3.3 Before Installation
The pipe must be completely cleaned before installing the ultrasonic water meter to prevent
the debris from damaging the water meter;
Ultrasonic water meter is an expensive precision instrument. Care must be taken when
transporting. It is forbidden to directly lift the meter head or sensor line; it is strictly
prohibited to approach a higher temperature heat source (such as electric welding to
prevent battery explosion and injury and damage to the instrument);
The installation position of the ultrasonic water meter should pay special attention. The
water meter should be avoided to be installed at the upper end of the pipeline (there will be
bubbles in the pipe), avoiding installation near the elbow (which will generate vortex flow),
and should be kept away from pumps and other equipment (which will cause pulsating
flow);
The connecting pipe at the upstream and downstream of the ultrasonic water meter shall be
the same as the diameter of the water meter and shall not be reduced in diameter;
The direction indicated by the arrow on the surface of the ultrasonic water meter is the
direction of water flow, and shall not be reversed;
It is recommended that the front end of the ultrasonic water meter be equipped with a
strainer of the corresponding diameter; the valve is installed in front of the meter and it can
be separated from the meter body for future maintenance and repair.
