The ULM
ultrasonic level meters are compact measurement devices containing an ultrasonic
®
transmitter and an electronic module. Using an transmitter, level meters transmit the series of
ultrasonic pulses that spread towards the level surface. The transmitter recuperates reflected
acoustic waves that are subsequently processed in the electronic module. Based on the period
during which the individual pulses spread towards the level and back, this period is averaged by
the electronics that performs temperature compensation and subsequently a conversion to an
output current (voltage) or Modbus communication.

aPPlication
The level meters are suited to continuous non-contact level measurement of liquids (water solu-
tions, sewerage water, etc.), mash and paste materials (sediments, sticks, resins etc.) in closed
or open vessels, sumps, reservoirs and open channels. In case the level of bulk-solid materials is
measured, the measurement range is reduced.
ULM–53L–__–I and ULM–53L–__–U level meters has no customer accessible adjusting ele-
ments. 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.
