VOLUME FLOW MEASURING ELEMENT - MULTIPLE JET
Definition
A <VOLUME FLOW MEASURING ELEMENT - MULTIPLE JET> is a <VOLUME FLOW MEASURING ELEMENT - VELOCITY> that is a velocity type meter that has an impeller that rotates horizontally on a vertical shaft. The impeller element is in a housing in which multiple inlet ports direct the fluid flow at the impeller causing it to rotate in a specific direction in proportion to the flow velocity. This meter works mechanically much like a single jet meter except that the ports direct the flow at the impeller equally from several points around the circumference of the element, not just one point; this minimizes uneven wear on the impeller and its shaft
