The weighting type interface meter can adopt weighting type to measure interface indirectly, having simple operation, reliability and stability, and can overcome the defect of the prior interface meters which demand the measurement components to contact the measured medium and require large measurement range of the measured interface. The utility model is suitable for the equipments which indirectly measure liquid interface.
Description
Technical field
The utility model provides and is widely used in two kinds of metering devices that the immiscible liquid medium interface is measured, specifically Weighing type level meters in the measuring vessel.
The background skill
The most frequently used in existing interface level measurement have float bowl-type level meters, differential pressure type level meters etc., these several measurement instruments must use (generally surpassing 300mm) in the wide range scope, measuring sensor all must directly contact with medium, this with regard to the structural behaviour that requires instrument itself must be according to the measuring media temperature, pressure is different and dispose.
Summary of the invention
In order to overcome the shortcoming of existing level meters, the utility model provides a kind of Weighing type level meters.These level meters solve the technical matters of interface level measurement by the mode that measurement mechanism is weighed.
The scheme that the utility model technical solution problem is adopted is: the body of weighing that is provided with the Weighing body end socket is suspended on the fixed support body by weigh supporting plate and LOAD CELLS, be connected with the outlet of slagging pipe in the lower end of the body of weighing, the upper end is connected with the bleeder pipe outlet, top in body one side of weighing is connected with the light constituent inlet pipe, the bottom is connected with the heavy constituent inlet pipe, LOAD CELLS is installed in weighs between supporting plate and the fixed support body, and be connected with the converter of weighing by cable, on the converter of weighing, be provided with communication interface.
The utility model can be measured material interface indirectly by weighing, and is simple to operation, reliable and stable, and the measuring sensor that has also overcome existing interface level measurement instrument must contact with measured medium and the necessary enough big shortcoming of the measurement range at measured interface.The suitable instrument of under various conditions liquid surface being measured is indirectly used.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure, the body of 1. weighing, the body end socket of 2. weighing, the supporting plate of 3. weighing, 4. LOAD CELLS, 5. bleeder pipe outlet, 6. light component inlet pipe, 7. heavy component inlet pipe, 8. slagging pipe outlet, 9. fixed support body, the converter of 10. weighing, 11. cables, 12. communication interfaces.
Embodiment
The body 1 of weighing that is provided with Weighing body end socket 2 is suspended on the fixed support body 9 by weigh supporting plate 3 and LOAD CELLS 4, be connected with slagging pipe outlet 8 in the lower end of the body of weighing, the upper end is connected with bleeder pipe outlet 5, top in body one side of weighing is connected with light constituent inlet pipe 6, the bottom is connected with heavy constituent inlet pipe 7, LOAD CELLS 4 is installed in weighs between supporting plate and the fixed support body, and is connected with the converter 10 of weighing by cable 11, is provided with communication interface 12 on the converter of weighing.
Light component inlet pipe is connected with the light component of tested container medium.
The heavy component inlet pipe is connected with tested container medium heavy component.
Measured medium does not contact with detecting element.
Communication interface is connected with numeral or analogue communication device, can be connected with remote display device or transmit.
The body of weighing is interior for having the cavity volume in space.The upper and lower unanimity of intracavity diameter of the middle measure portion of body of weighing, the upper and lower unanimity of outer wall thickness.
The pipeline that is connected with tested container all adopts flexible pipe to connect.
The utility model course of work:
Install:
Body top and the bottom connector is connected with light, the heavy component side of tested container respectively by flexible steel in flat section tubing with weighing.
The body of will weighing is suspended on the fixing support rack by weigh supporting plate and LOAD CELLS, and the weight of the body of weighing is vertically acted on the LOAD CELLS by the supporting plate of weighing.
LOAD CELLS is connected by cable with the converter of weighing.
Use:
1, measures preceding the preparation: discharge the gas that may occur in the Weighing body by atmospheric valve, discharge the slag that enters in the Weighing body by the outlet of slagging pipe.
2, level meters are demarcated: be full of light weight fluid in the Weighing body, adjust the converter zero point of weighing, make the converter of weighing be output as " 0 "; The converter of weighing is full of heavy liquid, adjusts the converter range of weighing, output 100%.
3, after the demarcation through 0% at above-mentioned interface and 100%, level meters just can come into operation, by to the weighing of weighing apparatus body, can between be connected on determine two kinds of different specific weight media in the tested container in the output of the converter of weighing the interface just.Carry out information transmission by the converter of weighing, can implement the tested container interface control as required.
Measure the interface of two kinds of liquid mediums indirectly with weight method.Two kinds of liquid mediums enter in the body of weighing, because proportion difference, claim the weight of the body of the weighing quantity of indirectly representing two kinds of liquid in the body of weighing, to occupy separately, owing to weigh in the body from top to bottom inner wall smooth, inside dimension is unanimous between the higher and lower levels, outer wall thickness is unanimous between the higher and lower levels, therefore can measure two kinds of liquid surfaces indirectly.
The utility model only is that the body of weighing contacts with pressure transducer, it only is equivalent to a container and links to each other with survey sensor, its measuring sensor and converting member are fully and measured medium is contactless, the measurement range at interface can be little of 10mm, satisfied the requirement of all interface level measurements.
