  • Page 3: Milk Meter Calibration

    7 Milk Meter Calibration Afimilk MPC is calibrated in the factory to ensure milk measurement results within the required accuracy ranges. However, since installation environment may affect milk measurement accuracy, Afimilk MPC requires calibration at installation. Three calibration procedures are described in this chapter: 1.

  • Page 4: Electrodes Calibrating Procedure

    7.1.1.1 Electrodes Calibrating Procedure At each meter, calibrate the holding and operating electrodes in one single procedure, as described below: Holding (middle) electrode: Calibrate electrodes as follows: 1. Carefully unlock the bottom clasp of the body and remove the lower cover with the inner valve cylinder connected to it.

  • Page 5: Reviewing Calibrated Values Of Electrodes

    Operating (top) electrode: Connect the 100Ω resistor between the Operating (top) electrode and the Common (lower) electrode. 1. Press H### is displayed ( represents the calibration value). 3. Press a second time to calibrate the electrode. AdJt appears. 4. The electrodes have been calibrated. 5.

    from 6 to 12 liters per minute. Afimilk MPC calibration neutralizes air intake influence. Calibration is required whenever clusters are changed and/or when air vented liners are used. Calibration procedure adjusts the value of parameters "G" ( Air admission Adjustment and "H"...

  • Page 7: Measuring Claw Air Admission

    7.2.2 Measuring Claw Air Admission For calibration purposes an exact claw air admission measurement is required. Although claw manufacturers specify products' air admission, it is highly recommended to verify actual performance of each claw on-site. This method incorporates the use of an air gauge to measure Air Admission. Afimilk recommends an air gauge manufactured by Dwyer Instruments Inc., the RATEMASTER®...

    o Press to confirm. o When done, press twice to exit editing mode. 7.2.5 Adjusting the G and/or H parameter value via communication The easiest way to adjust G and H parameters values is via the AfiControl interface. As explained below, you may change the value of each milking point individually OR set a uniform value to ALL the milk meters.

  • Page 10: Accuracy Adjustment

    7.3 Accuracy Adjustment AfiMilk MPC milk meters are supplied with default adjustment calibration values. After the initial setup (see adjustment per air intake explained above) inaccuracies of milk measurements vs. bulk tank OR in specific milk meters can be found; therefore parameters values may need further adjustment.

  • Page 11: Use Of Bulk Tank And Fine Adjustment And References By Water Test

    7.3.1 Use of bulk tank and fine adjustment and references by water test Bulk tank calibration is used for adjusting average accuracy of all the milk meters together. This procedure is performed by calculating the parlor difference between the milk measured by the milk meters and the bulk tank total.

  • Page 12: Equipment And Water Test Preparation And Description

    IMPORTANT Make sure you work accurate with collecting all the data you need. This includes i.e. missing data due to missing cow identification, milk thru the meter but not in the bulk tank and milk substraction out of bulk tank. To adjust the parameter valua follow the procedure in paragraph Adjusting G and/or H...
  • Page 13 A nipple with air inlet 1mm in diameter should provide air intake of 10 ± 1 LPM. Air inlet nipple should be connected no closer than 50cm from the water sucking port. Hoses and connectors to set-up the test system – the milking bucket should have an inlet port of 20mm or more.
  • Page 14 Testing the air intake To test the air inlet an air flow gauge is used To perform the test, place the air flow gauge in place of the water flow gauge. Block the water inlet to allow air flow through the air inlet alone. Open the vacuum valve and register the air intake measured.

  • Page 18: Statistical Accuracy Calculation

    o The Milk Meter reading should be taken after the last dump of milk (milk dump after removal). o For each reading, list milk meter reading vs. actual milk weighed. o At least three valid readings are required for calculating milk meter accuracy. To ensure proper measurements, see that the following restrictions are kept: o The collecting bucket must be placed below the meter outlet port.

    To adjust the parameter valua follow the procedure in paragraph Adjusting “G” and/or “H” parameter value or via the AfiControl interface mentioned in paragraph Adjusting the “G” and/or “H” parameter value via communication. During initial calibration it is the aim to adjust each meter around 0% deviation, while this is the base for setting the reference values with water.

  • Page 21: Milk Test For Calibration (Two Sessions) And References By Water Test

    7.3.3 Milk test for calibration (two sessions) and references by water test This test is performed by collecting the milk each cow gives into a bucket, measuring it and comparing it to the reading of the milk meter. Then, statistical deviation calculations are done to indicate the accuracy level of the device.

  • Page 22: Statistical Accuracy Calculation

    o The hose connecting the Milk Meter to the bucket is situated correctly in a downward slope towards the bucket. o The hose connecting the Milk Meter to the bucket has no pulling or pushing pressure on the outlet of the Milk Meter. 7.3.3.2 Statistical Accuracy Calculation After scaling milk weights for all the milk meters in the parlor, statistical accuracy calculation is performed for each milk meter.

  • Page 23: Setting The Reference Value By Water Test

    If the result is negative (Milk meter reading is lower than the actual weight), the calculated adjustment value needs to be added to the value of . If the adjustment is positive, the calculated value needs to be subtracted from the value of General adjustment calculation →%Dev X (–5) = Adjustment value Example: if the actual value of H in the milk meter is 37 and the measured deviation -4% (Milk meters show 4% less than actual weight), modify the “H”...
