Product Information
Full details
The AB Tools Welding Gas Bottle Flowmeter (EA093) is an essential tool for professional welders and hobbyists alike who need precise control over gas flow rates to ensure high-quality weld beads. By providing an accurate visual reading in litres per minute (LPM), it helps prevent gas wastage and porosity issues caused by incorrect flow, though users should note it requires a separate gas regulator to function, as this unit does not control pressure independently.

FAQs
Does this flowmeter control the gas pressure?
No, this unit only measures and adjusts the flow rate in LPM. The gas pressure must be set independently using your gas regulator.
Can I use this with CO2?
Yes, this flowmeter is compatible with all standard welding gases, including CO2 and Argon mixtures.
What is the maximum LPM I can measure?
The gauge scale is calibrated for a range of 0-14 LPM.
Is the inlet connection a standard size?
Yes, it features a standard 3/8 inch BSP inlet, which is compatible with most workshop welding equipment.
Does it matter what angle I mount the unit at?
Yes, the unit must be mounted vertically. If it is tilted, the internal ball will not provide an accurate flow reading.
Troubleshooting
The indicator ball is stuck at the bottom.
Ensure the gas regulator is open and the cylinder has sufficient pressure. If the ball is stuck due to debris, gently tap the side of the housing.
Flow reading is inconsistent or jumping.
Check that the flowmeter is installed perfectly vertically and that there are no kinks in the gas hose leading to the welder.
Leaking at the connection point.
Ensure the 3/8 inch BSP connection is tightened sufficiently and inspect the O-ring or sealing washer for damage.
Pros and Cons
Pros
- Highly accurate gas flow measurement
- Easy to install with standard 3/8 inch BSP fittings
- Clear, intuitive visual ball indicator
- Compatible with a wide variety of welding gases
Cons
- Requires a separate gas regulator to function
- Not intended for high-pressure industrial applications exceeding 14 LPM
- Requires vertical mounting for accurate readings
Setup, Compatibility & Care
Installation is straightforward: ensure your gas cylinder is closed, then attach the 3/8 inch BSP threaded inlet to your existing pressure regulator outlet. Use a suitable wrench to tighten the connection, but avoid over-tightening to protect the threads. Because this flowmeter relies on gravity to position the indicator ball, it must be mounted vertically. To maintain the device, keep the assembly free of dust and debris, as particles entering the tube can interfere with the ball's movement. If the tube becomes dirty, wipe the exterior with a clean, dry cloth; do not use harsh solvents that could cloud the plastic casing.
