Are there any magnetostrictive level gauges used to measure levels? Come in and let’s discuss it together
Thread Content
The level measurement using magnetostriction is calculated based on the current generated, but a prerequisite for this is that the float must move. Since it is limited by the movement of the float, could there be significant errors in the level measurement? Since the several setups I’ve worked with didn’t use this type, I’m asking those who do use it to discuss whether this boundary detection function is used frequently What is the accuracy?
A comparison was once made with guided wave radar; the error of guided wave radar was around 5 mm, while that of magnetostrictive sensors was below 3 mm
As long as the float is chosen correctly, the results are good!
Measuring interfacial magnetostriction is a good option; as long as the medium being measured is not too viscous and it does not interfere with the proper functioning of the float, this method works perfectly. Using two floats allows for the measurement of both the interface and the liquid level.
It seems this one is pretty good; I’ll choose this from now on
The accuracy is pretty good; as long as the medium is clean, that’s fine
For measuring interfaces, radio frequency admittance is the preferred method, as it determines the interface by measuring the dielectric constant (this method cannot be used when the difference in dielectric constants is small). Magnetostriction measures the interface based on density differences; however, in some applications the density difference is very small, making this method less effective. Of course, it’s possible that magnetostriction works well in certain situations. There are too many fake radio frequency admittance meters available in China; they are not genuine radio frequency admittance meters. Domestic products can only measure up to 5-6 meters, while the IDEAL meters that we distribute from the UK are capable of measuring up to over 20 meters. This product was initially introduced to China along with foreign process packages. Currently, our company specializes in producing their level measurement products; you can get in touch with us for technical discussions at 132=5670=6769
There’s no need to focus on precision at the measurement interface; generally, this is used for process control and qualitative analysis, and what matters is the range of the liquid level. Furthermore, under normal operating conditions, when the liquid level fluctuates back and forth, stability, sensitivity, and resistance to interference should be given more attention.
It has significant limitations; magnetostriction is not a universal solution. The density values provided by design firms are not necessarily accurate, and moreover, a small difference in density makes it difficult to use effectively. The interface can use radio frequency admittance (true radio frequency admittance; there are too many fake versions), but of course this comes with certain conditions: the dielectric constants need to differ significantly; otherwise it won’t work well. Nothing is universal; don’t idealize any product. There is only a matter of whether it’s suitable or not, not a distinction between good and bad.
Thank you. What I meant by choosing this is that it’s suitable for the medium I use at the moment
