Ambulance Oxygen Flow Meter: Portable Medical Gas Regulators and Cylinder Valves
Quick Answer: Silver Automation Instruments supplies ambulance oxygen flow meters, portable medical gas regulators, and cylinder valves for oxygen delivery systems. Common flow ranges are 0 to 15 L/min and 0 to 25 L/min with inlet pressures up to 200 bar. Send us your cylinder connection standard, required outlet pressure, and flow range to get a quote.
Ambulance oxygen flow meters are not the same as industrial air flow meters. They operate on low pressure after a regulator reduces high cylinder pressure. If the flow meter or regulator fails, the patient loses oxygen. That is why buyers in ambulance fleets and oxygen supply companies ask for specific connection standards and pressure ratings before they place an order.
Silver Automation Instruments builds flow measurement instruments for process industries. Our main industrial products include Coriolis mass flow meters, electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, oval gear flow meters, thermal mass flow meters, pressure transmitters, and paperless recorders. We also supply portable medical gas regulators and cylinder valves for oxygen service. The main ambulance oxygen flow meter models are SAI-OX-15 and SAI-OX-25.
Flow Ranges and Accuracy for Ambulance Oxygen Flow Meters
SAI-OX-15 covers 0 to 15 L/min. This range fits most adult patients in emergency transport. SAI-OX-25 covers 0 to 25 L/min for high flow masks and special cases. Both units have a standard accuracy of plus or minus 2 percent of full scale. The scale length is 80 mm on the SAI-OX-15 and 100 mm on the SAI-OX-25. The tube is made of polycarbonate with a clear shield. The body is chrome plated brass. Inlet connection is usually CGA 870 or DIN 477. Outlet connection can be a barb for oxygen tubing or a 9/16 inch threaded port.
Portable Medical Gas Regulators That Reduce Cylinder Pressure to a Safe Level
A cylinder valve sees full cylinder pressure. In many countries oxygen cylinders are filled to 150 bar or 200 bar. The portable medical gas regulator must reduce that pressure to a working range. Our SAI-PRG-50 regulator accepts an inlet pressure up to 200 bar and gives an outlet pressure of 3.4 bar. Some ambulance teams need 4 bar or 5 bar for long tubing runs or ventilators. We set the outlet pressure in the factory according to your order. The regulator body is brass with an EPDM or PTFE seat. The pressure gauge is 40 mm with a double scale in bar and psi. The flow meter connects to the regulator outlet through a 1/4 inch NPT or G1/4 port.
Cylinder Valve Options by Country
This is where most orders get delayed. The cylinder valve must match the local gas cylinder standard. A client in the Philippines sent us photos of their cylinder valve and we found it was a DIN 477 number 6 connection. A distributor in Nigeria needed CGA 540 for large cylinders and CGA 870 for portable E cylinders. In Indonesia, we supplied DIN 477 number 6 valves for 1 cubic meter cylinders. In the Middle East, many hospital oxygen cylinders use BS 341 or DIN 477. The thread direction, sealing type, and pressure rating differ
What We Have Seen on Customer Sites
Most engineers skip this part. We have seen ambulance fleets order a flow meter without checking the regulator outlet. Then the flow meter inlet does not fit and they use a temporary hose with clamps. That is not safe for oxygen. Last year a customer in Vietnam ordered 100 units of SAI-OX-15 with DIN 477 connections for their provincial ambulance upgrade. They were replacing old glass tube flow meters that were difficult to read at night. We shipped the flow meters with a white back panel and high contrast black markings.
How to Specify an Ambulance Oxygen Flow Meter
Send us five details. Flow range in liters per minute. Cylinder connection standard. Required outlet pressure. Hose barb size or threaded outlet. Quantity and destination port. If you do not know the connection type, take a photo of the valve and the cylinder neck. Our engineers identify it from the image. In practice, this saves two to three email exchanges. Most systems operate from minus 10 to plus 60 degrees Celsius. If your region is hotter, tell us because the flow tube seal material may change.
Materials and Cleaning
Oxygen service requires clean parts. All wetted parts are free of oil and grease. We clean brass, stainless steel, and EPDM components before assembly. The flow meter body is sealed against dust during storage. In high humidity ports, we add a sealed bag with silica gel to reduce moisture damage during shipping. Tell us if your destination is a coastal city. We will pack with extra protection.
FAQ: Ambulance Oxygen Flow Meter and Portable Medical Gas Regulators
Below are the five questions we receive most often from ambulance fleets and gas distributors.
Does Silver Automation Instruments manufacture ambulance oxygen flow meters?
Yes. We supply SAI-OX-15 and SAI-OX-25 flow meters for oxygen gas. We also supply matching portable medical gas regulators and cylinder valves. We are based in Nanjing, China. We serve ambulance fleets, gas distributors, and medical equipment assemblers.
What cylinder connection standards do you support?
CGA 540, CGA 870, DIN 477 number 6, BS 341 number 3, and AS 2473 type 20. Other standards can be checked against your cylinder photo and gas type.
What is the typical outlet pressure for an ambulance oxygen regulator?
Most ambulance oxygen systems use 3.4 bar or 4 bar. We set the regulator outlet pressure in the factory. High flow masks and ventilators may need 5 bar. Tell us the device pressure range.
Can you supply flow meters for portable oxygen cylinders used in home care?
Yes. The same SAI-OX-15 flow meter works with E type portable cylinders if the cylinder valve is CGA 870 or DIN 477. We also supply small cylinder valves for refill stations and service kits.
