6.2. Service and Repair
Direct connection flowmeters do not require routine servicing but can be repaired. The device can
be returned to a recognised BPR Medical Service Centre, details of which can be found at
www.bprmedical.com .
Indirect connection flowmeters should have the hose assembly replaced after four years use or
five years from the date of manufacture. The manufacture date can be found on the device label.
Device life can be calculated by adding 7 years to the date of manufacture.
Disassembly, repair or reassembly must be carried out by a suitably qualified person working in a
controlled environment.
7. Specification
Specification Value
Flow Scale 0 – 15 l/min
Inlet Pressure Range
Model specific between 370 – 550 kPa
Note: The flowmeter is able to operate safely within the pressure range 370 kPa
to 550 kPa, but the flowmeter will only deliver accurately when connected to an
input pressure as shown on the device. Any input pressure other than shown on
the device will result in flow rates different from the flow settings
Supply Pressure Range
Minimum 370 kPa
Maximum 550 kPa
