RusAutomation ULM-53 Series Instruction Manual

• For continuous level measurement of liquids
(even if polluted), mash and paste materials in
open or closed vessels, sumps, open channels,
etc.
• Variants of level meter with adjustment by two
buttons, or by magnetic pen
• Xi version for usage in explosive areas
• State indication by two LEDs
• Current output (4 ... 20 mA), voltage output
(0 ... 10 V) or RS-485 Modbus output
• Wide choice of electric connection via connectors,
cable glands or protective conductor
• While used with horn adapter can be measured
also some difficult media (foamy levels, loose
materials, etc.)
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 tem-
perature compensation and subsequently a conversion to an output current 4 -20 mA, voltage 0 - 10 V or output RS-485 Modbus.
The ULM ultrasonic level meters are suitable for continuous non-contact level measurement of liquids (water solutions, sewer-
®
age 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.
All setting-up is done using two buttons positioned in the upper part of the sensor. The level meter is equipped with optical state
indication (STATE) and with a setting-up process (MENU). The level meter can output current or voltage signals. They are manu-
factured in model versions for non-explosive areas (N) and explosive areas (Xi).
