Description
Technical field
A kind of automation control system is the utility model is related to, concretely relates to a kind of ultrasound for adapting to water level fluctuation
Ripple water-level gauge.
Background technology
The normal operation of ship lock be unable to do without to be measured the waterlevel data of upstream, lock chamber, downstream etc. in real time, with ship lock pipe
The automating of reason, few water-level gauge such as peopleization, conventional mechanical, ultrasonic wave hinder for some reason compared with it is frequent, service intervals are short, precision is poor
The problems such as needing personnel's regular calibration, it can not increasingly adapt to the trend of ship lock Informatization Development.Therefore need badly a kind of comprehensive
A variety of water-level gauge advantages are closed, unattended is realized, corrects automatically, adapts to a variety of regimens, the multimode water-level gauge of long-term stable operation,
To substitute existing ship lock water-level gauge.
The analysis of prior art and compare：Conventional water-level gauge mode has following several：Laser water-level gauge, ultrasonic water level
Meter, indicator water gage, magnetic float water-level gauge, static pressure type water-level gauge, servo-type water-level gauge etc..Can be with for from measuring principle
It is divided into contact type measurement and non-contact measurement, the measurement of pressure type principle etc..

Magnetic float in meter body tube also lifts therewith, so as to realize that liquid level clearly indicates.Magnetic float water-level gauge can be accomplished
High sealing, anti-leak and suitable for high temperature, high pressure, corrosion resistant occasion.To high temperature, high pressure, poisonous, harmful, strong corrosive medium
Its more aobvious superiority.Shortcoming：Magnetic float water-level gauge and physical contact between media, floater seal requirement are strict, it is impossible to which measurement is viscous
Property medium.Magnetic material is easily caused water-level gauge cisco unity malfunction such as demagnetization, and turnover panel is easily stuck, and causing can not teletransmission instruction.
Magnetic material is easily caused water-level gauge cisco unity malfunction such as demagnetization.
5th, static pressure type water-level gauge：It is using the pressure of uniform liquid to highly directly proportional relation by measuring liquid bottom
Pressure convert liquid level.P=ρ gh (P pressure)；Pressure is gone out according to the density of measured medium and liquid measure range computation
Or pressure differential range, then the suitable pressure gauge of the performance such as selected range, accuracy or differential pressure gauge.Shortcoming：Because it is by Media density
Influenceed with temperature very big, so usually precision is poor, and be to eliminate these to influence, it is necessary to a lot of other test instrumentations, as a result
It is very high to build a set of perfect static pressure measurement system price.Because the static pressure of fluid column is directly proportional to liquid level, therefore utilize pressure gauge
The static pressure of fluid column can measure liquid level on measurement datum.It is wide to popularize scope, easily calibration.
6th, servo-type water-level gauge：It is that more successful novel water level meter, the high accuracy for being mainly used in light oil product are surveyed recently
In amount.Stronger competition is formed with indicator water gage.The identical steel band type water-level gauge of general principle, but with accurate power sensing
Device and servo-drive system, closed-loop regulating system is formed, by considering steel band self gravitation, accurately adjust float height to reach
Neutral buoyancy and gravity, accurate current fluid level are obtained to tank deck height, to obtain level value.Pyroelectric technology alliance precision is high,
1mm can be reached, meet metering level requirement.It is used in the lightweight non-corrosiveness liquid of calmness.Shortcoming：Installation and debugging are number
It is tired, equally there are the various unfavorable factors of contact water-level gauge and price is high.
