Level measurement in glass-lined reaction vessels
Thread Content
Original glass-lined reactor, with stirring. The medium is viscous. Temperature: 60°, pressure: 0.1 MPa, flange size: DN100, height of the reactor: 2300. I really don’t know how to choose a level gauge for this setup Are there any solutions recommended by experts?
Add more viewports! Or use a single-flange level gauge!

Use the SICK twin sensors for a differential level gauge – for the liquid phase, use an immersion-type sensor with a probe that is not in contact with the liquid; for the gas phase, use a detachable probe. Do you know about SICK? I don’t know if I should tell you, but Shuaike is just our little crappy factory :lol. . . Measuring liquid level is a piece of cake; measuring density, on the other hand, is a real challenge. Back in those days, Jiangsu Kuaida Agrochemicals was struggling greatly with determining the density of toluene in enamel tanks – even the design institutes were stuck on this problem. Eventually, they turned to me. And so, our SC65 submersible online density meter from that small factory of ours was dropped down through a tiny hole at the top of the enamel tank, solving this intractable problem and relieving their urgent need. :lol Want to know if it works well? It works just as well as several shovels when digging; it doesn’t give false readings and doesn’t lose strength. I’ve purchased it many times already. No pictures, no truth – here are the pictures!
Starting from the opening at the top of the tank, first insert a sleeve, and then lower the probe down through that sleeve – in this way, the effects of mixing and disturbance are prevented..... Divider line--------------------------------------- In enamel tanks, there is no opening left for use in the liquid phase, and it’s certainly not allowed to make cuts or holes to weld flanges; this is common sense. The following 1000000000000000000000000000000000000000000000000000000........... characters are omitted

Neither single nor double flanges can be used: first, glass lining does not allow for openings to be made, and second, viscous media can cause the pressure diaphragm to stick together.
If the stirring blades are at the bottom of the container, a non-contact radar level gauge installed at the top can be used; in that case, the liquid level at the bottom portion need not be measured； If the material of the mixing blade is non-metallic, ignore the interference caused by the mixing blade directly ； If the mixing blades are made of metal, and if they are arranged in upper, middle, and lower layers or if the blade diameter is large, it is recommended to install a measuring tank on the side of the storage tank; the radar level gauge can then be placed on top of this measuring tank ； Under temperature and pressure conditions, contactless ultrasonic level gauges are excluded as well. Media with viscosity, contact-type float level gauges, magnetic flap level gauges, and capacitive level gauges are also excluded directly ； If the density remains stable, a double-flange differential pressure transmitter can also be considered.
