1Brief Introduction
⚫The ultrasonic water meter is a new type of intelligent all-electronic meter. It
integrates measurement and display to achieve accurate measurement with a
minimum flow of 0.01 m3/h.
⚫Achieve multi-angle installation and minimize the pipe pressure loss.
⚫Dedicated to household measurement in residential quarters
⚫Connect to the GSM wireless concentrator produced by our company, using GSM mobile
public network for data transmission to form a wireless monitoring system. It automatically
reports abnormal status.

6Installation and Connection
6.1 Installation and Connection Requirements
Install the meter in strict accordance with the requirements. Strictly forbidden to self-remove
meter.
Before installing the water meter, remove dirt and other rubbish in pipeline to avoid
malfunction of water meter.
Leave enough space for meter and connectors installation.
To ensure the measurement accuracy, the reserved length space is the following. In the front of
meter, the length space is over 10 times of diameter. Behind meter, the length space is over 5
times of diameter. Avoid the interference from elbow pipe, tee, cone pipe and pump. If there is
a reduced diameter pipe installed before meter, the reserved length space will be over 15 times
of diameter; if a 90° elbow, the length must be 20 times of diameter; if a half-opening valve,
the space is over 50 times of diameter.
*D=diameter
LF= the length in the front of meter
LB=the length behind meter

a half-opening valve in the front of meter
LF > 50D
Table 6-1 Special Cases and Reserved Pipe Length
Avoid damage to the water meter caused by impact or vibration of the meter installation
environment, and avoid damage caused by excessive stress from pipes and fittings. If necessary,
please install the water meter on the base or bracket.
Prevent extreme water temperature, extreme temperature, and external environment corrosion
to water meter damage.
Avoid cavitation, surge and water hammer.
6.2 Meter Installation
➢The installed pipe must be filled with water. Install the meter on a vertical pipe in which the
liquid flows upwards or diagonally upwards. If not, select a horizontal pipe. Try to AVOID
installing the meter in a vertical pipe with the liquid flowing downwards or diagonally
downwards.
➢AVOID installing meter at the highest point of pipeline to prevent the air bubbles accumulated
7
and interfere with measurement.
Figure 6-1 Installation Method (1)
➢Reserve a space at the water pipe for meter installation.
Figure 6-2 Meter Installation (2)
➢Concentrically align meter with pipe. Use a wrench to connect the pipe blade to meter thread
and tighten it.
