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 signicant 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.
