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.
