Abstract
A density meter for continuous fluid flow including a plurality of hollow flexures, a relatively fixed support for one end for each of the flexures, and a closed container supported by, and interiorly communicating with, the opposite ends of the flexures. One or more of the flexures conduct a flowing fluid into the container, and the other of the flexures conduct a flowing fluid out of the container. Changes in fluid density produce flexure deflection, the container when filled with fluid being supported in every position by the deflecting flexures. A transducer is provided to convert such deflection into an electrical displacement signal, and a first processor is connected to the transducer to convert such electrical displacement signal to an electrical weight signal. An additional element is provided to produce an electrical volume signal, and a second processor is connected to the first processor and to the additional element to combine the weight signal with the volume signal to produce a density signal, which may be temperature and pressure compensated.
