Types of Level Transmitters
There are various types of Level Transmitters.
Have you ever thought you understood characteristics of each model, but when it came time to choose a model, you were confused as to which one to choose?
For those people, here we will explain not only types and features of Level Transmitters, but also their disadvantages.
At the end, we have prepared a quick reference table for model selection, so please use it.
Not only do Level Meters have different methods, but each manufacturer also has its own features.
It is necessary to consider major conditions such as physical properties, measurement environment, installation conditions, and external disturbances when making a selection.
Raw materials and products come in various states such as bulk, granular, powder, liquid, slurries, and deposits in liquid, and there are many measurement methods that take into consideration physical properties and environmental factors.
Additionally, Level Meters can be roughly divided into two types: methods that measure the empty distance from tank ceiling to object to be measured, and methods that directly measure storage level of the object to be measured.
Level meters that measure air distance are sounding, ultrasonic, microwave, laser distance meter, guide rope type, liquid level meter, and displacer.
Capacitance, pressure, and differential pressure gauges directly measure storage level.
Here, we will introduce principles, features, and disadvantages of each method, focusing on measuring powder, granular, and bulk.
