Info

• Do not use sites with low-velocity flows that create silt buildup in the invert or channel. Buildup of silt near the sensor can inhibit the Doppler signal and cause inaccurate sensor readings and depth measurements. • Do not use sites with deep rapid flows where sensor installation would be difficult or dangerous. • Do not use sites with high-velocity, low-depth flows. Splash-over and excessive turbulence around the sensor can cause inaccurate data. Strain relief for sensor cable Attach the desiccant hub to the instrument to give strain relief to the sensor cable and the cable connector. Refer to the figures for proper attachment. Figure 3 Proper strain relief Zero the sensor The sensor is calibrated at the factory and is compensated for temperature. The sensor must be zeroed during each installation and when moved from one flow meter or sampler to another. Zero the sensor for FL900 series flow meters To zero the sensor when used with FL900 series flow meters, open the Flo-Ware software. Follow the instructions in the Calibration Wizard for the AV9000 Area Velocity Analyzer Sensor. Zero the sensor for Sigma samplers and flow meters 1. If necessary, install the InSight software, version 5.7 or higher, and start the program. Note: Insight software can be downloaded from http://www.hachflow.com (search for InSight), or ordered on a compact disc from customer support. 2. From the InSight menu, select Remote Programming. 3. From the Real Time Operations list, select the level sensor. 4. 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. 5. Press OK on the dialog box when complete. Note: The AV9000 analyzer includes a sensitive radio-frequency receiver capable of detecting very small signals. When connected to the FL90x logger communications or auxiliary power ports, certain line-powered equipment may inject noise that interferes with Doppler velocity measurements. Interference with 8 English
measurements is uncommon in typical sites. The AV9000 is most sensitive to noise falling within its Doppler analysis span of 1 MHz ±13.3 kHz. Noise at other frequencies is typically benign. Some laptop computers have caused interference problems when operated from external AC power adapters. If such a device is affecting your measurements, try running it from batteries, or disconnect the cable between it and the FL90x logger. 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 (Figure 4). Mount the sensor so that the pressure transducer extends past the edge of the ring. 2. Route the cable along the edge of the band (Figure 4). 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 6 on page 11). Make sure the sensor remains below the minimum expected water level at all times. Silt must be measured frequently but not disturbed.
