GENERAL DESCRIPTION

LVLIO(I

OMEGA’S

Series non-contact ultrasonic distance

transmitter measures, displays and transmits the distance of
objects located in front of the sensor in the range from 0.5 to
30 feet, with an accuracy of up to 1%. It is suitable for

measuring liquid levels in tanks open to the air
PSIG), certain solid levels (consult Flow department for
details), as well as other eneral distance measurements. All

display with 0.1 inch resolution.

units feature a 4-digit

ib

L
Versions are available with one or two alarm relays, analog
4-20

K-232
wa computer communications, and a remote transducer
wrt up to 40 feet of cable.

*‘c

LV400

Setting the limits of the

alarms and analog output can
be performed manually by presenting targets at the desired
setpoints, or by entering the exact distance value (in inches)
by computer

communrcation. Alarm setpoints equal the
analog output span. Temperature compensation for
variations in air temperature is done automatically by
placing a reference target at an exact distance away from
the sensor.
