Flow Test of the H2 Purifier

Flow Test of the H2 Purifier
Bill Lozowski, 4/11/02
The purpose of this test was to check the flow rate of the palladium H2
purifier for NPDGamma to ensure that the rated flow can be achieved.
Zero-grade UHP hydrogen is introduced to the purifier at 200 psi, with the
purifier output hooked to a graduated cylinder filled with water.
Results of 4 measurements of the time to displace 1000 ml of water: 8.31
sec, 8.15 sec, 8.07 sec, 8.45 sec. Inferred flow rate is 7.3 liters/min.
Estimated error is 5% from reading the graduated cylinder.
