TWO-WIRE ULTRASONIC
LEVEL TRANSMITTER
The LVU-201A 2-wire ultrasonic level
transmitter is the compact solution
for non-contact continuous level
measurement in process vessels,
storage tanks, and open channels.
This loop-powered device provides
accurate level measurement up to
5.5 m (18') and is the ideal choice for
more challenging coating or scaling
liquids, including sodium hydroxide,
wastewater, resin, wax, liquor,
and bleach.
An ultrasonic sound wave is pulsed
2 times per second from the base of
the transducer. The sound wave
reflects against the process medium
below and returns to the transducer.
The microprocessor-based
electronics measure the time of flight
between the sound generation and
receipt, and translates this figure into
the distance between the transmitter
and process medium below.
Comes with complete operator’s manual.
The above-mentioned prices are based on the general purpose transmitter configuration.
Ordering Example: LVU-201A, ultrasonic 2-wire transmitter, loop-powered 4 to 20 mA, $850.
CSA-approved intrinsically safe configuration with ISB-201A.
Ordering Example: LVCN-51, continuous relay controller with LED display, $425.
For CE-approved controller configuration, add “CE” to model number and add $30 to price.
The CE-approved configuration complies with EN50082-2 immunity and EN55011 emission
standards.
