Abstract
A gas leakage meter (100) for use onsite in a process plant comprises a housing (110) with an inlet (101), an outlet (102) and an inlet nozzle (111) fluidly connected to a unit to be tested (3) through a downstream connector (1040) and to the inlet (101), the housing (110) being filled with a liquid to a level (10). An inclined pipe (120) is arranged such that, in use, test gas released from the inlet nozzle (111) raises through a liquid and the inclined pipe (120) to a gas-collecting chamber (122) at an upper end of the inclined pipe. (120). The gas-collecting chamber (122) has a gas release valve (150; 170) for releasing test gas before a test period. Embodiments where the inclined pipe (120) is mounted on a pivot and alternative gas release valves (150, 170) are also disclosed.
