Research methodology Mass Import - autoclassified (may be erroneous) ORIFICES are potentially accurate furrow flow devices. Flow measurement accuracy decreases with head loss. Orifice head loss will increase upstream infiltration. Thus, the head loss range must be constrained to maintain measurement accuracy. Design equations are developed for 3-hole orifice plates which give a 23:1 flow range with a 5:1 head loss range. A portable differential point gauge can measure submerged flow head loss to the nearest millimeter. 1986 Article NonPeerReviewed application/pdf en https://eprints.nwisrl.ars.usda.gov/id/eprint/453/1/571.pdf Trout, Thomas J.
