Sensor in use for measuring humidity ratio in product oil

Abstract

A transducer used for measuring water ratio of oil finished product is prepared as setting standard oil sample measurement cylinder and measurement cylinder of oil sample to be measured on erection support and applying capacity oil sample measurement cylinder as two said measurement cylinders, forming capacity oil sample measurement cylinder by two cylindrical semicircular electrodes in insulation barrel, arranging insulation semicircular bush and metal semicircular bush both being coordinated to each other on two ends of two said electrodes and setting end cover on each end of insulation barrel.

Description

technical field [0001] The invention relates to a measuring sensor, in particular to a sensor for measuring the water content of refined oil. Background technique [0002] In the era of planned economy and the early stage of reform and opening up, oil exploration, collection, refining, storage, transportation, and sales of refined oil were all managed and monopolized by relevant government departments. The quality of refined oil is only controlled by oil refining enterprises from the source according to national standards; this is a small proportion of private enterprises and private vehicles, and the national gas stations are all state-owned enterprises of the same system, and vehicles do not accept cash for refueling , Only oil tickets are accepted; the quality of refined oil, especially the water content, is basically above the qualified standard, so people also feel that it is unnecessary to carry out the quality and actual water content of the refined oil in the storage...

Problems solved by technology

[0011] The above-mentioned known GB260-77 (confirmed in 1988) "The determination of moisture content in petroleum products" stipulates time-consuming distillation and determination of moisture content, which cannot be directly sampled and measured at present; Product oil-water degree measuring instrument, the measurement signal-to-noise ratio is low, and the error caused by the fluctuation of the dielectric constant in a certain range due to the type, label, production area and temperature change of the product oil is difficult to determine and deal with.
