2.7 Free Flow Simulation Testing Methodology
This test is to determine flow rate of Inverter Pump Setting to support the
assembly factors of ram pump at the site. From this testing, correlation between
Inverter Pump Setting and flow rate was produced as references to be used
for application. The result was recorded only after the flow rate is stable. Based
on standard operating procedure of current meter in-situ measurement and its
tolerant factors, the test period had been selected for 300 second (5 minutes) of
each testing.
3 RESULT AND DISCUSSION
A total of 17 test had successfully had been carried out as shown in Table
2. Some of the constraints during the experiments are: (i) modification of precommissioning
test due to unstable pressure at the receiver tank; and (ii)
rectification of inverter pump due to damage to the rubber bush coupling. A
total of six (6) test scenarios was carried out during the testing period.

The Pre-Commissioning Testing and Pre-Dam Simulation Testing were to make
sure the system operate smoothly, and no data were recorded for the test. Data
were recorded for the rest of the testing scenarios for analysis. Table 3 showed
the testing period for different testing scenarios.
