Abstract

Device for measuring pressure differences or mass portions in a fluid flow--gas or liquid--and/or for implementing processes for mixing fluids, whereby when in use the fluid flows into the device, then passes a part therein where the fluid flow is laminar and the flow measurement is made, and finally flows out of the device, whereby the device has a turbulence filter which is integrated therein, with a settling chamber behind it. The fluid then first flows through that filter, so that a laminar flow leads to the flow measuring element.
