  • Patent number: 4048844
    Abstract: Electric system for a meter for measurements of density of the mixtures conveyed in pipelines. The system has a capacity sensor installed in a pipeline and being connected, via a capacitance transducer, with a system compensating temperature induced variations in capacity. The input of the said system is connected with a temperature sensor installed in the pipeline, while the output of the said system is connected with an indicator-recording system. Instead of being connected with the input of the system, the temperature sensor can be connected with the capacitance transducer which is then connected directly with the indicator-recording system. In the case of the mixture temperature's being constant or varying within a narrow range, the electric system of the meter comprises a capacity sensor connected, via the capacitance transducer directly with the indicator-recording system.
