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.

0 – 15 l/min

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

Minimum 370 kPa
