from KROHNE, the
new OPTIWAVE 1400 C uses FMCW radar technology. Its proven PP Drop
antenna, with the smallest beam angle on the market, guarantees a sharp
focus on liquids, unsusceptible to condensation, turbulent surfaces or
foam.

Competitive in price, easy to install and operate, the OPTIWAVE 1400 C
ensures continuous level measurement without maintenance over a long
period of time.

Applications

Ideal for liquids in the water and wastewater industry, or other fields
with liquid storage applications:

• Extraction, transport, storage and distribution of water from
springs, rivers, lakes or the sea

• Rainwater basins

• Open-channel flow measurement and floodwater alarms

• Water, wastewater, sludge or other liquids in storage applications

• Wastewater pumping stations

• Liquid level of plastic tanks (e.g. IBC)

Measuring principle

The radar principle used is called FMCW
(frequency modulated continuous wave).

An FMCW radar continuously emits a linear,
frequency-modulated signal with a con­stant amplitude (sweep). The distance to the
product is measured indirectly by using the
frequency difference between the emitted
and the received waves.
