Ideal for municipalwithoutstormwater, combined effluent, raw sewage and irrigation AVFM uses a submerged ultrasonic sensor to continuouslymeasure both Velocity and Level in the channel. The sensorresists fouling corrosion. The flowmeter can be,and abrasionconfigured with the standard submerged velocity-level sensor, orwith submerged velocity plus a separate non-contacting ultrasoniclevel flowrate and total flow on the large backlit LCD display andconnect to external devices with three 4-20mA outputs and twocontrol Velocity + Level to Monitor Flowwith an Ultrasonic SensorEasy to UseThe AVFM Area-Velocity FlowMeter measures bothandLevelVelocity to calculate flow in an openchannel or pipe. Calibration is simple:enter the pipe diameter or channeldimensions and the AVFM computes and displaysflow ultrasonic sensor mounts inside the pipe orthe bottom of a channelonwith a stainless steel mountingbracket (included) and a single screw into the bottom of the pipe or channel. No special compounds, tools orhardware are required. The sensor is completely sealed withorifices or ConditionsPipe orCareful selection of sensor mounting location results in best performance and maintenance-free operation. Avoid locationswhere sediment builds possible accuracy will result when tis notand where velocity is evenly distributed across thehe waterhighly or directionThe channel should not havechanges immediately upstream of the sensor mounting or channel slope should not exceed 3%.The AVFM can measure forward flow velocity up to 20 ft/sec (6 m/sec) and reverse flow up to 5 ft/sec ( m/sec).

Theflow rates continuouslystablesubmergedvelocity/leve l sensor will measure flow in partially full and surcharged pipes with pressure up to 10 psi. No special set-upor adjustment is required. Minimum recommended pipe diameter is 6 (150 mm).Alternate Sensor ConfigurationsThe standard sensor measures both velocity and level with a singlesubmerged probe. It is installedthe pipe or channel floor withinthestainless steel mounting bracket (supplied), or mounted with anoptional stainless steel band for round pipes modelsare available for special applications: a separate non-contactingultrasonic level sensor with a submerged velocity sensor can be extended up to 500 ft (150 m).Custom Channel ShapesCalibrate the AVFM for installation in irregular or compound channel shapesby entering the channel width at multiple level points through a simple of virtually any shape can e monitored with your choice ofbmeasurement 2-Million Point Data LoggerChoose the built-in data logger option if you want the AVFM to store time and date-stamped flow values at 10 second to 60 minute intervals. Daily flow reports areautomatically created where total, minimum, maximum and average flow rates aredisplayed on the LCD display. Transfer log files to any USB flash drive just by connectingto the logger's USB output. Windows software is included to display log files in graph andtable formats, change measurement units and generate flow reports.
