This document reports the results of testing four different flowmeters for use in the primary exhaust ventilation ducts of Double Shell Tanks on the hydrogen watch list that do not already have this capability. This currently includes tanks 241-AW-101,241-AN- 103, 241-AN-104, 241-AN-105 and 241-SY-103. The anticipated airflow velocity in these tanks range from 0.25 m/s(50 ft/min) to 1/78 m/s (350 ft/min). Past experiences at Hanford have forced the evaluation and selection of instruments to be used at the low flow and relatively high humidity conditions found in these tanks. Based on the results of this test, a flow meter has been chosen for installation in the primary exhaust ventilation ducts of the above mentioned waste tanks
