Dayton 32ZN69 Digital Flowmeter

The Dayton 32ZN69 is a turbine-style digital flowmeter built for measuring AdBlue, DEF, water and windshield fluids. It fits a 1-inch FNPT connection and covers a flow range of 1.3 to 32 gallons per minute. Technicians and fleet operators use it to track fluid dispense volumes in workshop and mobile service settings. The LCD readout shows totals in gallons, litres, pints or quarts.

Practical limits of the interface

The meter operates between 14 and 122 degrees Fahrenheit and withstands up to 145 psi of line pressure. Accuracy is rated at plus or minus one percent across the stated range. Maximum fluid viscosity is 40 SUS, so thicker oils or glycol-heavy mixes beyond that limit will not read correctly. Wetted parts are nylon and stainless steel for chemical compatibility with the approved fluids.

Deciding specification — flow range

The 1.3 to 32 GPM span decides whether this unit suits the job. Systems that regularly run below 1.3 GPM or above 32 GPM need a different meter. Buyers who need higher viscosity capability or a smaller connection size should look elsewhere.

Questions about this item

Which flow range version suits my pump, 1.3 to 32 gpm or 78 to 1920 gph?

Both figures describe the same meter; 1.3 to 32 gallons per minute equals 78 to 1920 gallons per hour, so choose the unit that matches your pump spec.

What does the 5.35 cps rating mean when the meter is installed?

The turbine generates 5.35 pulses per second at one gallon per minute, giving the electronics a direct speed signal for the LCD readout.

How does the FNPT connection and 145 psi limit affect what I can plumb?

The 1 inch female NPT thread seals with standard pipe fittings, and the housing is rated to 145 psi maximum working pressure.
