Gas Metering Pumps - are there such things ?
We have an application that requires 2 combustible gases (fuel gas and Oxygen)to be mixed in-line and then filled into a chamber where the mix is ignited. Not only should the volume ratio be accurately controlled but also the degree of mixing.
We currently use pre-charge chambers, which we fill to a set pressure and discharge simultaneously - these work fine but a little on the slow side.
I was thinking that in-line metering devices like Gear Pumps could also work. Anyone know of any?
We have also tried fixed orifices but results were poor.
