Double Oxygen Flow Meter: Two-Patient Healthcare Facility Cylinder Delivery Outlets
Quick Answer: A double oxygen flow meter with two-patient healthcare facility cylinder delivery outlets splits one oxygen cylinder supply into two independent flow channels. It lets a clinic or emergency unit serve two patients from one cylinder without changing the manifold. Silver Automation Instruments can supply the flow measurement and control panel with oxygen clean materials and optional 4-20 mA HART output.
What the Device Does on a Cylinder
One high pressure cylinder connects to the panel inlet. The panel reduces and splits the gas stream into two outlets. Each outlet has its own flow adjustment valve and flow meter. Nurses or biomedical technicians set each flow rate in L/min. The two channels operate separately. One patient can receive 5 L/min while the other receives 10 L/min from the same cylinder. This setup is common in small hospitals, rural health posts, and emergency rooms across Southeast Asia, Africa, and the Middle East.
Flow Ranges, Accuracy, and Repeatability
Most double oxygen flow meters for cylinder delivery use a range of 0 to 15 L/min per outlet. Some panels go up to 0 to 25 L/min for high flow oxygen therapy. Accuracy is usually ±1.5 percent full scale or ±1.0 percent of indicated flow for electronic versions. Repeatability needs to stay within ±0.5 percent full scale. Here is the thing. A nursing team changes flow rates often. The valve and float must return to the same set point every time. We have seen this on customer sites many times.
Wetted Materials and Oxygen Cleaning
Oxygen service is unforgiving. Brass, stainless steel 316, and aluminium are common body materials. Avoid polymer parts that can degrade in pure oxygen. All wetted parts must be oxygen cleaned before assembly. No oil, no grease, no hydrocarbon residue. A proper panel supplier provides a cleaning certificate. Ask for this document because many biomedical inspectors check it. Silver Automation Instruments uses oxygen cleaned procedures for gas flow metering panels.
Inlet and Outlet Pressure Data
Inlet pressure at the cylinder regulator often ranges from 3 to 6 bar. The double outlet flow meter works best when downstream pressure stays low, around 0.3 to 0.8 bar at each patient outlet. Connections are commonly G1/4 or 1/4 inch NPT. Ambient operating temperature should be 0 to 50 °C. Housing protection IP54 is enough for indoor ward use. If the panel goes into a mobile ambulance or field hospital, specify stainless fittings and a stronger housing.
Monitoring and Electrical Output Options
Basic mechanical panels do not transmit data. Man
Field Notes from a Customer Site
A customer in the Philippines asked us to configure a two-patient oxygen cylinder panel for a rural health unit. They ran one 50 L cylinder. Two beds needed oxygen at the same time. The panel had 0 to 15 L/min per outlet, brass body, and oxygen cleaned threads. They added thermal mass flow meters later because the regional health office wanted digital flow logs. This is a common upgrade path in Southeast Asia. We have seen the same request from a clinic in Nigeria in 2024.
How to Specify the Right Double Oxygen Flow Meter
Send us these details: inlet pressure in bar, required flow range per patient in L/min, outlet connection size, number of cylinders used per day, and whether you need 4-20 mA output. Also state if the panel is for wall mounting or trolley mounting. We check the wetted materials against your oxygen purity and cleaning standard. Then we quote a panel with two channels and the correct valve type. Contact Silver Automation Instruments at Tel +86-25-68650347, Whatsapp +86-25-52155837, or WeChat +86 15365082610.
FAQ: Double Oxygen Flow Meter Two-Patient Cylinder Delivery
What is a double oxygen flow meter for two-patient cylinder delivery?
It is a panel that connects to one oxygen cylinder and provides two separate flow control outlets for two patients.
What flow range do these panels typically offer?
Most panels offer 0 to 15 L/min per outlet. Some versions offer 0 to 25 L/min for high flow applications.
Can I get an analog or digital output for patient flow monitoring?
Yes. Silver Instruments can install two thermal mass flow meters with 4-20 mA HART or RS485 Modbus output on the panel.
What materials are safe for oxygen service?
Brass, stainless steel 316, and aluminium are common. All wetted parts must be oxygen cleaned with no oil or grease residue.
