 Precision Water Level Instrument
Unidata Precision Water Level Instrument

Product Features
 
  • Unidata Precision Water Level Instrument are most accurate way to monitor the level of a water surface.
  • Achieve an operating accuracy and resolution of 0.2mm.
  • Normally connected to the water surface by a float system.
  • As the water level changes, this rotates the input shaft on which is mounted an optical encoder.
  • Display the water level on its LCD screen.
  • The encoder is continuously monitored and the instrument tracks any water level changes.
  • These changes update the LCD screen and the displayed reading can be recorded by an associated data logger.
  • The very low mechanical friction and inertia of the instrument produce data of high precision and accuracy.
  • A replaceable battery pack powers the instrument for more than 1 year.
