Cost-effective automation solution for level applications

KROHNE is expanding its range of radar level meters with two new products in the OPTIWAVE 15xx series: a version with local display for OPTIWAVE 1540 and OPTIWAVE 1560, and the SCU 200 control and signal conditioning unit, which is compatible with all OPTIWAVE 15xx devices. Together, these components form a modular and cost-effective automation solution for level applications, especially in the water and wastewater sector.

Launched in June 2024, the OPTIWAVE 15xx series has proven to be a reliable and affordable entry point into 80 GHz radar technology. Designed for basic applications, the devices feature a flush-mounted PVDF lens antenna and offer HART and Bluetooth connectivity. Their compact design, robust construction and intuitive commissioning via the OPTICHECK Level mobile app make them ideal for applications with liquids and solids. The new local display version enhances the flexibility of the OPTIWAVE 1540 and 1560, offering a cost-effective option for users who require on-site visualisation of measurement values.

The SCU 200 is a versatile control and signal conditioning unit for 4...20 mA field devices for processing measurement values and signalling tasks. It complements KROHNE’s OPTIWAVE radar level transmitters, OPTIFLEX guided radar devices and OPTIBAR pressure transmitters, and offers extensive functionality including dual totalisers, pulse output, sampling and pump control.

The SCU 200 supplies power to connected field devices, eliminating the need for additional power electronics. It’s clearly marked terminals simplify wiring, while the robust IP67-rated GRP enclosure supports wall, field or panel mounting. The configurable display features colour-changing LED backlight, trend indication, relay status and alarm signalling. Parameterisation is carried out via standard USB-C cable using dedicated software.

Particularly suited for pumping stations and sewage sumps, it also supports open channel flow measurement when paired with the OPTIWAVE 1540. In these installations, the combination of OPTIWAVE 15xx radar and SCU 200 controller provides a turnkey solution to replace traditional ultrasonic systems. Users benefit from reliable measurement, modern connectivity and a high degree of modularity to meet diverse application requirements at an attractive price point.
