title: Orifice Plates for Furrow Flow Measurement: Part II - Design and Field Use
ispublished: pub
subjects: research
subjects: autoclass
divisions: d_unclass
abstract: 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.
