6.2.2 Testing Installation
The flow cell is always hydrotested in-house at the correct hydrotest
pressure before the transducers are installed on the ultrasonic flow meter.
Herewith all welding of the flow cell is checked. When a Series 6 UFM is
installed in a pipe line, it is no longer possible to hydrotest the pipeline.
Water can be trapped between the housing and the transducers, causing the
meter to have difficulties measuring.
Before pressurizing, check all pressure points on the meter. If necessary
remove the cover caps to have a clear view of the entire pressure point,
particularly when an adapter is fitted on the meter body.
To avoid possible injury, make sure the lifting equipment is
suitable for the weight of the Ultrasonic Flow Meter Series 6.
Always use the lifting lugs and make sure lifting equipment is
certified and shows no damage or wear.
Eyebolts must be inspected before each use and used according
to the manufacturer’s specification.
Be Aware!
Special attention needs to be taken when the UFM Series 6
Q.Sonic
plus
has to be installed in accordance with MID. See
Chapter 12.5 Installation Requirements (p.64).
For FM Approved and CSA Certified UFMs also see their
respective Control Drawings and particular installation remarks in
the UFM Series 6 Safety Instructions ( listed in Appendix I –
References).
