TSI Instruments Flowmaster 250DL - STATIC PRESSURE MEASUREMENT; FLUSHING PROCEDURE

4.3 STATIC PRESSURE MEASUREMENT
1) Attach Flowmaster to standpipe.
2) Attach blank plug. Ensure bleed valve is open.
3) Crack open the hydrant slowly. All air will be
expelled from the standpipe when water begins to
drain from the bleed valve. Close the bleed valve.
5) When reading is taken, close hydrant fully.
4) Read static pressure (in bar).
6) Open the bleed valve to exhaust pressure from
the meter and standpipe. Remove the blanking plug
and progress to ow test.
