Level Measurement Overview

Level measurement is either contacting or non-contacting, measuring continously between the minimum and maximum range or at pre-determined points. Continous measurement usually uses ultrasonic or radar technologies while point measurement is usually contacting, float, paddle or vibrating blade switch.

Continuous Level Measurement

  • Measures continuously providing a control signal between minimum and maximum range.
  • Non-contacting, unaffected by contaminants or debris.
  • Ultrasonic or radar technology.
  • Choose radar when measuring volatile organic compounds.
