Embodiment
Principle of the present invention is as follows: the quality of material unit volume, i.e. density p=M/V, wherein mass M is converted to quality by the weight of this material of precision measurement, and for the volume V of material, usually the volume of an object will be measured, in this way square and the wide * of long * high, get its length when being generally 100mm, if when precision is 0.1mm, its volume is 100.1*100.1*100.1=1003003 cubic millimeter, certainly also may be 1000000 cubic millimeters, its measure relative accuracy be the two difference divided by 1000000 be 0.003 that is 0.3% precision, obvious volumetric errors is too large, if survey to as if random time, its error can be larger, thus the volume accuracy that draws of this kind of measuring method is not high, therefore the present invention proposes the theory substituting measurement volumes by measurement weight.Usually, measure weight as 300g, it is easily that precision reaches 1mg, and as 300.001g, its relative accuracy is 0.00033%; And when measuring regular shape or irregular density of solid, weigh its volume size, according to Archimedes' principle, put into distilled water, see its weight arranging aqueous solution/now water temperature density, get final product the volume that high precision knows this object, its precision magnitude is similar to check weighing magnitude.
Based on above-mentioned theory, the present invention proposes a kind of wireless data sending online Water Content in Oil quantitative determination instrument, for making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one, the present embodiment proposes a kind of underslung type Water Content in Oil quantitative determination instrument, is mainly used in the measurement of field condition petroleum crude oil or oil mixing with water oil, as Figure 1-3, comprise casing 1 and position hardware circuit in the inner, described casing 1 is square, and upper surface has display screen 2, button 3, button can set power supply, verification and computing button, certain casing 1 also can be arranged to cylindrical as shown in Figure 5, and cylindrical upper end portion has contracting neck structure 11, is convenient to mobile, lifting; Described hardware circuit is with reference to figure 4, the wireless data transmission module comprising power supply, processing module, temperature sensor, strain transducer and be connected with two sensors, described strain transducer measure suspended matter on suspension hook pulling force or by sending through wireless data transmission module after processing module process, or first sending again by exporting Water Content in Oil amount after processing module process through wireless data transmission module, described processing module is in order to go out Water Content in Oil amount by the pulling force of reception by formulae discovery and to export.
The strain beam of described strain transducer 5 is provided with the suspension hook 4 stretching out casing, suspension hook 4 can hangs probe 6 or tested solid, wherein probe 6 or tested solid are hung on suspension hook 4 by vertical line.Probe 6 can be made into standard probe, and by weight, volume, shape, size, material be divided into different models, and described probe shape can be made into elliposoidal or taper or cylindricality, and material can adopt stainless steel or crystal glass or teflon to make.Described vertical line adopts lightweight flexible cord to make, as plastics, nylon wire or wire etc.In order to measure accurately, also comprise one and being arranged on the temperature sensor be connected with described wireless data transmission module in casing, being immersed in solution to be measured when the gauge head of this temperature sensor uses.
During measurement, choose the probe of setting, the choosing according to the water cut of tested oil and field condition and determine of probe, then probe suspension is submerged in wet oil to be measured on suspension hook, and the gauge head of temperature sensor is immersed in testing liquid, now, strain transducer will record pulling force or first send again by exporting Water Content in Oil amount after processing module process through wireless data transmission module, client process module by formula S=| (PX-P0) | k1*k2 calculates S value, wherein, S is the water cut of oil, the weight of the wet oil of PX shared by described probe size, the weight of the pure oil of P0 shared by described probe size, k1 is the water cut modified value of oil, k2 is unit conversion ratio constant.Like this, remote terminal computing machine can calculate Water Content in Oil amount " true value " all the time, also can gather or draw corresponding change curve.
Certain processing module also can be built in casing, like this can data processing is complete after sent by wireless data transmission module again, its process no longer describes in detail.
When tested liquid flow, for ensureing measuring accuracy, also comprise a cylindrical sheath, on sheath side, symmetry has two row through holes, during concrete use, the line between two row through holes perpendicular to the direction of liquid flow, will so both ensure that the true samples of liquid turn avoid interference.
Why precision is high in the present invention, measuring process is converted to final Water Content in Oil amount by measured weight on the one hand, on the other hand, the calibration process of instrument is also realized by measured weight, be the ratio of the difference of the density of wet oil PetroChina Company Limited. density and wet oil PetroChina Company Limited. density and pure oil as the K1 in formula, wherein wet oil PetroChina Company Limited. density in calibration process by relevant Instrument measuring, but processing module is mainly by the pulling force of reception, and by formula K={W/, (A-B}-C}*D calculates density and exports, wherein, K is wet oil density; W is the weight of the wet oil that probe arranges; A is probe volume at room temperature; B is bulk temperature modified value; C is density revision steady state value; D is unit conversion value proportionality constant.
In order to convert accurately, the present invention proposes to utilize oneself to know (as 0-100 DEG C) watertight angle value of water purification different temperatures, in order to demarcate other material densities, greatly can improve the precision of measured value.The density of the water of 0-100 DEG C is as shown in following table one:
The density of the water of table one: 0-100 DEG C
The above; it is only preferred embodiment of the present invention; it is not restriction the present invention being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field the liquid of similar requirement, the control of gas; but everyly do not depart from technical solution of the present invention content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present invention is done above embodiment, still belong to the protection domain of technical solution of the present invention.
