VOLUME FLOW MEASURING ELEMENT - DALL TUBE
A class with identifier
http://staging4.data.posccaesar.org/iso/15926-4/rdl/RDS7023655
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 |
ISO number | 4306 |
Note | A dall tube is very much like a venturi tube, but has a higher ratio of pressure developed to the pressure lost and is more compact. |
RDS number | RDS7023655 |
