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. Setup: 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.
