Mechanical Flowmeter 32 GPM

The Dayton 12F736 is a mechanical flowmeter designed for measuring diesel and oil flow in industrial or automotive plumbing systems. It handles flow rates between 5 and 32 GPM with a stated accuracy of +/-1 percent. The aluminum housing and Buna-N seals suit media temperatures from -10 to 140 degrees F. Connections use 3/4 inch FNPT threads.

Replacing Sight Glasses Or Estimates

This meter replaces visual estimation or simple sight-glass checks where a numeric reading is needed for dispensing or transfer logging. The jump is worth it when operators require a repeatable mechanical display without external power and the fluid viscosity stays below 9,400 SUS. It fits existing 3/4 inch FNPT piping without adapters.

Suits Diesel And Oil Lines Up To 145 PSI

Technicians monitoring fuel or lubricant transfer on mobile or stationary equipment will find the mechanical display reliable in the field. Buyers needing electronic output, data logging, or compatibility with water-based fluids should look at other technologies. The unit is restricted by California Proposition 65 for listed chemicals.

Questions about this item

What pipe size and thread type does the 3/4 in FNPT connection require?

The meter mates with 3/4 inch female NPT threads on both inlet and outlet.

Which orientation and sealing method should be used during installation?

Install the meter in a horizontal run with flow in the arrow direction and seal the FNPT threads with PTFE tape or pipe dope.

When should the Buna-N seals be inspected or replaced?

Check the Buna-N seals annually or whenever the meter sees temperatures near the 140 °F maximum or pressures approaching 145 psi.
