WARNING: A voltage potential between the ground wire of the unit and the
ground of other equipment can lead to electrolytic corrosion. Always ensure the
grounding system provides an equipotential between the transmitter and the
earthing ground connection. Avoid using the power system protective ground since
this will often have a signicant potential difference to the transmitter ground.
Also, note that dissimilar metals in the ground system may cause electrolysis
corrosion of the transmitter or other components in the ground system.
During installation, connect a voltmeter or ammeter between the shield ground
wire and the grounding connection. If there is a measurable voltage or current
electrolytic corrosion may be a serious possibility. If there is a potential
difference then some isolation system will be required. Improper grounding
may lead to damage or poor function.

Ultrasonic Pro™ Distance/Level Sensor
See Water’s Ultrasonic Pro™ Level Sensor combines an ultrasonic sensor,
temperature sensor, ultrasonic servo circuit, and transmission circuit; It also uses
SMD components and ASIC. The shell is made of quality NLEPF synthetic material
with solid texture and good acoustic characteristics. The body is waterproof and
can be used in a wide variety of applications. The Ultrasonic Pro™ Level Sensor is
also easy to install and simple to maintain.

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 angle of the ultrasonic wave. When measuring the object level, the feeding
hole should be avoided to prevent interference with the ultrasound echo.
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.

Inowing medium: Do not mount the sensor in or above the lling stream. Make
sure to detect the medium surface, not the inowing 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.
