Digital display type oil-water interface detector

Abstract

The invention discloses a digital display type oil-water interface detector which comprises a detector body, a measuring scale, a probe, a microprocessor, an LCD, a magnetic steel body and a rotation angle sensor. The detector body comprises a shell and a rotary disk. The measuring scale is formed by combining a flexible rule tape with scales and a guide wire. The probe is connected with the guide wire arranged in the measuring scale and extending out of the detector body. A flexible rule tape disk is arranged in the detector body. A medium sensor is arranged in the probe. The microprocessor is arranged in the rotary disk. The LCD is arranged on the front end face of the rotary disk. An output end of the microprocessor is connected with the LCD. The other end of the measuring scale in the detector body is connected with the microprocessor through the guide wire. The magnetic steel body is fixedly connected to the center of the shell. The rotation angle sensor is fixedly connected to the center of the flexible rule tape disk, and the rotation angle sensor corresponds to the magnetic steel body in radial position. The rotation angle sensor is connected with the microprocessor through the guide wire. The digital display type oil-water interface detector can obviously reduce influences of manual factors and carry out oil-water interface detection easily and accurately.

Description

technical field [0001] The invention relates to an oil-water interface detector. Background technique [0002] The oil-water interface detection technology is widely used in oil field crude oil extraction in the petroleum industry, oil-water interface detection in oil storage tanks and sewage oil tanks in the shipbuilding industry, and mixed liquid interface detection in the chemical industry. The oil-water interface detector in the prior art includes a detector body, a measuring ruler, and a probe. The detector body includes a housing and a turntable. The detector body is equipped with a measuring ruler that can be coiled through a rotating motion and drives the measuring ruler to protrude from the detector body. Or the retracted tape measure disc has a measuring ruler reading window on the housing; the measuring ruler is composed of a scale tape with a scale and a wire. The probe is connected to the wire in the measuring ruler protruding out of the detector body. There ar...

Problems solved by technology

The oil-water interface detector in the prior art has a simple structure, but the scale of the measuring ruler may be difficult to read or cause a large reading error due to oil pollution when used; the operator may also cause a large reading error due to visual errors; the above Both aspects will lead to large measurement errors; on the other hand, with the oil-water interface detector of this structure, the operator needs to read and record the data continuously, and the labor intensity is relatively large.
