Oxygen Flow Meters and Oxygen Flow Meter Price: Medical and Welder Gas Regulators

Quick Answer

Oxygen flow meters measure gas flow for medical breathing systems, cutting torches, and welding rigs. Medical tube type flow meters typically cost 15 to 65 USD for basic models and 80 to 220 USD for chrome plated units with needle valves. Welding oxygen regulators with flow meters range from 25 to 90 USD based on inlet pressure, flow range, body material, and connection standard.

Medical Oxygen Flow Meters: What Specs Actually Matter

Hospitals and clinics in Vietnam, Indonesia, and Nigeria buy medical oxygen flow meters for ward beds, ICU trolleys, and ambulance cabinets. The most common inlet connection is a DIN 13260 medical gas probe or a 9/16 inch UNF thread. Flow ranges are small. A standard ward unit covers 0 to 15 L/min. Pediatric and neonatal units often go down to 0 to 3 L/min with a finer adjustment knob.

Most engineers skip this part. The tube must handle 100 percent oxygen without cracking. Polycarbonate tubes are common. Brass or chrome plated bodies resist corrosion in humid coastal clinics. Some buyers in the Middle East ask for all metal bodies because of dust and high room temperature. Silver Automation Instruments supplies both metal and plastic medical oxygen flow meters with outlet barb or Christmas tree connectors.

Welding Oxygen Flow Meters and Regulator Sets

Welder gas regulators control oxygen flow from cylinders at 200 bar or 150 bar down to working pressures of 2 to 4 bar. A simple oxygen regulator with two gauges and no flow meter costs less. A flow meter regulator set includes an inlet gauge, outlet gauge, pressure relief, and a clear flow tube calibrated from 1 to 25 L/min.

We have seen this on customer sites many times. A welding workshop in Peru used a cheap argon regulator for oxygen because it was available. That caused internal oil ignition risk. Oxygen regulators must be oil free and cleaned for oxygen service. The label should say OXYGEN or O2. Silver Automation Instruments sells oxygen cleaned regulators with brass body and polycarbonate flow tubes for cutting torches, brazing, and preheating.

Last year a customer in Vietnam asked us for 200 medical oxygen flow meters with DIN probes for a district hospital project. Another buyer in Ghana needed 50 welding oxygen regulators with CGA 540 connections for a steel fabrication yard in Tema. We shipped both orders from Nanjing in two separate consignments. The labels and cleaning certificates were different because medical and industrial oxygen codes are not the same.

Oxygen Flow Meter Price Ranges by Type

Price depends on body material, flow range, connection type, and whether the unit is medical grade or industrial grade. Basic medical oxygen flow meters with plastic body start around 12 USD for bulk orders of 100 units or more. A mid range chrome plated medical unit costs 25 to 40 USD. A welding oxygen regulator with flow meter starts at 22 USD for a single stage unit. Twin gauge heavy duty models for cylinder manifold use range from 45 to 90 USD.

For a desalination plant or wastewater lab using oxygen for aeration and gas analysis, you may need a thermal mass flow meter or a rotameter with a 4-20 mA HART output. These are not standard medical or welding devices. Silver Automation Instruments can supply oxygen thermal mass flow meters with DN15 to DN50 process connections and display total flow in kg/h or Nm3/h. Prices for these industrial units are higher, usually 300 to 900 USD. ATEX Zone 1 options are available for gas blending skids and liquefaction plants.
