Description

Anticorrosive floating ball lever meter
Technical field
The present invention relates to liquid level gauge, particularly relate to a kind of anticorrosive floating ball lever meter of application in glass (or quartz) Distallation systm (or reactor).
Background technology
In recent years, liquid level gauge is widely used in automation field, but but there is not the purity requirement of can work in Korrosionsmedium for a long time, meet rectification process or high-purity reaction in the market and can be installed in glass (or quartz) cucurbit (or reactor) by easily airtight the liquid level gauge realizing medium liquid level continuous fine and really measure.
In current market product, liquid level gauge mainly contains following a few class: magnetic flap level gauge, capacitance liquid level meter, RF Liquid Level Instrument, static pressure called putting-into-type liquid level meter, radar level gauge, infrared ray liquid level gauge, ultrasonic level gage, floating ball lever meter.But for outside need heating, volume medium kind that is little, distillation/fractionation (or reacting) is many, temperature is high and complete hermetic glass (or quartz) cucurbit (or reactor), it is all very poor that the first seven plants product applicability: magnetic flap level gauge need side to be arranged on glass (or quartz) Distallation systm (or reactor) outward, and installation foot need lower than surveyed minimum liquid level on the downside of it, because there is heating arrangement (as electric jacket) cucurbit (or reactor) outside, this liquid level gauge cannot be installed and used; Capacitance liquid level meter utilizes the change of electric capacity to carry out measuring media liquid level, for the low-down glass of electrical conductivity (or quartz) cucurbit (or reactor), auxiliary electrode need be installed, and transmitter volume is larger, weight reaches 2 ~ 3Kg, for glass (or quartz) cucurbit (or reactor) that load-bearing is poor, over-burden; RF Liquid Level Instrument is applicable to single medium level gauging, all needs to re-start calibration to liquid level gauge when changing cucurbit (or reactor) interior medium at every turn, and inconvenient user uses; Static pressure called putting-into-type liquid level meter heat resisting temperature is general only at about 80 DEG C, cannot meet the distillation/fractionation of high boiling medium or the reaction high to temperature requirement; Radar level gauge heat resisting temperature can reach 300 DEG C, but it measures blind area comparatively greatly, is unsuitable for small-range level gauging; Infrared ray liquid level gauge and supersonic liquid level count non-contact measurement, but cannot use when having steam to exist, and namely cannot be used in airtight Distallation systm (or reactor).
Floating ball lever meter for measuring sensor with magnetic ball float, by the magnetic coupling interaction between magnetic reed switch and high-temperature resistant ring-shaped magnet, makes the linear change of resistance in liquid level gauge, then by transmitter, resistance variations is converted to the standard current signal of 4 ~ 20mA.Floating ball lever meter is lightweight, entire outer diameter is less and heat resisting temperature can reach 150 DEG C, the most important thing is, because ball float has constant weight, when measuring the liquid level of boiling medium, measurement result fluctuation range is little, so be very applicable to the use of Distallation systm (or reactor).But, current floating ball lever meter is many to be made by stainless steel, mounting means mainly contains screw thread installation and flange installs two kinds, for high-purity distillation or require the high and Korrosionsmedium environment of reaction medium purity, stainless steel long period of soaking in media as well, easy damage, not only reduce the serviceable life of liquid level gauge, and may interfering material be introduced, thus affect rectifying or reaction effect, in addition, the screw thread of stainless steel or flange are difficult to be tightly connected with glass (or quartz) cucurbit (or reactor), in order to solve corrosion resistance and interference problem, current way is in stainless steel skin plating Teflon material, but Teflon itself belongs to organism category, to organic solvent or the strong medium of corrosivity still exist introduce interference may, especially the control of extraordinary high-purity solvent liquid level in glass (or quartz) cucurbit (or reactor) can not be used to.
