Description

A kind of contactless level meter measuring device

Technical field

It the utility model is related to level gauging field, and in particular to a kind of contactless level meter measuring device.

Background technology

Ultrasonic wave or radar levelmeter are largely used in the measurement of level meter in Industry Control at present, in reality During production and application, level meter has certain probability measured value inaccuracy, the even failure such as saltus step, bad value occur, and analyzing it can The reason for energy, is as follows：

If measurement to be medium that solid particle carries airborne dust property in storage tank when, due to the presence of airborne dust in tank body, One layer of grey film can be formed in the course of time in level meter probe positions adsorbent solid particle.Between ultrasonic wave or contactless thing The measuring principle of position meter is to launch the acoustic measurement close echo time at probe, so as to directly affect the measurement of level meter.

If measurement for be liquid in storage tank with volatilization property or high temperature medium when, since tube body weight liquid medium is waved The presence of hair, can adsorb in level meter probe positions and be condensed into fluid film, so as to directly affect the measurement of level meter.

This can either way cause level gauging value inaccuracy, the even failure such as saltus step, bad value occur, if important Interlock condition can then seriously affect the progress normally produced.

Utility model content

To reach above-mentioned purpose, the utility model is implemented according to following technical scheme：

A kind of contactless level meter measuring device, including level meter, suspended body flowmeter, one way stop peturn valve, filtering decompression Device, regulating valve, source of the gas and air supply pipe, are connected between the level meter and reactive tank by pipeline, setting and level meter among pipeline Pop one's head in opposite interface, between source of the gas, filtering pressure reducer, one way stop peturn valve, regulating valve, suspended body flowmeter and reactive tank and level meter Pipe joint is sequentially connected by air supply pipe, and the one way stop peturn valve limitation gas can only flow to regulating valve from filtering pressure reducer.

Further, the source of the gas is source nitrogen.

Further, the air supply pipe uses stainless steel.

The beneficial effects of the utility model：It can prevent solid dirt particle from tiring out the purging that level meter is popped one's head in by gas Product, is also possible to prevent liquid and condenses film forming in level meter sensor surface into medium, extend ultrasonic wave or contactless thing position The stability of the service life increase measurement of meter；In addition, the defeated of gas can rationally be controlled by suspended body flowmeter and regulating valve Enter amount.

Embodiment

One embodiment of the utility model is described further below in conjunction with the accompanying drawings.

A kind of contactless level meter measuring device as shown in Figure 1, including level meter 2, suspended body flowmeter 4, regulating valve 5th, one way stop peturn valve 6, filtering pressure reducer 7, source nitrogen 8 and stainless steel air supply pipe, pass through pipeline between level meter 2 and reactive tank 1 Connection, pipeline centre is set and level meter 2 is popped one's head in opposite interface, source nitrogen 8, filtering pressure reducer 7, one way stop peturn valve 6, adjusting Valve 5, suspended body flowmeter 4 and pipe joint are sequentially connected by stainless steel air supply pipe 3, and one way stop peturn valve 6 limits nitrogen can only be from Filtering pressure reducer 7 flows to regulating valve 5.

When the utility model is used, nitrogen subtracts after the entrance stainless steel of source nitrogen 1 air supply pipe 5 by filtering pressure reducer 7 Pressure, one way stop peturn valve 6 purge the probe of level meter 2 after limiting direction, avoid 2 transducer probe face of level meter from forming ash Dirt medium or condensed fluid dielectric film, suspended body flowmeter 4 can detect the flow of nitrogen in air supply pipe 3, and coordinate adjusting Valve 5 is adjusted, and the flow of nitrogen is rationally controlled on the premise of purging effect is ensured.

The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above, it is right For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and is not carrying on the back In the case of from the utility model essential characteristic, the utility model can be realized in other specific forms.Therefore, no matter from which From the point of view of a bit, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the utility model is by appended power Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling Change is embraced therein.Any reference numeral in claim should not be considered as to the involved right of limitation will Ask.

Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical solution, this narrating mode of specification is only that those skilled in the art should for clarity Specification is regarded as into an entirety, the technical solutions in the various embodiments may also be suitably combined, forms people in the art The other embodiment that member is appreciated that.
