UFM Series 6
Q.Sonic-plus
Operation and Maintenance
8.3 Exchanging Components
Different parts of the Ultrasonic Flow Meter Series 6 metering system such
as transducers, electronic boards, etc. can easily be exchanged. The digital
programmed pulse shape and pulse identification of the meter is always
identical. Therefore the electronic and transducer products need no
adjustment. This means that re-programming or re-calibration of the meter
after exchanging any identical part of the Ultrasonic Flow Meter Series 6
metering system is not necessary.
Spare parts of the Ultrasonic Flow Meter Series 6 metering system must be
supplied by Elster. After exchanging parts of the Q.Sonic Series 6 metering
system the present “calibration” sealing must be renewed. Please see
Chapter 5.7 Sealing (p.26).
8.3.1 Pressure Sensors Exchange
The meter may be equipped with an optional pressure sensor for internal
use ( see chapter 5.4 Flow Cell Pressure Sensor [p.21]). As the pressure
sensors are specially designed for the Ultrasonic Flow Meter Series 6, they
may only be exchanged with sensors from Elster.
Caution!
Before exchanging any components verify with your local
metrology authority on proper procedures. It may be required that
the operation needs to be witnessed by a representative of the
local authority.
Exchanging of components should only be done with the same
type and model; unless otherwise specified by Elster.
