Description
Technical field
The utility model belongs to the level gauging field of oil well head pipeline, store oil equipment, and in particular to a kind of conductivity
The measuring instrument of method measurement oil-water interfaces.
Background technique
The product of the current liquid level of measurement now, is largely ordinary level transmitter, and principle is exactly according to insertion liquid level
Sensor depth, come what is measured.By the sensor inside insertion liquid, controller is transferred signals to, amplifies and changes
It calculates, obtains the depth etc. of liquid level.It is low that this method measures the result precision conversed, and accuracy is also not high enough.This Shen
It is all electric conductor original that the method measurement intracorporal oil-water interface tool of tank that please use conductivity, which is according to petroleum and water (except distilled water),
Reason, has the physical concept for describing the object conductive capability size, i.e. conductivity as electric conductor.Utilize petroleum and water
Different conductivity principles, by oil and water and other mixing liquid separating and measurings, to be isolated identification.
Utility model content
The purpose of this utility model is to solve the above problems, provide it is a kind of facilitate user order goods, maintenance and observation operation
The measuring instrument of electrical conductivity method measurement oil-water interfaces.
To achieve the above object, the utility model provides the following technical solutions:
A kind of measuring instrument of electrical conductivity method measurement oil-water interfaces, is placed in container, water and stone is contained in the container
Oil, measuring instrument top are equipped with controller, and the controller is equipped with interior electrode by connector connecting flange, the flange lower section,
The external rings of the interior electrode set external electrode；The interior electrode and external electrode are all connected with controller, and by the electricity of its measuring medium
Conductance is transmitted to controller；The controller is equipped with display screen, for the structure for integrating control display.
Further, the container is liquid tank, cabinet or collecting tank.
The utility model has the beneficial effects that:
The utility model is by oil-water interface tool, by the liquid in the same container or in the storage pond of plurality of liquid mixing
Body is isolated identification using their different conductivity principles, is transmitted to control display instrument control respectively by electrode
It is shown on device processed.Controller has been mounted on cassette holder, and a people can complete wiring and weldering when the cap is opened in this way
Connect work.User is facilitated to order goods, maintenance and observation operate.
Detailed description of the invention
In order to illustrate more clearly of the utility model embodiment technical solution, will make below to required in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model in order to more clearly
Illustrate the utility model embodiment or technical solution in the prior art, for those of ordinary skill in the art, is not paying
Out under the premise of creative work, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of measuring instrument of electrical conductivity method measurement oil-water interfaces as shown in Figure 1, is placed in container 1, the container 1
Interior that controller 4 is equipped at the top of measuring instrument containing water 2 and petroleum 3, the controller 4 passes through 5 connecting flange 6 of connector, the method
6 lower section of orchid is equipped with interior electrode 7, and the external rings of the interior electrode 7 set external electrode 8；The interior electrode 7 and external electrode 8 are all connected with control
Device 4 processed, and the conductivity of its measuring medium is transmitted to controller 4；The controller 4 is equipped with display screen 41, for collection control
Show the structure being integrated.
Further, the container 1 is liquid tank, cabinet or collecting tank.
The oil-water interface tool of the method measurement container 1 of the utility model conductivity, is according to 2 (distilled water of petroleum 3 and water
Except) it is all electric conductor principle, there is the physical concept for describing the object conductive capability size as electric conductor, i.e., it is conductive
Rate.Conductivity is the concept of the ability of solution conduction electric current numerically.Unit: Siemens is per second/rice (s/m).It influences
Conductivity because being known as, temperature, doping level, each face opposite sex etc..
Petroleum 3 and water 2 are two different liquid, and conductivity also has very big difference.The conductivity of petroleum 3 be (1~
2)×10-4S/m, and the conductivity of water 2 (tap water) is 0.5~5.0 × 10-2S/m, it can be seen that petroleum 3 and water 2
Conductivity differs hundred times, therefore the conductivity for passing through measuring medium, it may be convenient to which measuring which section in pot liquid is water
2, which section is petroleum 3, and can obtain the interface of petroleum 3 and water 2.
The course of work: the internal and external electrode part of oil-water interface tool is inserted into tank body or other fluid boxes or pond.When
After internal and external electrode adds working power appropriate, different liquids will generate different conductivity on the electrode.It is transferred to control
The comparison of device 4 just can know that substance is that a part in container 1 be respectively.This principle is exactly the difference electricity using liquid
Conductance, the result to convert.
The utility model is by oil-water interface tool, by the liquid in the same container 1 or in the storage pond of plurality of liquid mixing
Body is isolated identification using their different conductivity principles, is transmitted to control display instrument control respectively by electrode
It is shown on device 4 processed.Controller 4 has been mounted on cassette holder, so when the cap is opened a people can complete wiring and
Welding.User is facilitated to order goods, maintenance and observation operate.
The content not being described in detail in the utility model is the prior art.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
