Radar Level Transmitters Product Description
The WL900 Radar Level Transmitters offer a logical
extension to ultrasonic devices, where application
conditions are in need of non-contact liquid level
measurement but ultrasonic level transmitter measurement
is not acceptable. The WL900 Radar Level Transmitters
are ideal for a variety of water and wastewater
applications where you have a reflective liquid that has
a foaming surface, vapors, or dusty conditions beyond
ultrasonic transmitter capabilities. The Radar Level
Transmitters are also unaffected by temperature,
vacuums, pressure, methane, or CO2.
The WL900 Radar Level Transmitters use
state-of-the-art radar pulse technology which provide
accurate and reliable level measurements over their wide
10 inch to 50 foot range. With their simple push-button
calibration system, the WL900 Radar Level Transmitters
are easy to set up and maintain on the bench or in the
field by following simple instructions. Simply aim the
WL900 Radar Level Transmitters at your low range level
set point and push the button to lock in the setting –
do the same with the high level set point. This may be
done before permanently installing the Radar Level
Transmitter by aiming at a wall and using a tape measure
to determine your exact range.
The WL900 Radar Level Transmitter's rugged NEMA 4
(IP65) housing is available in either aluminum or 316L
stainless steel for corrosive environments. A standard
2” NPT(M) process connection allows for quick and
versatile installation of the Radar Level Transmitter.
The Radar Level Transmitter's polypropylene antenna rod
is virtually corrosion proof.

Water Level Sensor
When ordering, specify water level range that will
cover the maximum water level change for your
application (this is not necessarily the total depth
of water): 0-3', 0-15', 0-30', 0-60', 0-120',
0-250', and 0-500'. NOTE: There is a $50 extra
charge for 0-500' range sensor. Selecting the
smallest water level range possible will ensure the
greatest accuracy. Includes 25 feet of cable. |
