Per Sensor
The non-invasive LVUN-600 Series
monitors liquid levels at 1 or more
points through pipes or tubing of
various sizes, from 6.3 mm (0.25")
diameter tubing to 305 mm (12")
diameter pipe, with a wall thickness
of up to 0.5". The sensor simply
clamps on the thick-wall pipe or tube;
no alignment is necessary. The
sensor is small, allowing mounting
at almost any location, without
interrupting the process or requiring
the modification of the pipe or
vessel. It is ideal for high-pressure,
thick-wall tubing pipes or sight
glasses.
The LVUN-600 Series can handle a
variety of liquid types–from heavy to
light. It uses ultrasonic sound wave
propagation to generate electrical
signals that are converted to bursts
of ultrasonic energy. The ultrasonic
bursts are transmitted across the
liquid sensing gap of the sensor.
Upon receipt of a valid signal at the
receiver, the solid state electronics
generate a “data enable” condition
indicating that liquid is present. This
signal energizes a relay, triggering
an output condition.
