The model Flowmaster 250DL portable ow and
pressure tester measures the available pressure
and ow at the service point while recording the
measurement points in the internal data logger for the
creation of veriable reports.
There are no moving parts in the sensors, leading to
high reliability. The Flowmaster 250DL measures static
pressure, residual pressure, instantaneous ow, and
total ow.
The integrated data logger records ow and pressure
readings at one second intervals and stores these in
internal memory. The log les are uploaded to your PC
through the USB port where the powerful graphing
software greatly simplies report writing.
The Flowmaster is now used by most UK and Irish
re services and has been exported to 50 countries.
The Flowmaster meets the requirements of the JOIFF
standard, ‘Guideline for the testing of re hydrants’.
