Dinel ULM-53 Manual

• For continuous level measurement of liquids
(even if polluted), mash and paste materials
in open or closed vessels, sumps, open
channels, etc.
• Configuration and adjustment of measuring
range by two buttons
• Xi version for usage in explosive areas
• State indication by two LEDs
• Current (4 ... 20 mA) or voltage (0 ... 10 V) output
• Options of inverse function
(20 ... 4 mA or 10 ... 0 V)
Ultrasonic level meters ULM
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 fl ight
of the acoustic wave to the level and back.
The level meters are suited to level measurement of various liquid materials, sewerage waters, mash and paste materials,
suspensions etc. In case the level of bulk-solid materials is measured, the measurement range is reduced. We recommend to
consult the use with the manufacturer.
All the setting is done by means of two buttons, located in the upper part of the sensor. Level meters are equipped with optimal
state indication "STATE" and the setting process "MENU". The level meters outputs can be current or voltage.
