7  Maintenance, service and repair  

7.1 

Introduction 

The Ultrasonic Flowmeter Series 6 ultrasonic gas flow meter contains no moving parts. The 
transducers and internal pressure sensor are the only components that are in contact with 
the  gas  medium.  The  materials  used  for  the  transducers  are  selected  for  the  measuring 
conditions that were clearly specified for the instrument. As a result the transducers and the 
electronics are virtually maintenance free. However, Elster NV/SA recommends inspection 
of  the  Ultrasonic  Flowmeter  Series  6  with  the  software  packages  ‘SonicExplorer’  at  regular 
intervals (e.g. monthly). In case of degradation of the meter, appropriate measures can be 
taken on time. 

For  detailed  information  about  maintenance,  please  refer  to  operation  and  maintenance 
manual (doc. code: 22.100.200.002.02/2 last valid revision).  

7.2 

Exchanging components 

Different  parts  of  the  Ultrasonic  Flowmeter  Series  6  metering  system  like  transducers, 
electronic boards, etc can  be exchanged easily. 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  Flowmeter  Series  6  metering 
system is not necessary. 
 
Spare  parts  of  the  Ultrasonic  Flowmeter  Series  6  metering  system  must  be  supplied  by 
Elster NV/SA. After exchanging parts of the Q.Sonic Series 6 metering system the present 
“calibration” sealing must be renewed, see the chapter 4.7. 

 

 

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. 

 

 

 

Warning! 

Exchanging  of  components  should  only  be  done  with  the  same 
type and model; unless otherwise specified by Elster NV/SA. 

 

7.2.1. 

Pressure sensors exchange 

The  meter  might  be  equipped  with  an  optional  pressure  sensor  for  internal  use  (see 
chapters 4.4). As the pressure sensors are specially designed for the Ultrasonic Flowmeter 
Series 6, they may only be exchanged with sensors from Elster NV/SA.
