GAS FLOWMETER

摘要

A therapeutic gas flowmeter comprises a body connectable to a therapeutic gas source, a gas flow tube connected to the body, a flow indicator element housed within the gas flow tube, and an electrostatic charge conductor, which extends along the gas flow tube. Said electrostatic charge conductor is in contact with the gas flow tube along said extent. The electrostatic charge conductor is connectable to electrical earth and arranged to disperse electrostatic charge accumulated on the gas flow tube and/or flow indicator element.
