Krohne OPTIWAVE 1010 radar level transmitter

The OPTIWAVE 1010 radar level transmitter is designed for bypass chambers and magnetic level indicators. The 2-wire FMCW radar level transmitter is designed for the continuous level measurement of liquids in bypass applications in various industries, such as chemical, power, water and wastewater.

The product can be combined with the Krohne BM 26 ADVANCED bypass chambers and magnetic level indicators (MLI), thereby adding a 4–20 mA HART output to the mechanical devices. The combinations can be ordered as a whole or it can be welded on any bypass chamber with an internal diameter of 38–56 mm.

The unit is designed as an alternative to reed chains and magnetostrictive or simple TDR transmitters that are typically used with bypass chambers or MLIs. In addition to a measuring accuracy of ±5 mm, the FMCW principle is claimed to offer a better overall accuracy in bypass applications because it directly measures the liquid surface.

Applications include almost any liquids with process temperatures ≤150°C up to 580 psig and measuring ranges up to 8 m. With clean liquids of dielectric constant εr ≥3, the device measures the surface directly. For εr <3, a float with target is used.

The product features a dual process seal system that allows for the removal of the converter under process conditions. The 2-wire, loop-powered HART device is preconfigured in the factory and delivered ready to use. Application-specific adjustments are possible via HART/DD and DTM.
