Krohne OPTIWAVE 1520 and 1540 radar level transmitters

Krohne has released the OPTIWAVE 1520 and OPTIWAVE 1540 2-wire 80 GHz radar level transmitters with HART and Bluetooth for basic applications. The devices are compact and come with a flush-mounted antenna and a robust PVDF housing. Both devices are waterproof (IP68) and can be used for both liquids and solids.

The OPTIWAVE 1520 is suitable for use in confined spaces and in open-air applications. Typical applications include the measurement of sewage sludge, wastewater and treated water, such as in pumping stations, on screw lifts and above water basins. Due to its small beam angle, OPTIWAVE 1520 is also suitable for small silos with granulate solids such as sand, or for small tanks with internals as well as for level measurements that do not allow a dead zone. Within its measuring range of 0-10 m, it offers a measuring accuracy of ±5 mm.

The OPTIWAVE 1540 is resistant to many chemicals and contaminated liquids and offers level measurement in mobile containers (IBC tanks), in chemical tanks (up to 5 bar), in water and wastewater applications and in granulate solids silos. It offers measuring accuracy to ±2 mm over a measuring range of 0-15 m. The radar device can also be used as a simple flow meter in open channels to determine the flow based on the height and geometry of the venturi channel.

Using the quick setup wizard, both devices can be quickly set up and commissioned via Bluetooth using a smartphone or tablet and the OPTICHECK Level Mobile app.
