Abstract
A gas volume flow gauge is provided with apparatus to ionize the gas being discharged. The gauge has an adjusting valve and a float in a vertical gas passage to indicate the flow rate; an ionizing point is provided in the gas outlet passage, and is capacitively coupled to a conductor connected to an alternating current source. A grounded conductive ring surrounds the ionizing point.
Claims8
In combination,
- (a) a gas volume flow gauge comprising:
- (i) a body,
- (ii) gas passage means in said body comprising a bore providing a substantially vertical passage,
- (iii) means for indicating the gas volume flow rate including a float in said substantially vertical passage,
- (iv) means for varying the gas volume flow rate, and
- (b) means for ionizing gas passing from said gauge comprising ionizing point means in said gas passage means, means for supplying alternating current to said ionizing point means comprising a conductor adapted to be connected to a source of alternating current, a second bore in said body, said conductor being in said second bore, means carried by said body for coupling said point means to said conductor, conductive means carried by said body in adjacent spaced relationship to said ionizing point means, and means for connecting said conductive means to ground.
