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.
