Ultrasonic level meters ULM® is self contained device that includes electroacoustics transducer and electronic module. The level meter ULM transmits series of ultrasonic pulses which propagates towards the liquid surface. Refl ected acoustic wave is received back in the ULM transducer and processed in electronic module. The distance calculations are based on time of flight of the acoustic wave to the level and back.
The level meters are suited to continuous non-contact level measurement of liquids (water solutions, sewerage water, etc.), mash and paste materials (sediments, sticks, resins etc.) in closed or open vessels, sumps, reservoirs and open channels.
ULM–53L–__–I and ULM–53L–__–U level meters has no customer accessible adjusting elements. Customer choice of the maximum measurement range (factory settings), The outputs can be current (4 … 20 mA) or voltage (0 … 10 V).
ULM–53L–__–M level meters has no customer accessible adjusting elements. Two-way communication (parameterization) by RS–485 Modbus RTU protocol.
