Seeking help with level measurement
Thread Content
Hello everyone. There is a question here: how should one measure the level of a viscous and corrosive substance in a closed container? What method should be used for this purpose? It is also possible to determine high and low levels by only outputting digital signals.
It is recommended to use an ultrasonic level gauge or radar, which are non-contact methods
A float level switch can be used; it’s inexpensive and easy to apply.
Using a radar works better, but be careful with the selection of the radar. It is recommended to use SABB
A capacitive level transmitter can be used, as long as the material does not cause sticking issues on polytetrafluoroethylene.
I don’t know how high the temperature will be; a tuning fork switch is also an option, and it’s not expensive either
Given its high viscosity and strong corrosiveness, it is best to use a contactless method; ultrasound or radar should be the first choices
It is recommended to use a contactless level gauge. Using ultrasound or radar
If the temperature and pressure are appropriate, it is recommended to use radar or ultrasonic level gauges for measurement.
Nuclear level gauges or switches could also be considered. I think the information provided by the original poster isn’t very comprehensive; providing a diagram of the container along with details on its temperature and pressure would help in making a suitable selection
The poster could provide more detailed parameters: what is the viscosity? What is a medium? Temperature and pressure? What is the structure of the tank? Generally speaking, ultrasonic or wide-band radar type level switches should be used; for other applications, more detailed parameters are required!
The SABO radar is good, at a metrological level, but the price seems too high! I guess the original poster doesn’t use a radar with such high precision
Given the high viscosity, contact-based methods such as float balls and tuning forks should be ruled out; it is recommended to use ultrasonic or capacitive methods
The original poster is being too vague – how specific is the viscosity? How corrosive is it? It is irresponsible to require the selection of certain instruments without specifying these conditions! Choosing a radar level gauge blindly can result in unnecessary expenses.
Nuclear level gauge; level switch – victory is the best choice:
I agree with the view from floor 16, but using nuclear level gauges is mainly problematic due to the complicated procedures required, as well as environmental impact assessments and other subsequent issues – it’s quite troublesome.
