Appendix: Dickey-john Flow Meter Calibrations
Note: The flow sensor constant is stamped on the Dickey-john flow meter. Refer to the
Dickey-john manual for information on the density setting.
Flow meter calibration for Anhydrous Ammonia (NH
3)
Use the following formula for flow meter calibration for Dickey-john reading pounds of
anhydrous ammonia.
Flow sensor constant (pulses/in
3
) x 1728 (in
3
/ft
3
) x 5.11 (lbs. of anhydrous/gal.)
Density (lbs. of anhydrous/ft.

)
Flow meter calibration for nitrogen (N)
Use the following formula for flow meter calibration for Dickey-john reading pounds of
Nitrogen.
Flow sensor constant (pulses/in
3
) x 1728 (in
3
/ft
3
) x 4.22 (lbs. of Nitrogen/gal.)
Density (lbs. of Nitrogen/ft.

PRODUCT NOTES
Raven
Raven flow meter tags represent pulses per 10 gallons. Divide Raven’s
tag number by 10 if this is the case.
Tee Jet
Tee Jet meter calibration numbers are pulses per liter. To conver the
number, multiply the value found on the flow meter by 3.79 to find the
pulses per gallon needed for the InSight display.
Mid-Tech
Mid-Tech flow meters sometimes have a cable with a module. The
calibration number found on this cable is in pulses per gallon/divided
by 16. The InSight display should bypass this module and plug directly
into the flow meter. If that is the case then multiply the calibration
number by 16 before entering it into the InSight display.
