BaroTROLL Atmospheric Pressure Sensor
Barometric pressure applies a direct stress upon open wells and surface water. Locally, barometric effects can change
significantly from location to location as a result of topographical and micro-meteorological changes. Therefore, it is important
to compensate for the barometric pressure changes when monitoring water elevation.

Configuring Depth and Level for PLC or Data Logger
When you configure level using the Sensors tab, the settings are stored in the instrument and are available for use in
Modbus, SDI-12, or 4-20 mA analog communication. A different configuration can be selected when you set up a log.
