Area-Velocity Flow Meter for Open Channels and Pipes
No Flume or Weir Required
Model AVFM 5.0 Display,Transmit and Totalize Flow in Open Channels
and Pipes.
- Simple 5-key Calibration
-Three 4-20mA Outputs
-Two Control Relays
- Measures Reverse Flow
-Works in Irregular Channel Shapes
Monitor flow through open channels, partially full sewer pipes and sur-
charged pipes without a flume or weir Ideal for municipal stormwater,
combined effluent, raw sewage and irrigation water
Submersible Ultrasonic Sensor
The Riels AVFM 5.0 uses a submerged ultrasonic sensor to continuously
measure both Velocity and Level in the channel.The sensor resists fouling,
corrosion and abrasion.The flowmeter can be configured with the stan-
dard submerged velocity-level sensor; or with submerged velocity plus a
separate non-contacting ultrasonic level sensor
View flowrate and total flow on the large back it LCD display and connect
to external devices with three 4-20mA outputs and two control relays.

to Monitor Flow
with an Ultrasonic Sensor
Ultrasonic Flow Monitor for Partially Filled Pipes & Open Channels
Easy to Use
The AVFM 5.0 Area-Velocity Flow Meter measures both Level andVeloci-
tyto calculate flow in an open channel or pipe. Calibration is simple: enter
the pipe diameter or channel dimensions and the AVFM 5.0 automatically
computes and displays flow volume.
The ultrasonic sensor mounts inside the pipe or on the bottom of a chan-
nel with a stainless steel mounting bracket (included) and a single screw
into the bottom of the pipe or channel. No special compounds, tools or
hardware are required.
The sensor is completely sealed with no orifices or ports.
Submerged Sensor Measures Level And Velocity
Recommended Pipe or Channel Conditions
Careful selection of sensor mounting location results in best performance and maintenance-free operation. Avoid locations where sediment builds up.
Best possible accuracy will result when the water is not highly turbulent and where velocity is evenly distributed across the channel.The channel should
not have drops or direction changes immediately upstream of the sensor mounting location. Pipe or channel slope should not exceed 3%.
The AVFM 5.0 can measure forward flow velocity up to 20 ft/sec (6 m/sec) and reverse flow up to 5 ft/sec (1.5 m/sec).The electronics and software
sample and average flow rates continuously to provide stable readings.
The submerged velocity/level sensor will measure flow in partially full and surcharged pipes with pressure up to 10 psi. No special set-up or adjustment
is required. Minimum recommended pipe diameter is 6" (I 50 mm).
Alternate Sensor Configurations
The standard sensor measures both velocity and level with a single
submerged probe. It is installed in the pipe or channel floor with the
stainless steel mounting bracket (supplied), or mounted with an optional
stainless steel band for round pipes. Alternate sensor models are available
for special applications: a separate non-contacting ultrasonic level sensor
with a submerged velocity sensor Sensor cable can be extended up to
500 ft (I 50 m).
