Krohne, a provider of industrial process instrumentation, is introducing the OPTIWAVE 1530 and OPTIWAVE 1560 radar FMCW level transmitters for solids and liquid applications such as small to tall silos, narrow tanks, stockpiles, bunkers, and vessels with internal obstructions
This technology provides a solution for the metals, minerals, mining, and water and wastewater industries by delivering accurate, non-contact measurement of solids and liquids.
The OPTIWAVE 1530 is a cost-effective solution with a measuring range of 0-15m, making it suitable for small to medium silos, stockpiles, bunkers, and tanks. The OPTIWAVE 1560 extends this capability to 30m for long-range measurement in tall silos, large tanks, and deep vessels. Both models provide drift-free, maintenance-free operation without requiring recalibration over the lifetime of the product, reducing total cost of ownership.
Designed for durability, both models are compact and robust with fully potted electronics to protect internal components from dust, condensation, vibration, and shocks. The flush-mounted, concave PVDF lens antenna provides chemical resistance and a self-draining design to prevent buildup, maintain a stable radar signal, and ensure consistent performance.


With a 4° beam angle, these transmitters can achieve exceptional accuracy in tight spaces and vessels with internal obstructions by avoiding interference from fixtures and walls. Their high dynamic range ensures reliable performance on dusty surfaces, foamy or agitated liquids, condensation, or poorly reflecting media. Almost no dead zone maximises the usable measurement range, even in small tanks.
Installation is done with a unique 3” threaded connection that fits standard flanges and accessories without protruding into nozzles, preventing potential measurement interference. For extreme conditions, an optional IP68-rated waterproof version provides protection in heavy rain, outdoor dusty environments, and flood-prone areas.
Commissioning and operation are streamlined with Bluetooth connectivity on the OPTICHECK Level Mobile app, enabling safe, remote setup from the ground, with no climbing tanks or silos required. Pre-configured application templates in the app provide step-by-step guided setup, as well as the flexibility needed to switch measurement parameters for other applications, helping to adapt to changing process needs. HART communication with OPTICHECK DTM enables quick integration into control systems, and built-in OPTICHECK diagnostics monitor device health to decrease downtime.
Maintenance and compliance are simplified with on-site verification that requires no process interruption, a one-link verifiable status report for documentation, and advanced algorithms, including Tank Bottom Management, to filter false echoes and ensure accurate empty tank detection. Each device features a 5m shielded cable, comes backed by a three-year warranty, and provides a range of accessories such as flanges, weather covers, and brackets.
