Did you know that some minerals and metals aren’t attracted to magnets at all? One example is zinc. What currently holds our planet’s atmosphere is actually a magnetic field!
All of this is rather interesting and might make you wonder what magnetic instruments are and why you should use them. There are various types of transmitters and you might be curious which is right for your operation. Read this guide on how magnetic level transmitters work and why they’re so beneficial today!
What Is the Magnetic Level Indicator Working Principle?
Your underground magnetics have the same fluid as the vessel. Your level indicator is attached to the vessel and connects directly to it.
In the magnetic level transmitter’s chamber, you have a float with a magnet assembly inside. When the fluid falls or rises, the float will as well.
When the float moves, the magnet assembly will rotate. This changes the visual indicators outside of the chamber from one color to another.
Your magnetic level measurement transmitters rely on the interaction between the magnets. Due to this, they don’t need a power source.
The magnetic force can also have an impact on transmitters outside of the chamber. There’s easy reading as well since the colored flags are easy to see.
Further Understanding Magnetic Level Transmitters
Liquid level sensors have 2 broad types. Continuous level sensors are used for processes when the levels fluctuate and you need an accurate measurement. Point level sensors can tell when a liquid reaches a certain level.
The factors that decide which type is right for you include viscosity, chemical composition, density, etc. For a float level sensor, choose a magnetostrictive level transmitter. Other types include submersible pressure transducers, ultrasonic sensors, and radar transmitters.
Why Use Magnetic Level Transmitters?
The mechanics of these instruments are effective and simple to use. They’re also incredibly reliable.
If you’re looking to continuously measure fluid levels, they’re great to use. Many choose them since they’re maintenance-free and don’t require power. This means that you can use them across a variety of different industries.
Magnetic level transmitters are also accurate. You can also enjoy the fact that there’s minimal effort in calibration. Their capabilities also can’t be matched by competing technologies.
Levels are determined based on the time that lapses between the reflected return signal and the initial transmission. Foam and other environmental factors shouldn’t negatively affect the technology either.
Understanding Magnetic Instruments and How They Work
After exploring this guide, you should have a better idea of magnetic instruments and how they work. Take your time deciding if it’s right for your operation and processes. Remember that it’s a great choice when you’re looking for accuracy when it comes to measuring liquids.
