Page 20: Transducers
System Description 5.3 Transducers The ultrasonic signals required for the flow measurement are generated and received by ultrasonic transducers. Piezoelectric transducers employ crystals or ceramics that are set into vibration when an alternating voltage is applied to the piezoelectric element. The vibrating element generates sound waves in the gas. -

Page 48: Info
Operation This is useful if the process conditions differ significantly from the conditions during the calibration process since both high pressure and high temperature results in an increase in the tube cross-section and a change in path lengths and angles. Please Note: k-factor GeomCorr. - Page 49 Outcome can be OK or FAIL. If a FAIL is encountered, the selftest should be done again. If it continues to fail, contact Elster or your local agent. SW versions (internal) – Herewith all software versions and their matching checksum in the electronics can be read.

Page 50: Maintenance
As a result the transducers and the electronics are virtually maintenance free. However, Elster recommends inspection of the UFM at regular intervals, for example weekly or monthly evaluations. In case of deterioration of the meter, appropriate measures should be taken before a serious failure occurs. -
Page 51: Performance
Maintenance The sample rate is programmable to be anything between 1 and 100Hz. However, the actual sample rate may be lower than the programmed value since, particularly with large size meters, the travel times of the ultrasonic pulses in the gas do not allow for the programmed sample rate. The UFM will then adjust the sample rate to the highest possible value. -
Page 52: Presentation Of Agc-Levels And Agc-Limits
The meter operates reliably if the angle is between -20° and +20°. If the indicated swirl angle exceeds these values please consult Elster for support. Page 52 of 68 Operation and Maintenance UFM Series 6 Q.Sonic-plus... -
Page 53: Exchanging Components
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... -
Page 54: Temperature Sensors Exchange
[p.21]). As the temperature sensors are specially designed for the Ultrasonic Flow Meter Series 6, they may only be exchanged with sensors from Elster. As the temperature sensor only measures the flow cell temperature and is not in contact with the gas in the pipe, exchanging can be done under pressure. -
Page 55: Spu Exchange
An SPU exchange will not affect the measuring characteristics and accuracy (and as a consequence the calibration) of the UFM. However if the board is sealed after calibration, please contact Elster or your local representative before proceeding with the exchange. - Page 56 Maintenance Ultrasonic Flow Meter Series 6 Exchanging Boards at the Rear Compartment of the SPU Both documents are listed in Appendix I – References.
