METER STORAGE MODE
All E-Series Ultrasonic meters are delivered in a storage mode so that a meter alarm is not triggered During storage mode,
the empty pipe shows up on the LCD display as an error message, but it will not trigger a meter alarm The meter needs to
sense a full pipe for 24 hours for the meter to go from storage mode to normal operation If installed when the meter is still in
storage mode, the meter will function as expected with the addition of also displaying “err” on the flow rate screen The meter
will display consumption and, if connected to AMR/AMI, will send a reading to the endpoint When the meter is in normal
operation, the meter alarm displays immediately upon detecting the empty pipe condition The alarm clears immediately
after the condition is corrected and the pipe is full Systems that support the additional alarm conditions will be notified that
an empty pipe condition has occurred
METER PRE-INSTALLATION
Take into account the following considerations before you begin an installation:
• Inspect the piping around the meter for suitable conditions The service line, valves, connections and meter must be
watertight Repair the piping system if pipes are corroded or damaged
• Install the meter in the pipeline in a horizontal or vertical position so that the flow arrow on the meter housing points in
the same direction as water flow Registration should be upright and protected from damage, freezing, and tampering
• Position the meter so it is accessible for installation, removal and reading
• Verify that a suitable, electrical grounding wire is properly attached to the upstream and downstream pipe connections of
the meter The grounding wire provides an alternative path for any electrical current that may exist across the opening in
the line
• Close the curb (shutoff) valve to relieve water pressure in the line before starting the cutting operation Provide a high-
quality upstream shutoff valve with a low pressure drop
• When cutting into a new section of service pipe, flush the pipe to clear chips, pipe dope or other plumbing residue
• For the DN15… DN32 meters, the line opening for the meter should match the laying length of the meter, allowing slight
additional space for coupling gaskets The inlet and outlet sides of the meter setting should be axially aligned to
the pipe
• For the DN40 and DN50 meters, the line opening for the meter should match the laying length of the meter For optimal
performance and accuracy, it is also recommended that a minimum of five diameters of straight pipe be installed
upstream of the meter
• The installed meter must not be an obstacle or a hazard to the customer or interfere with public safety
• DO NOT ATTEMPT TO USE ANY METER AS A LEVER OR CROWBAR TO STRAIGHTEN A MISALIGNED METER POSITION.
THIS COULD DAMAGE THE METER.
• DO NOT ATTEMPT TO INSTALL A METER INTO AN OPENING THAT IS TOO LONG BY FORCING THE PIPING INTO PLACE
WITH THE METER'S COUPLING NUTS. THIS WILL CAUSE SERIOUS DAMAGE TO THE THREADED ENDS OF THE METER
AND HOUSING.
• TO AVOID POTENTIAL PROBLEMS, CORRECT ANY IRREGULARITIES IN PIPE SPACING AND MISALIGNMENT BEFORE
PLACING THE METER INTO ITS POSITION.
