Invacare Pediatric Flow Meter: Low-Flow Medical Gas Regulators for Precise Neonatal Care Wards
Quick Answer: The Invacare pediatric flow meter is one of the low-flow medical gas regulators built for oxygen and medical air delivery in neonatal care wards. It lets clinicians dial in small flow rates from 0 to 1 L/min or 0 to 3.5 L/min, often in 0.125 LPM steps. Silver Automation Instruments helps hospital biomedical teams, contractors, and instrument buyers compare low-flow gas meters, inlet connections, and spec sheets for non-clinical test benches and OEM equipment.
What This Flow Meter Does in a Neonatal Ward
A newborn in respiratory distress often needs a low and steady gas flow. In a ward in Manila or a public hospital in Peru, nurses and biomedical staff rely on a flow meter that can hold 0.1 L/min without drift. The Invacare pediatric flow meter mounts on a 50 psi oxygen or air outlet, often with a DISS, Chemetron, or Ohmeda style probe. The nurse adjusts the needle valve and reads the ball or bobbin height inside the Thorpe tube. Most neonatal units choose the 0 to 1 L/min or 0 to 3 L/min range because higher ranges make fine adjustment harder.
Here is the thing. Neonatal oxygen delivery is not forgiving. A small error of 0.2 L/min can matter for a 900 gram infant. That is why the flow meter body has a fine thread valve, a clear polycarbonate tube, and markings that are readable from a short distance. We have seen this on customer sites many times when a general adult flow meter was installed by mistake and the reading was too coarse.
Key Technical Details That Affect Selection
Buyers in Southeast Asia, Oceania, Latin America, Africa, and the Middle East often ask us which low-flow gas regulator fits their existing wall outlet. Most problems come from two points. The inlet connection does not match the gas station. The flow range does not match the clinical task. You need to confirm both before purchase.
Common technical specs for a pediatric medical gas flow meter include a flow range of 0 to 1 L/min with 0.125 L/min graduations, a chrome plated brass body, a polycarbonate outer tube, and a hand tight DISS nut. Some versions cover 0 to 3.5 L/min for air and oxygen mixers. Inlet pressure is usually 50 psi from the hospital gas pipeline. Outlet barbs accept 5 mm or 6 mm ID tubing. Gas specific connections include CGA 540 for oxygen cylinders, CGA 590 for air cylinders, and DISS 1240 for low pressure oxygen wall outlets in many countries.
Most engineers skip this part. They order a flow meter by brand name but forget that the wall probe is country specific. A biomedical technician in Hanoi asked us a spec question last year. He had a pediatric flow meter with a Chemetron probe but the old wall outlet was a DISS fitting. We pointed out the mismatch before he ordered a replacement. The downtime in the neonatal bay was avoidable.
What We Supply and What We Do Not Supply
Silver Automation Instruments supplies industrial flow meters, pressure transmitters with 4-20 mA HART output, and process instruments. We do not claim to be a licensed Invacare distributor. If your neonatal ward needs Invacare branded replacements, contact an authorized medical gas equipment dealer in your region. If you need low-flow gas meters for an OEM skid, a test bench, a cali
How to Specify a Pediatric Low-Flow Gas Regulator for Tender or Procurement
When you write a tender for neonatal care equipment, include the following details on the technical datasheet. Gas type, inlet pressure, outlet flow range, minimum scale division, connection standard, materials, and cleaning requirements. For medical oxygen systems, ask for oxygen cleaned parts and local medical device registration. For air and oxygen mixers, state the accuracy class you need. In practice, a flow range of 0 to 1 L/min with 0.125 LPM lines is enough for most neonatal ward low-flow meters.
Send your gas type, inlet pressure in psi or bar, outlet flow range in L/min, and connection standard to us. Silver Automation Instruments contact details are as follows.

FAQ for Neonatal Gas Flow Meter Buyers
Question: What is the standard flow range for an Invacare pediatric flow meter?
Answer: The most common neonatal range is 0 to 1 L/min with fine graduations. Some units cover 0 to 3.5 L/min or 0 to 5 L/min for blended air and oxygen. Choose the lowest range that supports the clinical protocol because fine control suffers on a wide range tube.
Question: Can I connect a pediatric flow meter to a standard oxygen cylinder regulator?
Answer: Yes, but only with the correct cylinder connection. Oxygen cylinders in many countries use a CGA 540 valve. Some small medical cylinders use a yoke or pin index system. Check the cylinder valve and the flow meter inlet before you buy.
Question: What is the inlet pressure for a wall mounted neonatal flow meter?
Answer: Most hospital wall outlets supply 50 psi from a central gas line. The flow meter body and seals should be rated for that service. Do not connect a low pressure flow meter directly to a high pressure cylinder without a regulator.
Question: Does Silver Automation Instruments sell Invacare branded pediatric flow meters?
Answer: No. We supply industrial flow meters and instrumentation for non-clinical gas applications. We can help a hospital biomedical team compare industrial alternatives for test benches and calibration stands. For branded medical parts, we recommend contacting an authorized Invacare dealer in your country.
Question: How do I check if a pediatric flow meter is accurate after installation?
Answer: Use a calibrated reference flow meter and a steady gas source. Check points at 0.1, 0.25, 0.5, 0.75, and 1 L/min. If the reading deviates more than the tolerance published by the manufacturer, clean the tube, check the ball for sticking, and replace damaged seals. Keep written records for audit.
