Abstract
The utility model discloses a non-contact liquid level measuring apparatus of an oil field buffer tank, which comprises at least one micro-deformation sensor, a temperature detector and a controller. The micro-deformation sensor is mounted at the bottom of the buffer tank, the temperature detector is mounted on the buffer tank, the temperature detector and the micro-deformation sensor are connected with the controller via conducting wires, and a storage chip is arranged inside the controller. The non-contact liquid level measuring apparatus has the advantages that the apparatus can overcome the shortcomings in the prior art, obtains the height of liquid level inside the tank by measuring micro-deformation of a steel plate at the bottom of the buffer tank, is not affected by viscosity of crude oil, froth on the surface and the like since the whole apparatus doses not need to deeply enter the tank for measuring, is accurate in measuring results, does not need to change a tank body structure as the whole measuring apparatus is completely mounted outside a tank body, guarantees explosive-proof grade and safety grade of the tank body, reduces measuring errors and improves accuracy of the measuring results by arranging a plurality of the micro-deformation sensors, is capable of realizing storage and remote transmission of signals, is convenient in control, reasonable in structure and convenient in installation and the like.
Description
Technical field
The utility model relates to the oil exploitation industrial circle, specifically is oil field surge tank non-contact liquid level measuring instrument.
Background technology
At present, in the surge tank level gauging of oil field, the main measurement mechanism that adopts has roof-mounted magnetic float liquidlevel meter, radio frequency admittance meter, radar level gauge, side-mounted magnetic floating ball lever meter, quartz glass tube liquid level gauge, and throw-in type, end dress formula liquid level gauge.In actual use, more than various measurement mechanisms have a lot of problems, for example: because surge tank liquid level surface in oil field can produce foam, after producing foam, the reflection-type liquid level gauge is measured will produce error, and radar level gauge, ultrasonic level gage also can't accurately be measured; For viscous crude, super viscous crude surge tank, every liquid level gauge that utilizes buoyancy to measure no matter be floating drum or ball float, all can produce adhesion, bite phenomenon, causes the liquid level gauge can't operate as normal; Liquid level gauge for the side dress should also be noted that antifreeze problem in the winter time.Simultaneously, when various liquid level emasuring device is installed on surge tank, often need to change the surge tank structure, cause the explosive-proof grade of surge tank and pressure rating to descend, cause unsafe factor.Therefore, design a kind of factor affecting such as viscosity of crude, surfactant foam that are not subjected to, and need not to change the liquid level gauge of surge tank structure when installing, become the hot research direction of this area.
Summary of the invention
The purpose of this utility model is to provide a kind of oil field surge tank non-contact liquid level measuring instrument, by little deformation that little changing sensor is measured surge tank bottom steel plate, draws the height of jar interior liquid level, need not to insert in the surge tank and use, be not subjected to the influence of pot liquid, measure accurately the safe class height.
The utility model for achieving the above object, be achieved through the following technical solutions: oil field surge tank non-contact liquid level measuring instrument, be included in the surge tank bottom at least one little changing sensor is installed, Temperature Detector is installed on the surge tank, Temperature Detector is connected with controller by lead with little changing sensor, and storage chip is set in the controller.
Leading portion in the surge tank bottom is installed first little changing sensor, second little changing sensor is installed in stage casing in the surge tank bottom, back segment in the surge tank bottom is installed the 3rd little changing sensor, and first little changing sensor, second little changing sensor and the 3rd little changing sensor are connected with controller by lead respectively.
On the described controller wireless signal transmitter is set.
The beneficial effects of the utility model are: can solve the deficiency that exists in the known technology; By measuring little deformation of surge tank bottom steel plate, draw the height of jar interior liquid level, whole device need not to measure in deep jar, not influenced by viscosity of crude, surfactant foam etc., and measurement result is accurate; Entire measuring device all is installed in the tank body outside, need not to change tank structure, guarantees the explosive-proof grade and the safe class of tank body.The further advantage of the utility model is: a plurality of little changing sensors are set, reduce measuring error, improve the accuracy of measurement result; Can realize the storage and the remote transmission of signal, be convenient to control; Rational in infrastructure, easy for installation etc.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark shown in the accompanying drawing: 1, first little changing sensor; 2, controller; 3, wireless signal transmitter; 4, surge tank; 5, second little changing sensor; 6, the 3rd little changing sensor; 7, Temperature Detector.
Embodiment
The principle that the utility model adopted is: because surge tank 4 is the jars that crouch, increase along with inner liquid measure, the bottom steel plate of surge tank 4 can produce little deformation, utilize highly sensitive little changing sensor 1, the trace that can detect bottom steel plate molecular level changes, detection of dynamic is carried out in deformation to the bottom steel plate bending, then in conjunction with the correction that tank wall temperature is changed, has just constituted the complete interior liquid level measuring system of jar of a cover.
In conjunction with the accompanying drawings 1, concrete structure of the present utility model is described further:
Oil field described in the utility model surge tank non-contact liquid level measuring instrument, agent structure is included in surge tank 4 bottoms at least one little changing sensor is installed, Temperature Detector 7 is installed on surge tank 4, Temperature Detector 7 is connected with controller 2 by lead with little changing sensor, in the controller 2 storage chip is set.The trace that little changing sensor can detect surge tank 4 bottom steel plate molecular level changes, and deformation is detected data transfer in controller 2.Temperature Detector 7 can detect the temperature value of surge tank 4, and with the temperature detection data transfer in controller 2, use as modified value.The 2 pairs of deformation of controller detect number and handle, and carry out data correction in conjunction with the temperature detection data, the liquid level in finally drawing jar, and the liquid level result imported in the storage chip preserve.
The further embodiment of the utility model is: in order to improve the degree of accuracy of little distortion measurement, preferably a plurality of little changing sensors are set in surge tank 4 bottoms, three little changing sensors of operated by rotary motion, promptly first little changing sensor 1 is installed at the leading portion of surge tank 4 bottoms, second little changing sensor 5 is installed in the stage casing of surge tank 4 bottoms, at the back segment of surge tank 4 bottoms the 3rd little changing sensor 6, the first little changing sensor 1, second little changing sensors 5 being installed is connected with controller 2 by lead respectively with the 3rd little changing sensor 6.By three positions before, during and after surge tank 4 bottoms are measured respectively, can access more fully measured value, improve level gauging result's accuracy.
In above-mentioned each embodiment,, preferably on described controller 2, wireless signal transmitter 3 is set for the ease of realizing the long-range output of signal.Wireless signal transmitter 3 can be delivered directly to remote control room with the level gauging result, and is even make things convenient for the liquid level information in staff's grasp surge tank 4, very easy to use.
