Quick verdict
Before you buy, decide what will flow through the meter: the two candidates here serve opposite sides of pressure flow process measurement. The Mig Tig Flow Meter Regulator Argon CO2 Gas Welder Welding Weld Regulator Gauge, at $27.59, is built for welding gas. The Digital Fuel Flow Meter 1" Electronic Flow Gauge Turbine Diesel Flow Meter USA, at $34.99, is an electronic flow meter with an LCD display for liquid fuels. Choose the Mig Tig for a welding gas line, and choose the Digital Fuel Flow Meter for liquid fuel transfer.

Where each product wins
The Mig Tig wins when your flow is gas rather than liquid. It pairs regulation with a gauge-style readout in one unit, and it carries the lower listed price of the pair. That makes it the straightforward pick for a MIG/TIG welding station.
The Digital Fuel Flow Meter wins when your flow is a liquid. The meter is suited to transfer work with fuel, and it can switch between QTS, PTS, GAL, L, and m³ units. That digital readout makes it the stronger choice when you want a quick volume reading on a fuel line.
Product notes
Mig Tig Flow Meter Regulator
If you are setting up a MIG or TIG welding station, this regulator is aimed directly at argon and CO2 welding gas. It is the lower-priced option in this pairing, and it works as a gas regulator with hose, so you get a gauge-style flow reading on the gas line rather than a separate electronic display. The practical limit is that this is a gas-focused regulator, not a liquid flow meter. It will not give you the turbine-based digital readings you need for fuel transfer work. For a welding gas line, it is the tool that fits the job; for liquids, it is the wrong direction.
Digital Fuel Flow Meter
Choose this meter when you need to measure liquids rather than shielding gas. The 1-inch turbine design and LCD display are set up for diesel, gasoline, kerosene, and water, and the meter can switch between QTS, PTS, GAL, L, and m³ units. That unit flexibility is useful when you are tracking fuel usage and want a clear digital readout. The limitation is that it is not a regulator for shielding gases: those gases are outside its intended fluid list, and the LCD needs protection from water since the display can be damaged by moisture. For liquid flow measurement, this is the better match; for shielding gas, stick with a welding regulator.
Final choice by use case
Choose the Mig Tig Flow Meter Regulator when the flow is gas, and choose the Digital Fuel Flow Meter when the flow is a liquid. The fluid you are measuring matters more than the price gap.
