3 Instructions
3.1 LCD display instructions (shown on below)
1. put the manget touch the magnetic control key above the date of the water meter
panel，The display menu will scroll between A0-A1-A2-A2-A3-A4; the
short-track magnetically controlled key will scroll within the same menu.
2. Main display menuA0：Accumulated flow （m3）、negative cumulative flow（m3）、
instantaneous flow（m3/h）Three items Display cycle switch.
3.Main display menuA1：Accumulated flow（m3）
、instantaneous flow（m3/h）
、water
temperature（℃）
、cumulative running time（h）
、fault cumulative time （h）
。This
is the test interface, the cumulative flow display range: 999.99999, instantaneous flow
for 10 seconds for 0,then shows the instantaneous flow again,then the cumulative
flow is automatically cleared to facilitate the testing.
4. Main display menu A2: factory number, current date, real time, caliber / battery
voltage, baud rate / program version number.
5. Main display menu A3: The first 24 months of monthly traffic values, month and
monthly cumulative flow between the automatic display.
6. Main display menu A4 (alarm and event log):
LOSS-BATT: low battery voltage or battery power-down
information record;
EMPTY: empty pipe information record;
-: Negative traffic is recorded;
MAX: maximum flow is greater than Q4 record;
MIN: minimum flow rate is less than Q1 record;
MAX: Temperature record with a maximum temperature exceeding 30 °

5 Precautions
(1)The water meter installation must meet the GB / T 778.2 installation requirements,
the cooper inline pipe should 5 times-diameter distance to the upstream and 3
times-diameter distance to the downstream.
(2)The piping flow should be in the same direction as the logo arrow on the water
meter
(3) Wired communication of the ultrasonic water meter M-BUS wiring without
polarity requirements, but must ensure that the wiring is solid and reliable, and
pay attention to do waterproof moisture treatment. Line joints do not bear the
tension, or easily to pull off joints caused by communication disconnect.
(4) Wireless communication of ultrasonic water meters should not be installed in
strong lines and other highelectromagnetic radiation near the source, otherwise it
will affect the reliability of wireless signal transmission.
(5) Ultrasonic water meter is a measuring instrument, must be in accordance with
national standards for ultrasonic water meter for regular verification, and replace
the battery before lifespan ran out.
(6) Without the permission of manufacturer, no one shall dismantle the maintenance
ultrasonic water meter, otherwise the warranty service shall be discharged.
6 After-sales service
Free warranty: 2 years
The warranty start time is based on the order contract time or the date of manufacture
of the product.Original seal damage is not warranty.Due to improper use and
maintenance of the product caused by failure or damage is not warranty.Damage
caused by force majeure, such as war and natural disasters. won’t warranty.
FCC Warning
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment. This equipment has been tested and
found to comply wit h the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are desi gned to provide reasonable protection against harmful interference in
a residential installation. T his equipment generates uses and can radiate radio frequency energy
and, if not installed and us ed in accordance with the instructions, may cause harmful
interference to radio communications . However, there is no guarantee that interference will not
occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interfere nce by one or more of the following measures:
-Reorient or relocate the receiving antenna.
