"There are many applications involving level measurement in process plants. There are various types of level sensors available for this purpose. It is very difficult, to find out the perfect choice. To meet the specific needs of an application, either for liquid or solids in any container, one must take into account the physical/chemical properties of a substance in question.
• How to select right measuring technology
All level measuring instrument is based on certain characteristics of the process material, such as density, pressure, temperature, etc., and its suitability for the same is to be taken into consideration. One can narrow down the options by considering the following factors before selection of right level sensor for level measurement and its suitability.
1) Applications/ Purpose of Level Measurement -
a) Visual Indication:-Various types of Techtrol make level gauges can be used for visual indication only, where the electrical output is not required.
2) Service Medium whose level is to be measured–
It can be liquid, slurry, interface level of two liquids with different densities or powders/ granules.
3) Operating Conditions-
Minimum and maximum operating temperature & pressure conditions within the tank must be known for the selection of right level sensor for level measurement.
