Attach The Sensor To The Mounting Band - Hach AV9000 Manual Del Usuario

Zero level calibration (Sigma 910 to 950 flow meters)
Do a zero level calibration as follows:
Note: If the sensor is replaced, removed for maintenance or moved to another instrument, do a zero level
calibration again.
1. Connect the flow meter to a computer with InSight software. Refer to the flow meter
documentation for instructions.
2. Start the InSight software on the computer.
3. Select Remote Programming.
4. From the Real Time Operations list, select the level sensor.
5. Remove the probe from the liquid and place the sensor flat on the tabletop or floor with the
sensor (the plate with holes) face down.
6. Push OK on the dialog box when complete.

Attach the sensor to the mounting band

Mounting bands have pre-drilled holes for direct mounting of the sensor to the band. Refer to the
steps and the figures to mount the sensor on the mounting band.
Note: If the sensor is the oil-filled type, make sure the sensor is filled with oil before mounting the sensor to the
mounting band. Refer to the Fill sensor oil section of this manual.
1. Attach the sensor to the spring ring
extends past the edge of the ring.
2. Route the cable along the edge of the band
3. Use nylon-wire ties to fasten the cable to the mounting band.
The cable should exit the tied area at or near the top of the pipe.
Note: If a large amount of silt exists in the bottom of the pipe, rotate the band until the sensor is out of the silt
(Figure 8 on page 14). Make sure the sensor remains below the minimum expected water level at all times.
Silt must be measured frequently but not disturbed.
(Figure 6). Mount the sensor so that the pressure transducer
