Description
Technical field
This utility model relates to technical field of measuring equipment, specifically a kind of self-resetting type liquidometer.
Background technology
The height of liquidometer liquid medium in a reservoir is called liquid level, measures the instrument of liquid level liquidometer, and liquid level is calculated as the one of level meter.
In actual liquidometer application, the measurement of sewage and suspension, easily cause the machinery external environment influence such as jam, blocking, measurement error can be produced big, liquidometer often can not meet the problems such as in-site measurement needs.
Existing liquidometer there is also a lot of shortcoming, as:
Connected vessels type liquidometer, is apply the most common gauge glass, simple in construction, inexpensive, directly perceived, is suitable to onsite application；But cracky, inner surface easily stains, and can cause reading difficulty, is not easy to operating and regulates.
Radar level gauge, is the mode of operation adopting and launching reflection receivable.Electromagnetic wave launched by the antenna of radar level gauge, these ripples are after measurand surface is reflected, being received by the antenna, electromagnetic wave is directly proportional from the time being transmitted into reception to the distance to liquid level, and relational expression is as follows again: D=CT/2 (D: radar level gauge is to the distance of liquid level；C: the light velocity；T: electromagnetic wave runs the time), the time of radar level gauge recording impulse ripple experience, and electromagnetic transmission speed is constant, then can calculate the liquid level distance to radar antenna, thus knowing the liquid level of liquid level.Do not need transmission medium, the feature not affected by volatilization mist in air, steam, groove, the level gauging of volatile medium can be used for.Adopt non-contact measurement, the not impact of the physical characteristic such as the density of liquid, concentration in groove；But, radar level gauge is expensive, and instrument needs the parameter arranged more, once go wrong, be generally difficult to find is that what reason causes, also can report an error if antenna itself is stained with medium accidentally, also can report an error if any crystallization icing phenomenon, need heating and thermal insulation to process, and clear up antenna, initial installation needs to be hole capital after selling all securities, and namely empty material level, bothers very much.
Magnetic float level indicator, it is develop according to law of buoyancy and magnetic couplings effect, when the liquid level in tested container lifts, magnetic float in liquidometer body tube also lifts therewith, permanent-magnet steel in float is delivered to magnetic column indicator by magnetic coupling, drive red, white turned column overturns, when liquid level rises, turned column is changed into redness by white, when liquid level declines, turned column is changed into white by redness, the actual height that red white intersection is internal tank liquid level of indicator, indicate clearly thus realizing liquid level, magnetic float level indicator can accomplish high sealing, anti-leak and be applicable to high temperature, high pressure, corrosion resistant occasion.To high temperature, high pressure, poisonous, harmful, strong corrosive medium its superiority more aobvious；But, magnetic float level indicator and physical contact between media, floater seal requires strict, can not measuring resisting medium, magnetic material is easily caused liquidometer cisco unity malfunction such as demagnetization, and turnover panel is easily stuck, causing and cannot teletransmission indicate, magnetic material is easily caused liquidometer cisco unity malfunction such as demagnetization.
Pressure-type liquidometer, is that the pressure utilizing uniform liquid converts liquid level to the relation being highly directly proportional by measuring the pressure of liquid bottom.P=ρ gh (P pressure)；Density according to measured medium and liquid measure range computation go out pressure differential pressure scope, the more suitable Pressure gauge of the performance such as selected range, degree of accuracy or differential pressure gauge；But owing to it is affected very big by Media density and temperature, so usually ratio of precision is poor, and be eliminate these impacts, need a lot of other test instrumentation, it is significantly high that result builds a set of perfect static pressure measurement system price, owing to the static pressure of fluid column is directly proportional to liquid level, just can record liquid level hence with the static pressure of fluid column on gauge measurement datum level, universal scope is wide, it is easy to calibration.
