Description
Technical field
The present invention relates to technical field of petrochemical industry, more particularly to a kind of double flange circle level measuring arrangements.
Background technology
In technical field of petrochemical industry, the different liquid of density, which mixes, can produce lamination, the small liquid of density
Body medium is located at upper strata, and the big liquid medium of density is located at lower floor.If think the medium in mixing liquid and medium point exactly
From, then firstly the need of measuring boundary position of the liquid medium at layering, boundary position refers to two kinds of different liquid medium boundaries
Highly (position).
At present, existing most commonly used method is that circle position is measured using radar interfacial meter, and foundation is radar time domain
Principle of reflection.Specifically, antenna is interspersed in mixing liquid, control radar probe transmitting electromagnetic wave, the electromagnetic wave is in antenna
Middle onwards transmission, when it runs into boundary position, because of the mutation of liquid medium dielectric constant, electromagnetic wave is reflected back, and calculates electricity
Transmission time of the magnetic wave in single liquid medium back and forth, according to the ripple of the transmission time and electromagnetic wave in the liquid medium
Speed, the position where out-of-bounds position can be calculated.However, due to easy adsorbent solid impurity (for example, wax deposition) on antenna, if electromagnetic wave
Solid impurity is run into when transmitting in antennas, then can produce reflex, obtains the transmission time of falseness, and then obtains falseness
Boundary position, the boundary position for causing measurement to obtain are inaccurate.
How to improve and measure the method for accurate boundary position and require study.
The content of the invention
For the drawbacks described above of prior art, a kind of boundary's level measuring arrangement provided by the invention, measurable two media is close
Degree difference is less than 0.11 boundary position, and method is simple, measurement is accurate reliable, and in-site installation is easier to.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of boundary's level measuring arrangement is provided with weight in cylinder below magnetic float, the weight is provided with magnetic material, described
The transducer controller connection that weight is connected with container top flange, the transducer controller control weight interval move down, when
Magnetic float and reading device move down therewith, and when magnetic float stops, reading device stops, and reading device coding no longer changes,
The thing position coding display that reading device is read, the transducer controller control weight move up, and weight promotes magnetic float and reading
Take device to move up, return and stop.
Wherein, the magnetic float also includes：Balancing weight, the balancing weight, for controlling the density of the float.
Wherein, connection magnetic float top surface and the floating hole of magnetic float bottom surface are evenly arranged with the magnetic float；The floating hole,
For reducing fluctuation of the magnetic float in the mixing liquid to be measured.
Wherein, it is provided with stopper between the magnetic float and weight.
Wherein, in addition to：Temperature measurement module, the temperature measurement module are fixedly installed in cylinder, the temperature measurement module, for detecting
The temperature of the mixing liquid to be measured；And then temperature-compensating is carried out to mixing liquid to be measured.
Beneficial effects of the present invention：A kind of boundary's level measuring arrangement provided by the invention, measurable two media density contrast are small
In 0.11 boundary position, method is simple, measurement is accurate reliable, and in-site installation is easier to.
In order to be further understood that the feature of the present invention and technology contents, refer to below in connection with the detailed of the present invention
Explanation.

The thing position coding display that reading device is read, the transducer controller control weight move up, and weight promotes magnetic float and reading
Take device to move up, return and stop.
Further, the magnetic float also includes：Balancing weight, the balancing weight, for controlling the density of the float.
Further, connection magnetic float top surface and the floating hole of magnetic float bottom surface are evenly arranged with the magnetic float；It is described floating
Hole, for reducing fluctuation of the magnetic float in the mixing liquid to be measured.
Further, it is provided with stopper between the magnetic float and weight.
Further, in addition to：Temperature measurement module, the temperature measurement module are fixedly installed in cylinder, the temperature measurement module, for examining
Survey the temperature of the mixing liquid to be measured；And then temperature-compensating is carried out to mixing liquid to be measured.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention described should be defined by scope of the claims.
