When metering gases, where is the position of the weep hole?

The weep hole is located at the bottom of a gas metering device. Its primary purpose is to allow any accumulated liquid to escape, preventing it from interfering with the accurate measurement of gas flow. If liquid were to collect in the metering section, it could create inaccuracies in measurements or even cause damage to the device if left unaddressed.

A correct placement at the bottom ensures that any condensation or stray liquids naturally flows out due to gravity, maintaining optimal conditions for gas measurement. Proper positioning of the weep hole is crucial for maintaining the integrity and accuracy of gas metering systems.
