Operation
To be able to calculate the leakage rate first the pipe capacity must be
determined.
In the first screen of the usage capability test you are asked if you want
to determine the pipe capacity automatically. As alternative you can
insert the pipe capacity manually.
No – continue with 6.3.2 Enter pipe capacity manually
6.3.1
Automatic capacity determination
The capacity determination using the syringe is performed by extracting
a defined capacity (syringe) from the closed pipe system. From the
resulting pressure drop the MFplus calculates the pipe capacity.
Please follow the instructions on the display.
When testing big capacity pipes (>200 Liter) one syringe capacity is not
enough to get enough pressure drop. This will be displayed in a red
pressure value on your screen.
In this case you can raise the syringe volume value using the RIGHT
arrow button and then take additional volume using the syringe.
