OVERVIEW

Precision Flow Measurement for Shielding Gases

The PG20-050CF Replacement Flow Gauge is an essential component for maintaining the accuracy and efficiency of your welding gas delivery system. Designed specifically for flowgauge regulators used in MIG and TIG welding processes, this gauge is calibrated to measure flow rates from 0 to 50 Cubic Feet per Hour (CFH). Unlike standard pressure gauges that measure PSI, the scale on this unit is tailored to interpret the pressure drop across a specific orifice as a flow rate, providing welders with the critical data needed to maintain proper shielding gas coverage.

Constructed with a durable 2-inch diameter case, this gauge offers excellent readability in various shop lighting conditions. The connection is a standard 1/4-inch NPT male thread located at the bottom of the case (bottom mount), ensuring compatibility with a wide range of industrial regulators and flowmeters. The internal mechanism is built to withstand the rigors of daily industrial use, providing consistent repeatability and reliability.

This gauge is suitable for use with inert gases commonly employed in welding, such as Argon, Helium, and Carbon Dioxide (CO2), as well as mixed gases. It serves as a direct replacement for damaged or illegible gauges on existing equipment, allowing maintenance personnel to restore functionality quickly and cost-effectively. Proper monitoring of gas flow is vital for preventing weld defects like porosity and oxidation; this gauge ensures that operators can verify flow settings at a glance.

FAQ

This gauge has a 1/4-inch NPT male thread.

This is a flow gauge. While it operates on pressure principles, the dial is calibrated in Cubic Feet per Hour (CFH) to indicate gas flow rate through a regulator orifice.

No, this gauge is typically designed for inert shielding gases like Argon, CO2, or Helium. Oxygen gauges usually read in PSI and require specific cleaning for oxygen service.

It likely will, provided your regulator uses a bottom-mount gauge with 1/4" NPT threads and is designed for a 0-50 CFH range.

Ensure the system is depressurized. Remove the old gauge with a wrench. Apply appropriate thread sealant to the new gauge threads (ensure no sealant enters the opening) and tighten it into the port.

Bottom mount means the threaded connection sticks out of the bottom of the circle (6 o'clock position). Back mount means it sticks out of the center of the back. This unit is a bottom mount.

No, this measures the output flow. You would need a high-pressure gauge (usually 0-4000 PSI) to measure the remaining tank contents.
