3 Ultrasonic Flow Meter Series 6
3.1 General
The UFM Series 6 Q.Sonic
plus
is a sophisticated, multi-path ultrasonic gas
flow meter manufactured by Elster. It has been specifically designed for
custody transfer measuring applications that demand a high degree of
accuracy and reliability. It can be extended with an extra functionality
whereby the flow meter has the possibility to convert the measured line
volume to standardised volume, mass or energy.
The Ultrasonic Flowmeter Series 6 contains 2 type plates:
• Main plate: Provides information on mechanical design conditions as well
as flow related information such as meter factor and range
• SPU type plate: Provides information on applicable hazardous area
approval.
Ensure the meter never operates outside the limits stated on the type plates.
Any discrepancy between the type plates should be reported to Elster or
your local agent immediately. Please refer to Chapter 5.6 Labels and
Nameplates (p.22) for more information.
Improper use of an UFM Series 6 may not only result in
unreliable performance, but may lead to hazardous
situations.
Please refer to the type plates, located on the meter for the
correct operating conditions. Never use the meter outside these
limitations!
