OPTIWAVE 1010: New radar level gauge

With the OPTIWAVE 1010, KROHNE introduces a new radar level gauge for reference vessels and magnetic bypass level indicators. The 2-wire FMCW radar level meter is a cost-effective solution for continuous level measurement of liquids in bypass applications in various industries, e.g. chemical, energy, water and wastewater or in the automotive industry.

The OPTIWAVE 1010 can be combined with the KROHNE BM 26 ADVANCED reference vessels and magnetic level indicators (MLI), thus adding a 4...20mA HART output to the mechanical devices. The combinations can be conveniently ordered as a unit, e.g. as BM 26 W1010 (OPTIWAVE 1010 welded to BM 26 ADVANCED). Alternatively, the device can be welded to any reference vessel with an inner diameter of 38...56 mm / 1.5...2.2" . This also makes it the ideal solution for other MLI manufacturers, who can hereby expand their product portfolio with an option for radar level measurement.

The OPTIWAVE 1010 is price positioned as a replacement for reed chains, magnetostrictive and simple TDR level meters commonly used with reference vessels or MLI. In addition to a measuring accuracy of ± 5 mm / 0.2" , the FMCW principle offers significantly better overall accuracy in bypass applications: While reed chains and the magnetostrictive principle measure the float position, which depends on the product density, the FMCW radar directly measures the surface of the liquid. The application range of the OPTIWAVE 1010 includes almost all liquids with process temperatures ≤ +150°C / +302°F up to 40 barg / 580 psig and measuring ranges up to 8 m / 26.2 ft. For liquids with a dielectric constant εr ≥ 3, the instrument measures the surface directly; for εr < 3, a float with target is used.
