Abstract

The multiphase material level sensor can be used not only for measuring oil-water interface position, but also for accurately measuring material levels of crude oil, sewage and mud-sand. Said sensor has a capacitor transmitter and a connection body, which is technically characterized by that the outer side of said connection body is equipped with an internal insulating cover, and the outer side of said insulating cover is equipped with multisectional tubular metal branch electrodes, between two adjacent branch electrodes an insulating layer is set, outer side of every branch electrode is equipped with an external insulating cover, internal cavity of the connection body is equipped with cable, and the branch electrode is connected with the capacitor transmitter electrically by means of cable.

Description

Technical field [0001] The invention relates to a measuring device, in particular to a multi-phase material level sensor capable of measuring crude oil, sewage and sediment in an oil storage tank in a full range. Background technique [0002] At present, the crude oil recovered from oil wells in oilfields has undergone impurity removal and dehydration processes to become qualified commercial crude oil, which is injected into various storage tanks for export or transportation. Due to the incomplete removal of impurities and dehydration, a thick layer of sludge will be deposited on the bottom of the oil storage tank over time, and there is a section of sewage on it. Crude oil is on the sewage. Since the oil field needs to keep abreast of the output of the oil production plant, it is necessary to measure the oil storage volume frequently. However, the current measurement method is to climb up the oil tank manually, and hang a heavy object from the artificial mouth with a rope ...
