  • Page 24: Installation - Sensor Location

    AVFM 6.1 Area-Velocity Flow Meter 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 25 AVFM 6.1 Area-Velocity Flow Meter 2. Hydraulic Dams When the QZ02 sensor is to be mounted in front (upstream) of a hydraulic dam, or a Greyline VD pipe dam, the sensor should be placed at least 20 inches in front of the dam: 3.
  • Page 26 AVFM 6.1 Area-Velocity Flow Meter 1. 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.
  • Page 27 AVFM 6.1 Area-Velocity Flow Meter QZ02L VELOCITY-LEVEL SENSOR MOUNTING Mount the QZ02L sensor with the stainless steel bracket and hardware supplied. Ensure that the sensor is parallel to the water surface (check with a level). Mount with the tapered end of the sensor pointing upstream and the sensor cable pointing downstream.

  • Page 29 AVFM 6.1 Area-Velocity Flow Meter OPTIONAL PIPE BAND MOUNTING WITH QZ02L SENSOR Install the stainless steel pipe band with the sensor mounting bracket at the invert (bottom) of the pipe. Ensure that the sensor bracket is parallel to the water surface (check with a level).
  • Page 30 AVFM 6.1 Area-Velocity Flow Meter 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 31: Enclosure Installation

    AVFM 6.1 Area-Velocity Flow Meter 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 Greyline Instruments.

  • Page 32: Field Troubleshooting

    AVFM 6.1 Area-Velocity Flow Meter 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 33 AVFM 6.1 Area-Velocity Flow Meter 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.
