Installation for Flo-Dar or Flo-Tote sensors
Install the air reference tube and external desiccant to make sure that the pressure transducer in the
sensor operates correctly. The desiccant cartridge prevents damage from moisture and debris.
Moisture and debris can decrease the accuracy of the Flo-Dar and Flo-Tote sensors.
If the instrument is installed in a high-moisture environment, install a desiccant cartridge.
1. Remove the plug from one of the air reference ports. Refer to
Note: Do not remove the plugs from the air reference ports that are not used.
2. Push the air reference tube from the sensor into the air reference port.
Note: If the sensor cable is pulled through a conduit, protect the wiring and air tube from damage and
contamination.
3. Install an external desiccant cartridge on the air inlet port. Refer to
on page 30.
