One of the most frequently used measuring appliance of industry, can measure to the liquid in open or closed container.Except gas blow pipe and tested Jie
Matter contact is outer, blowning installation and differential pressure（Pressure）Transmitter measuring cell is not all contacted with measured medium, so as to protect measurement
Element, reduces the maintenance of instrument, increased the reliability of measurement.Because blowning installation can ensure that constant flow rate gas is exported,
Differential pressure（Pressure）The pressure that transmitter is measured just can follow the change of gas blow pipe outlet pressure automatically, so, differential pressure（Pressure）
The signal of transmitter output just becomes corresponding relation with medium liquid level.Design parameter is generally：（1）Bleed pressure：0.4-0.8
MPa；（2）Pressure-reducing valve output pressure：0.2-0.4 MPa；（3）Recommend air blowing flow：20-3-40 L/H（With specific reference to live work
Condition）.Negative pressure lateral pressure：PL=P source of the gas+P tank, malleation measuring pressure：PH=P source of the gas+P tank+ρ gH, so can by differential pressure transmitter
To calculate to obtain liquid level H.
Blowing type liquid level meter in addition to it can measure the liquid level of clean liquid, be particularly suitable for mordant acid-alkali salt liquid,
The larger liquid of viscosity, easily-crystallized liquid, high temperature, the liquid level containing solid particle liquid.
The factor for causing blowing type liquid level measurement amount inaccurate：1. pressure guiding pipe material problem is measured, and original material is PP, and material is relatively
Soft, due to buoyancy in tank, or as tank body shakes（With self-circulating pump or with stirring tank be particularly acute）Cause
Malleation is surveyed PP tubing and floats into bending, or vacillates now to the left, now to the right, and causes the measurement of malleation measuring pressure unstable.2. blowning installation pipeline has leakage
Gas, causes positive/negative-pressure measuring pressure different, and measurement is not inaccurate 3. quantitative to ensure that positive/negative-pressure measuring pressure is consistent.
There is problem above, often cause that liquid level is indescribable significantly to be risen or fallen, the lighter causes operator
Member correctly cannot carry out reading to tank fill level；Heavy then due to interlocking effect cause whole production system to face parking danger.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, provides a kind of non-contact liquid level measurement amount auxiliary
Structure, prevents that non-contact measurement liquid level gauge is indescribable significantly to be risen or fallen, and causes operating personnel correctly right
Tank fill level carries out the defect of reading.
To achieve these goals, the technical solution of the utility model is：
A kind of non-contact liquid level measurement amount supplementary structure, including blowning installation, the pressure guiding pipe being arranged in container and impulse
The gas blow pipe of pipe connection, the pressure guiding pipe are zirconium pressure guiding pipe in parallel, and the gas blow pipe is two, be set up in parallel and respectively with
Zirconium pressure guiding pipe is connected, and the other end of two gas blow pipes is while be connected with a differential pressure transmitter, described air blowing fills
The outlet side that puts is connected in parallel two arms, and two arms are respectively communicated with two gas blow pipes, on each arm
Permanent flow valve and flowmeter is arranged in series, the permanent flow valve is located at the one end near blowning installation, the flowmeter is located remotely from
One end of blowning installation.
Used as the improvement to technique scheme, the flow is calculated as suspended body flowmeter.
Used as the improvement to technique scheme, the port of export of the blowning installation is provided with filtering pressure reducing valve, described blows
Device of air is connected with two arms after filtering pressure reducing valve.
Compared with prior art, the beneficial effects of the utility model are：
Non-contact liquid level measurement amount supplementary structure of the present utility model, 1, transform pressure guiding pipe as not only anti-corrosion but also hard zirconium
Pressure guiding pipe processed and it is arranged in parallel, so as to avoid pressure guiding pipe from bending in container or dancing, in the middle of zirconium pressure guiding pipe no
Weld seam, global formation, reduces the hidden danger point of corrosion air-leakage；2nd, antirust varnish is smeared in outside blowning installation and pipeline external, prevent
The blow gas pressure that only pipeline gas leakage causes is forbidden；3rd, install suspended body flowmeter on the spot on positive/negative-pressure gassing pipe additional, ensure pipe
In the case of line is gastight, by adjusting flow scale in suspended body flowmeter, and control positive/negative-pressure is coordinated to survey air blowing with permanent flow valve
Amount, so as to the blow gas pressure that quantitative control positive/negative-pressure is surveyed, it is ensured that the precision of measurement；4th, two pressure guiding pipes of differential pressure transmitter equilibrium
Gas pressure, such that it is able to mutually revise to measurement data, it is ensured that the accuracy of data.
