Installation Requirements
1. Ensure that the connecting
pipes are aligned (Figure 1).
2. Check for the proper distance
between the pipe unions to
avoid mechanical stress.
3. The meter may be installed in
any orientation.
There are no straight pipe
requirements upstream or
downstream of the Sonata.
4. Always use new gaskets and ensure
that the coupling nut surfaces are
clean.
Installation Notes:
•Do not install the meter on the
suction side of a pump.
•Avoid exposing the meter to
excessive vibration.
•Supporting the pipeline on both
sides of the meter is recommended.
Installing the Sonata
1. Unpack the Sonata. Install/assemble
accessories as needed, if supplied
(strainer, NRV)
2. Note the proper flow direction as
indicated on the meter. The Sonata
is a bi-directional flow meter and will
also measure reverse flow.
3. Install new gaskets in the coupling
nut.
4. Place the meter in position and
carefully tighten the coupling nuts by
hand. Make sure each coupling nut is
smoothly screwed onto the meter
threads
Use a wrench to tighten the coupling
nuts to a minimum torque setting of
10 lb-ft up to a maximum of 35 lb-ft.
5. Once installed, open the upstream
valve to allow water to fill the meter
and piping.
6. Open a downstream valve to flush all
air out of the pipeline.
7. Close the downstream valve and
verify that there are no leaks at the
coupling nuts.
After the air is purged from the pipeline,
the “No Measurement” alarm indication
on the LCD will turn off and the Sonata
will then be fully functional and ready for
operation.
Sonata’s RF transmission, alarms, and logs
are activated shortly after water
consumption begins.
Disposal
