Dairy Farming
1. Installation of the new milking parlor, including the SmartFlow milk meters.
2. Zero-point test of the SmartFlows to determine the setpoint of the Float (see Zero-point test (page 24)).
3. Calibration of the SmartFlows by carrying out the milk test (see Milk test (page 25)).
4. Annual validation check of the SmartFlows by carrying out either the zero-point test (Zero-point test (page
24)) or the statistic test (Statistic test (page 25)).
When a component of the SmartFlow is repaired or replaced, for instance the Float, the SmartFlow needs to
be calibrated and validated again by executing step 2, 3 and 4.
4.2.1 Zero-point test
A zero-point test is a static measurement that measures the raw sensor height of a Float in a known setting. The
zero-point test is carried out at installation of the SmartFlow or after changing the Float. Furthermore, the zero-
point test can be done at the annual validation check.
Start the zero-point test:
1. Decide to start the zero-point test for (a) separate SmartFlow device(s) or for all at once.
2. Click the Start Zero-point test button in Velos.
Execute the zero-point test in the milking parlor:
1. Decouple the milk inlet tube from the milk claw.
2. Install an air compressor on the vacuum inlet (max. 300 mbar).
Warning
Do not exceed this pressure to avoid damage to your installation!
3. Pour drinking water in the milk inlet tube (minimum flow of 5 L/min and for at least 5 seconds)
The temperature of the drinking water must be ca. 10 °C (50 °F)
4. Wait for at least 3 minutes.
5. Repeat step 3 and 4 four times
The total zero-point test session consists of five consecutive runs, with 3-minute intervals.
6. De-install the air compressor.
7. Reconnect the milk inlet tube to the milk claw.
Zero-point test results:
1. Stop the zero-point test by clicking on the Stop zero-point test button in Velos.
Velos will show the zero-point test results.
2. At installation: Always click the Write button to store the zero-point test results in the Velos database.
3. Annual validation check: When the zero-point test is completed, the result is shown immediately.
a. Pass: New result of zero-point test is within range: No further action is needed, the result is stored and
can be checked in the report.
b. Fail: New result of zero-point test is NOT within range: Check the SmartFlow in the milking parlor for
technical issues.
1. The SmartFlow is technically fine: Store the new zero-point test result and calculate a new
calibration value using the milk test (see Milk test (page 25)).
2. The SmartFlow is technically not fine: Fix the SmartFlow. Next perform a zero-point test and
recalibrate using the milk test (see Milk test (page 25)).
When the zero-point test is completed, the results are stored in the "Zero point test" report. Send the report to
your ICAR Member Organization.
