Description

Area-Velocity Flowmeter

Monitor ow through open channels, par­tially full pipes and surcharge pipes, ume
or wier. Ideal for municipal stormwater,
combined efuent, raw sewage and irriga­tion water.

Streamlined Sensor

The AVFM 5.0 uses a submerged ultrason­ic sensor to measure both velocity and lev­el. The sensor resists fouling, corrosion and
abrasion and is tolerant of turbulence and
high approach velocity. It can be congured
with the standard submerged sensor, or
with submerged velocity plus a non-contacting
ultrasonic level sensor.

View ow rate and total ow on the large back­lit LCD display and connect to external devices
with three 4-20mA outputs and two control re­lays.

Easy to Use

The AVFM 5.0 Area-Velocity Flow Meter mea­sures both Level and Velocity to calculate ow
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 ow
volume.

The ultrasonic sensor mounts inside the pipe
or at the bottom of a channel. No special com­pounds, tools or hardware are required. The
ultrasonic se sor is completely sealed with no
orices or ports.

Recommended Pipe or Channel
Conditions

Careful selection of sensor mounting location
results in best performance and maintenance­free 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 ow veloc­ity up to 20 ft/sec (6 m/sec) and reverse ow up
to 5 ft/sec (1.5 m/sec). The electronics and soft­ware sample and average ow rates continuous­ly to provide stable readings. The submerged ve­locity/level sensor will measure ow 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 Congurations

The standard sensor measures both velocity
and level with a single submerged probe. It is in­stalled in the pipe or channel oor 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 (150 m).

Three 4-20 mA Outputs

Transmit to external loggers, controllers or re­mote displays. 4-20 mA outputs are congured
to transmit level, velocity and ow. Outputs can
be turned off for reduced power consumption
(2.9 Watts minimum) or menu-congured 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 irregu­lar or compound channel shapes by entering the
channel width at multiple level points through a
. Channels of virtually any shape can be moni­tored 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 ow values at
10 second to 60 minute intervals. Transfer log
les to any USB ash drive just by connecting
to the logger’s USB output. Windows software
is included to display log les in graph and table
formats, change measurement units and gener­ate ow reports. Export data to Excel.
