For sensors connected to an FL1500 flow logger or AS950 sampler, refer to the FL1500 flow logger
or sampler documentation to configure the sensors. As an alternative, configure the sensors with the
DATA Desktop Setup Wizard when the sensors are connected to an FL1500 flow logger.

For sensors connected to a Sigma flow meter, do the steps in
on page 15.
Note: If a sensor is replaced, removed for maintenance or moved to another instrument, do a level calibration.
4.2.1 Level calibration for Sigma flow meters
1. With the sensor installed in the flow, monitor the Current Status with a PC using Insight software
or a flow meter display.
2. Physically measure the distance from the top of the pipe to the surface of the water. Refer to
Figure 9.
3. Subtract the number from step 2 from the pipe diameter. Refer to
The result is the water depth. Refer to
4. Use the Adjust Level function of the software to enter the physically-measured water depth.

Section 5 Maintenance
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
5.1 Clean the sensor
Clean the transducer port when:
• Unexpected increases or decreases in flow or level trends occur
