1. Method of Calibration
The meter to be caiib「ated was insta=ed in a standa「d tes川ne of wate「 flow laboratory as
Shown in figu「e l’Schematic of calibration Setup. The iine was flooded and ent「apped air
CIea「ed using ci「cuit air bleeds. Constant Head Tank I Di「ect pumping was the fiow source fo「
the calibration. FIow 「ate was adjusted ’using the downst「eam controi valve. When flow
COndjtions had stab帥sed’the fIow rate was determined by collecting wate「 fo「 a measu「ed
time interva=n the weighing system. The method used was fIying-Sta巾and-finish tec回que
Where the flow was diverted in to the weighing system and diverted back at the end of
test.丁he reference mete「 was used to measu「e flow「ates above 2500 m31h.
The time of co=ection was determined by a high precision timer, Which was trigge「ed by a
Photo switch-time「 biade arrangement attached to the diverfer. DifferentiaI pressu「e was
measured using high p「ecision d冊e「ential p「essu「e t「ansmitter, Whe「e output is ave「aged
using high speed data acquisition system. Water temperatu「e and wate「 p「essu「e we「e aiso
recorded. The actual fIowrate・ theo「etical flowrate, COe冊cjent of discha「ge, and Rey=Olds
numbe「 were then calcuiated. This p「ocedure was 「epeated fo「 the other flow rates aIso,
