    AVFM 6.1 INSTRUCTION MANUAL CALIBRATION Range Only shown when the level sensor used is a through-air PZ type. Max range should be set as the distance from the face of the PZ sensor to the zero level reference point of the pipe/channel it is installed above. See drawing below.
  • Page 15 PULSAR MEASUREMENT CALIBRATION (cont.) Level For QZ02L (submersible, default) level sensor, set the maximum height the level should reach in the system, in units configured in the Units/Mode menu. If a Round pipe is selected in the Channel Setup menu, then this value should be set to the same value as the inside diameter.

    Press  or  to select the logging interval. Press  to Interval store the setting. Pulsar Measurement recommends choosing an interval which will give you as much resolution as required and no more. Choosing too often of an interval for what is required will result in larger data files, which may take a long time to download to USB.
  • Page 23 Press  to return to the main display. RETRIEVING LOG FILE Plug a USB Flash Memory Drive (one is included with the AVFM 6.1) into the USB output port on the Panel of the meter. The instrument display will show the data download icon until the log file is transferred to the memory card.
  • Page 24 Install Greyline Logger on your PC or laptop. Select File/Open/Instrument Log (.log) to open the log file from your USB flash drive.

  • Page 28: Installation - Sensor Location

    AVFM 6.1 INSTRUCTION MANUAL INSTALLATION – SENSOR LOCATION For the most accurate flow measurement possible, careful consideration should be made to the placement of the sensor in relation to flow disturbances. In general, the best accuracy will occur where flow is evenly distributed across the channel/pipe and free of turbulence.
  • Page 29 FLOW Hydraulic Dams When the QZ02 sensor is to be mounted in front (upstream) of a hydraulic dam, or a Pulsar Measurement VD pipe dam, the sensor should be placed at least 20 inches in front of the dam: Pipe Grade...
  • Page 30 AVFM 6.1 INSTRUCTION MANUAL Flow Profile Distortion The pipe/channel in which the QZ02 sensor is mounted should be free of bends, tees, sudden changes in slope, and there should not be objects in the pipe/channel which disturb the flow profile in front of the sensor.

Ensure that the sensor bracket is parallel to the water surface (check with a level). Mount so the tapered end of the sensor will point upstream and the sensor cable will point downstream.
  • Page 34 AVFM 6.1 INSTRUCTION MANUAL OPTIONAL PZ15-LP LEVEL SENSOR MOUNTING Mount the PZ15-LP non-contacting ultrasonic level sensor in an unobstructed position at least 8” (203.2 mm) above the high water level. Install the stainless steel mounting bracket in a horizontal position (check with a level) and then insert the PZ15-LP sensor.

  • Page 35: Enclosure Installation

    Locate the enclosure within 20 ft (6 m) of the sensor (up to 500 ft -150 m optional). The enclosure can be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel Mount kit from Pulsar Measurement.

  • Page 36: Field Troubleshooting

    AVFM 6.1 INSTRUCTION MANUAL FIELD TROUBLESHOOTING The AVFM 6.1 uses an ultrasonic level sensor to determine flow area and an ultrasonic Doppler sensor to measure flow velocity. The QZ02L sensor combines both sensors in one housing. An optional configuration uses the PZ15-LP “down-looking” level sensor and a QZ02L-B velocity sensor.
  • Page 37 PULSAR MEASUREMENT SENSOR CABLE RESISTANCE TEST Unplug the 4-pin green sensor terminal from the Doppler board and connect the sensor wires as shown. With a multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false readings.
