Installation:
Radar Sensor:
The Radar Pro™ should be installed over the top of the tank. The vertical
xed method is best for highest accuracy. The measure reference surface is
the bottom line of the sensor. The highest solid level cannot enter the blind
area.The level measurement should avoid the feeling hole; aim toward the
smoother level surface. It is better to use a sun/rain shade when mounting in
an application that is exposed to weather elements. When mounting, sensor
should be kept a distance from the wall surface because of the beam. When
measuring the object level, the feeding hole should be avoided to prevent
interference with the ultrasound echo.
Mounting Bracket:
Using the bracket as a template, place a level
across the top and hold it in the desired location.
Mark the four 3/16” holes. Use a drill bit suitable
for the intended substrate and screw diameter and
drill out the four holes (A 10-32 x 1 1/2” stainless
steel screw is recommended). The mounting holes
can be bored to 1/4” to accept a larger screw (A
minimum of 1” penetration into the substrate is
recommended).The tolerances of the drill bit used
should meet the requirements of ANSI Standard
B212.15. Position the bracket, insert the screw
through the mounting hole of the bracket and
tighten the screw until it is fully embedded.
Slide the cord of the sensor through the slot in the
mounting bracket and use the included nut to secure
the sensor to the mount.

Inowing medium: Do not mount the sensor in or above the lling stream.
Make sure to detect the medium surface, not the inowing liquid.
It is possible to achieve both horizontal and vertical mounting orientations
by rotating the sensor holder to the appropriate angle. The sensor holder
can also be adjusted to compensate for out of plumb conditions allowing the
sensor to be perpendicular to the medium.
