Description
Technical field
The utility model relates to a kind of liquid level emasuring device, especially a kind of device measuring high-temp liquid liquid level position.
Background technology
Existing common liquid level emasuring device, can be divided into active and passive type according to metering system, is mainly divided into utilizes magnetic force principle, static pressure differential pressure principle, reflection wave principle, electric capacitance change principle etc. according to application principle.
There is following limitation in existing liquid level emasuring device:, the limitation of Applicable media in the application, variety classes liquid level emasuring device has different requirement to Applicable media, such as resisting medium, oil product, fluidized state liquid, all likely make accuracy of measurement and sensitivity decline; Two, the limitation of Applicable temperature, as magnetic float level indicator, plate type level meter, glass-tube liquid level meter etc., because material limit, bearing temperature limitation is comparatively large, can not be used for the measurement of high-temp liquid; Three, the limitation of reaction velocity and accuracy, such as, capacitance level gauge is because the specific inductive capacity instability of fluid to be measured can cause error, and static pressure (differential pressure) formula liquid level gauge affects comparatively large by Media density and temperature, usually precision is poor; Four, the limitation of volume, the ball float volume as float type level gauge is comparatively large, occupies large quantity space in container; Five, the limitation of installation site, as float type level gauge adopts roof-mounted, can not adapt to the design feature of different vessels.
Utility model content
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of device of the measurement high-temp liquid liquid level position taking up room little.
The utility model solves the technical scheme that its technical matters adopts: the device of this measurement high-temp liquid liquid level position, comprise parallel electric heating tube and the thermopair of being located at container side wall sustained height, between the two apart from 2-5 centimetre, determine according to the viscosity of fluid to be measured and temperature conductivity, electric heating tube is connected by heat-conducting connecting at internal tank with thermopair.Heat-conducting connecting can according to the temperature of technique, corrosion-resistant needs, and adopt the material that temperature conductivity is high, such as copper, aluminium, the structure of heat-conducting connecting also can design as required.Heating tube and thermopair main working parts are in container inside, and heating tube connects one end of power supply, thermopair connects one end that teletransmission exports, at outside of containers.Thermopair connects temp controlled meter, and monitor temperature changes.
As preferably, the differing heights of described container side wall is provided with the some groups of measurement mechanisms be made up of electric heating tube, thermopair and heat-conducting connecting.
The effect that utility model is useful is: main element of the present utility model is electric heating tube, thermocouple temperature sensor and heat-conducting connecting, takes up room less, avoids using ball float to install, and takies the problem of larger space in container; Directly in container, measure liquid level, avoid plate type level meter, glass-tube liquid level meter etc. inside and outside be communicated with the liquid that may occur insulation, solidify, the problem such as viscosity increase, the simultaneously not proterties restriction such as liquid body viscosity; Quick and precisely, copper heat-conducting connecting heat conductivility is good for thermocouple temperature measurement, measurement data accurately, postpone little, avoid the coarse problem of level gauging; Electric heating tube uses high-temperature resistant shell, with copper sheet, thermopair, all can be used in higher temperature environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Description of reference numerals: container side wall 1, electric heating tube 2, thermopair 3, heat-conducting connecting 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment 1:
As Fig. 1, at the parallel installation electric heating tube 2 of the sustained height of container side wall 1, thermopair 3.At internal tank, electric heating tube 2, thermopair 3 are connected by heat-conducting connecting 4, heat-conducting connecting 4 uses width 1 centimetre, length 10 centimetres, the copper sheet that thickness is 1 millimeter.
During work, with firm power, electric heating tube 2 is heated, make it to keep steady temperature, produce the temperature difference with fluid to be measured; With the temperature electronic signal that control system monitoring thermopair 3 exports.
When fluid to be measured liquid level is positioned under measurement mechanism, the steady temperature of electric heating tube 2 measured by thermopair by measuring heat-conducting connecting 4.
When fluid to be measured liquid level rises, when not having measurement mechanism, heat-conducting connecting 4 is cooled or be heated to fluid to be measured temperature, and thermopair 3 measures fluid to be measured temperature.Known fluid to be measured liquid level meets or exceeds the height of measurement mechanism.
When fluid to be measured liquid level drops under measurement mechanism, the temperature return of heat-conducting connecting 4 is to steady temperature, and the temperature of heat-conducting connecting 4 measured by thermopair 3.Known fluid to be measured liquid level drops to below measurement mechanism height.
By the change of control system temperature data, obtain the information of fluid to be measured liquid level change.
Embodiment 2:
The many groups of measurement mechanisms be made up of electric heating tube 2, thermopair 3 and heat-conducting connecting 4 can be installed, as Fig. 2 at container side wall 1 differing heights.Often organize measurement mechanism and can measure temperature jump when liquid level did not have them, and can export with electronic signal, thus realize Inspect and control.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
