• OVERVIEW

  The Model 6541C Precision Water Level instrument can achieve operating accuracy and resolution of 0.2mm. This accuracy is maintained for the service life of the instrument without calibration or maintenance, apart from battery changes.

  This instrument has the range to monitor surface and underground waters, and the precision to monitor rainfall and evaporation.
  The instrument is normally connected to the water surface by a float system. As the water level changes, the input shaft rotates. An optical encoder is mounted on the input shaft. On installation, the instrument is set to display the water level.

  The encoder is continuously monitored as the instrument tracks water level changes. These changes update the LCD display and the readings can be recorded by an associated data logger.
  The very low mechanical friction and inertia of the instrument mean that it can produce data with high precision and accuracy. A replaceable battery pack powers the instrument for more than six months. A practical design and rugged construction ensure easy operation and long service life.
