The SLU ultrasonic level meters are suitable for continuous non-contact level measurement of liquids (water solutions, waste water sewage), mash and paste materials (sediments, resins etc.) in closed or open vessels, sumps, reservoirs and open channels. In the case of bulk-solid materials, the measuring range is reduced, but can be amplified or compensated by using the horn accessory.
