Aquametrix AVFM-5 Area Velocity Flow & Level Monitor - Manual

Area-Velocity Flowmeter
Monitor flow through open channels, par-
tially full pipes and surcharge pipes, flume
or wier. Ideal for municipal stormwater,
combined effluent, raw sewage and irriga-
tion water.
Streamlined Sensor
The AVFM 5.0 uses a submerged ultrason-
ic sensor to measure both velocity and lev-
el. The sensor resists fouling, corrosion and
abrasion and is tolerant of turbulence and
high approach velocity. It can be configured
with the standard submerged sensor, or
with submerged velocity plus a non-contacting
ultrasonic level sensor.
View flow rate and total flow on the large back-
lit LCD display and connect to external devices
with three 4-20mA outputs and two control re-
lays.
Easy to Use
The AVFM 5.0 Area-Velocity Flow Meter mea-
sures both Level and Velocity to calculate flow
volume in an open channel or pipe. Calibration is
simple: Enter the pipe ID or channel dimensions
and the AVFM 5.0 computes and displays flow
volume.
The ultrasonic sensor mounts inside the pipe
or at the bottom of a channel. No special com-
pounds, tools or hardware are required. The
ultrasonic se sor is completely sealed with no
orifices or ports.
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 veloc-
ity 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 veloc-
ity up to 20 ft/sec (6 m/sec) and reverse flow up
to 5 ft/sec (1.5 m/sec). The electronics and soft-
ware sample and average flow rates continuous-
ly to provide stable readings. The submerged ve-
locity/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” (150
mm).
Alternate Sensor Configurations
The standard sensor measures both velocity
and level with a single submerged probe. It is in-
stalled in the pipe or channel floor with the stain-
less steel mounting bracket (supplied), or mount-
ed 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 veloc-
ity sensor. Sensor cable can be extended up to
500 ft (150 m).
Three 4-20 mA Outputs
Transmit to external loggers, controllers or re-
mote displays. 4-20 mA outputs are configured
to transmit level, velocity and flow. Outputs can
be turned off for reduced power consumption
(2.9 Watts minimum) or menu-configured with
0-5 VDC outputs for power consumption as low
as 3.6 Watts.
Custom Channel Shapes
Calibrate the AVFM 5.0 for installation in irregu-
lar or compound channel shapes by entering the
channel width at multiple level points through a
. Channels of virtually any shape can be moni-
tored with your choice of measurement units.
Optional 2 Million point Data Logger
Choose the built-in data logger option if you want
to store time and date-stamped flow values at
10 second to 60 minute intervals. Transfer log
files to any USB flash drive just by connecting
to the logger’s USB output. Windows software
is included to display log files in graph and table
formats, change measurement units and gener-
ate flow reports. Export data to Excel.
