Inspecting ultrasonic transmission reliability
after service and repair
Preparation:
• fill a volume measuring unit with water
• remove air
• optimal conditions:
- pressure
- flowrate
- water temperature
> 2 bar
0,1...0,5qp
55+/-5 °C
Checking (with UltraAssistProfi):
• menu „Maintenance“
• command „Amplitude check“
Automatic checking (about 1 minute)
• message „valid/invalid“
• in case of the message „invalid“:
- too much residue in the volume measuring unit
- defective reflectors („small“ meters)
- transducer is defective

Result
• Volume measuring unit of the meter was cleaned, seals were replaced
for new, if required transducer and/or reflectors were replaced
• If required temperature sensors, modules and electronic unit were replaced
• Meter is configured, US-signal level is checked, electronic adaptation to the volume
measuring unit was conducted
• Metrological accuracy of meter is not yet determined
The following steps:
• Flow calibration аnd temperature calibration
• Testing
• Set calibration seal and security label placing
