Selecting Ultrasonic Level Sensors

The main questions which need to be considered before selecting a level measurement sensor:

  • What are the contents being measured – liquid or solid or slurry or powder?
  • Are level measurements required either continuous or point level (discrete)?
  • What are the application’s minimum and maximum temperature and pressure?
  • What level measurement range is required?
  • What accuracy range is required?
  • Is it possible to penetrate the vessel wall or be inside it?
  • If liquid, is there any turbulence, foam or vapour at the surface?
  • Is an integral display or remote display required?
  • What kind of output / alarms are required eg analogue, relay, etc ?
