Flowmeters shall be supplied with gas-specific probes and only attach to the corresponding medical gas terminal unit, it accurately measures flow at 0-15Lpm even at variant inlet pressures. Accuracy is fulfilled within 10% to attain maximum efficiency for the patient and environment.
Each flow meter is calibrated at 50 psi inlet pressure
The Flowmeter shall be manufactured to EN 13220:1999 and ISO 15002:2008 and constructed from a chromium-plated brass body, inner and external tube in crack-resistant polycarbonate and stainless steel ball. Other pieces shall be in brass.
Constructed from polycarbonate, Sterilisation should be conducted in an autoclave on a 25 min cycle at 121 ºC, 1.3 kPa (max. 40 times). Before sterilisation remove the tube and diffuser and consequently disposed.
Manufactured under BS EN 13485 Medical Devices: Quality Management Systems.
