@brucemo You can use two bridges going into the mechanical filter to filter the gas. If your gas line is flowing up you put a bridge folowed by another one but the gas valve's input below or to the right of the output. If there is a 1Kg packet flowing in the first bridge it will merge with the 1g of the mechanical filter but leaving 1g on the output but there is another bridge that will pick it up so it will merge and form a 2g packet in the loop of the mechanical filter.
