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®
FLOWMETER RMA-22-SSV.
Follow the procedure described below if an air gauge is available to ensure accurate
results.
1.
Remove the milk and pulsation hoses from the cluster as illustrated in Figure 12
below.
2.
Insert four plugs into the four milking cups.
3.
Clean the air orifice in the cluster.
4.
Connect the air gauge as illustrated in Figure 12 below. The lower port of the air
gauge is connected to the claw via a short 5/8 inch hose connector. The top outlet
port of the air gauge is inserted into the milk hose leading to the milk meter body.

5.
When the gauge is securely connected as described, press
on the display panel in
order to open vacuum to the cluster.
6.
Check and seal any vacuum leaks at connections in the air gauge and cluster.
7.
Block the air orifice with your finger to verify that the only air intake allowed is via the
air orifice. The ball in the gauge should fall to zero if no air leakage occurs.
8.
Hold the air gauge in a vertical position and allow air admission via claw orifice. Write
down the air intake the gage measures. This measurement will be used for calibrating
the “G” parameter value as described below.
