Operation of the Pneumatic Test Kit
Reading the Flow Meter
A float type rotameter (variable area) flow meter is fitted to the
pneumatic test kit. The correct point on the float to take the flow
reading is at the top edge of the float, as shown.
Also ensure that the float is viewed directly from the side, as shown.
Taking the reading looking down on the float will add inaccuracy to
the measurement.
General Instructions
1. Ensure that the pneumatic test kit is mounted on a stable, level
surface. Check that the back pressure gauge reads zero, and
adjust using the zero adjust screw if required.
2. Ensure that the sample pump battery is fully charged. Run the
sample pump for five to ten minutes prior to carrying out pump
compensation or sample media back pressure checks.
Sample Pump Compensation Verification
Refer to the sample pump instruction manual or SKC Ltd for pump compensation specification.
1. Connect the inlet hosetail of the pump to the pump connection hosetail on the pneumatic test kit using a
length of flexible tubing.
2. Ensure that the back pressure bypass valve is in the bypass (down) position.
3. Turn on the sample pump and set the desired flow rate as detailed in the pump instruction manual. Note
the reading on the pneumatic test kit flow meter.
