VOLUME FLOW MEASURING ELEMENT - DALL TUBE
Definition
A <VOLUME FLOW MEASURING ELEMENT - DALL TUBE> is a <VOLUME FLOW MEASURING ELEMENT - DIFFERENTIAL PRESSURE> that is a shortened version of a Venturi meter, with a lower pressure drop than an orifice plate. As with these flow meters the flow rate in a Dall tube is determined by measuring the pressure drop caused by restriction in the conduit
