Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space, and to provide electrical output about these measurements that are proportional to the input level.  Level transmitters are designed to measure level based on either a point level or continuous level readings.  Point level transmitters provide output when a specific level measurement is reached.  This output is generally in the...

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using level transmitters?
7 answers
Answers:
Eeeeemmmmm...Only basic recommendations... ultrasonic transmitters could be used to measure inside tanks with hot liquids, but a high power signal instrument shall be used... Same when too much dust is in the air... however, in this cases radar transmitters work better. Hydrostatic measurement could be used only if density is known and doesn't change... Ultrasonic transmitters work properly inside vertical pipes (for tanks), but usually you must adjust echo suppression for valves mounted in the same pipe, or for the tank's connections...
~Carlos S., Engineer, Santiago, Chile
