Pengujian Orifice Flow Meter dengan Kapasitas Aliran Rendah
Abstract: Orifice flow meter is
used in many laboratory and industrial application due because of its simple
design and low cost. The present research investigated an orifice flow meter
operated in relatively low flow rate. Orifice plate is a metal plate, 10 mm
width provided with bevel at inlet section. The diameter ratios (β) are 0.3,
0.4, 0.5,0.6, 0.7, and 0.8, respectively. The experiment used water with
flowrate range having Reynolds number between6827,55 and 8004,72. The fluid is
flown through the orifice plate. Pressure taps are used to measure pressure atupstream
and downstream of the orifice plate. The actual capacity is directly measured
at an outlet reservoir;while the theoretical capacity is calculated using
modified Bernoulli equation with diameter ratio (β) within theequation. The
results showed that the irrecoverable pressure drop decreased with the increase
of flow capacity and the diameter ratio. The discharge coefficient of the
orifice flowmeter ranged between 0.3 and 1.3.
