Measuring Claw Air Admission
For calibration purposes exact claw air admission is required. Although claw
manufacturers specify products' air admission, it is highly recommended to verify on site
actual performance of each claw.
Measuring Air Admission using Air Gage
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 gage 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” 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 gage 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 occur.
