Abstract
The invention discloses a direct liquid level boundary indicator, which is mainly formed by sequentially connecting and assembling a sensor casing, a boundary floater, a liquid level floater, a mounting flange and a transmitter casing into a whole. When the direct liquid level boundary indicator is in use, the sensor casing is provided with a sensor through connection, and then the he direct liquid level boundary indicator is put into mixed liquid of oil and water to measure an oil-water boundary.
Description
Affiliated technical field
The present invention relates to the measuring instrument that a kind of oil exploration industry uses, particularly a kind of direct liquid level circle position measuring instrument is suitable for liquid level and position, boundary height in the measuring vessel, obtains its information, to meet the needs of production.
Background technology
At present, traditional liquid level circle position measurement means can change because of pressure, make detecting element compressive deformation or damage, causes the detection bodies volume change and causes measuring error.Because of being subjected to detected density of medium, temperature effect, often produce measuring error again, and, can cause measuring error bigger because of variable density by measuring the method for differential pressure measurement height.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of direct liquid level circle position measuring instrument is provided.This measuring instrument is not only reasonable in design, make simply, and detected density of medium is very little to the influence that spheroid buoyancy produces, and therefore, error information detection is very little.
The technical solution used in the present invention is: sensor outer housing be linked in sequence interface ball float, liquid level ball float, mounting flange, the transmitter shell is assembled into one and constitute.During use, sensor outer housing connection sensor is inserted the present invention in the liquid of oil, water mixing, promptly can be used for measuring oil, water termination.
1, adjusts the weight of interface ball float, make it can sink to water liquid, and can be good at floating between the water liquid, make it can reflect the height at interface really.Sensor is directly measured the position of ball float, by transducing unit, position signalling is transformed into 4～20mADC signal is transferred to monitoring and control system.
2, adjust the weight of liquid level ball float, make its top can the emersion oil level, can reflect the height of oil level really.Sensor is directly measured the position of ball float, by transducing unit, position signalling is transformed into 4～20mADC signal is transferred to detection and control system.
The invention has the beneficial effects as follows, simple in structure, easy to use, be mainly used in oil exploration industry, two ball floats are shared a cover sensor, exportable two groups of data of while, data are accurate, control oil and water separation effectively, improved work efficiency greatly.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Accompanying drawing number is: 1, sensor outer housing, 2, the interface ball float, 3, the liquid level ball float, 4, mounting flange, 5, the transmitter shell, 6, oil, 7, water.
Embodiment
With reference to Fig. 1, sensor outer housing (1) be linked in sequence interface ball float (2), liquid level ball float (3), mounting flange (4), transmitter shell (5) is assembled into one and constitute.During use, sensor outer housing (1) connection sensor is inserted the present invention in the liquid of oil (6), water (7) mixing, promptly can be used for measuring oil (6), water (7) interface.
1, adjusts the weight of interface ball float (2), make it can sink to water (7) liquid, and can be good at floating between water (7) liquid, make it can reflect the height at interface really.Sensor is directly measured the position of interface ball float, by transducing unit, position signalling is transformed into 4～20mADC signal is transferred to monitoring and control system.
2, adjust the weight of liquid level ball float (3), make its top can emersion oil (6) liquid level, can reflect the height of liquid level really.Sensor is directly measured the position of ball float, by transducing unit, position signalling is transformed into 4～20mADC signal is transferred to detection and control system.
