The float of the magnetic flap level gauge is damaged
Thread Content
Dear colleagues, the magnetic flap level gauge installed at our ethylene compression unit is giving inaccurate readings. Upon inspection, it was found that the float was severely deformed and had a crack in it. The working medium is liquid ethylene, with a pressure of 1.4 MPa and a temperature of -35°C. I would like to ask if any of you have encountered similar issues with magnetic flap level gauges used in low-temperature environments What are some other possible reasons for the damage to this float? Thank you!
A deflated or cracked float is usually due to insufficient strength of the float; this phenomenon occurs after long-term use (sometimes even after it has already been put into operation). Additionally, overpressure can also cause this fault.
It is generally caused by thermal fusion.
When you encounter them often, just replace them; don’t overthink it. The requirements for materials are getting higher
Material issue? Were the environmental conditions specified during the initial selection? If so, try using a different material or level gauge
The strength isn’t sufficient; this should be the responsibility of the manufacturer, who should carry out calculations and make selections based on the medium, temperature, and pressure conditions.
It’s broken; it’s just white now, because you’ve used it until it broke. . . Does it even need to be asked? . Asking out of ignorance, then. . If it gets worn out, should I replace it? If you keep using them indefinitely, how can the manufacturers of these flip panels make a living? Spread love. :P.
The voltage tolerance is insufficient; replace the float.
You buy the instrument you use; it’s up to you to decide what to choose and what not to choose, not the manufacturer. . . It’s from an instrument manufacturer; it’s just a reference suggestion for you. . . If you can’t choose or use the instruments properly, and then you shift the responsibility for your inability to use them correctly onto the manufacturer… haha, you really are good at finding clever ways to take shortcuts. . . . . . Well, let me ask you a small question. If you take the matter to court, how will you prove that it was the manufacturer’s fault that caused the float ball to crack or deflate, and not your own improper use?
Okay. Our low-temperature ethylene level gauge has been in use for over a decade without ever breaking down. A set of Tokyo Keikaku level gauges. I have encountered such a problem in other work sections as well – the float suddenly shoots upward. When struck on the upper part of the connector, it deforms directly and gets stuck, preventing it from moving downward. It’s not just a matter of the float’s mass; sometimes operating conditions can also cause damage to the float.
I have indeed encountered situations where the float had minor cracks and the medium seeped into it, but such severe deformation is a bit exaggerated
