10.1 Gas Velocity Measurement with Optional Vane Anemometer
Connect the vane anemometer to the Comms port at the top of the instrument.
Locate a suitable gland or bung on the pipework and insert the anemometer.
When the anemometer is as far into the gland as possible without opening the tap, open the gas tap.
Finally, push the anemometer into the gland far enough to ensure that the impeller is in the centre of the gas pipe.
Now press the “Sample” key to begin measuring the flow in the pipe.
