ABSTRACT:
A wide range laminar flow element for use in differential pressure and thermal mass flowmeters is disclosed. The flow element comprises multiple rectangular channels in a single rectangular plate. The flow element contains tabs which can be selectively removed to alter the effective diameter of the flow channel. Alternatively, the laminar flow elements can be stacked to provide a larger effective diameter of the flow channel.
