Abstract: A digital position transmitter is disclosed which uses a fixed array of physicoelectric proximity switches to locate a physical exciter and transmit the position of the exciter as a hexadecimal coded number or as a string of pulses. The position transmitter uses solid state components, has no moving parts and requires less power than any one proximity operated alone. The transmitter attains moderate resolution while displaying excellent accuracy and precision. The transmitter is completely non-intrusive; there is no contact between the physical exciter and the switch array, making the transmitter particularly suited for determining the position of objects that must be completely isolated because of pressure, temperature, of chemical hazards. Further circuits are described for converting the inherently digital output signal to industrial standard 4-20 mA or voltage signals.

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.
