The Doppler velocity sensor gathers peak flow velocity data.
These sensors display exceptional durability and accuracy, even
under harsh and turbulent flow monitoring conditions.
The monitor receives the raw data from the sensors based on a
defined time interval and then processes the data, which may
involve calculating the flow rate. This data, stored in the monitor
memory, is available to the user for collection, further processing,
analysis, and reporting. The reports can assist municipalities and
other industry in planning improvements and additions to sewer
systems, improving the accuracy of billing information, and
providing information for the overall management of sewer
systems.
Special software called FieldScan  enables the user to configure
and communicate with the monitor for activation, data collection,
confirmation, and diagnostic purposes. Configuration involves
defining the location information file (LIF) for storage in the user's
local directory and building the BASIC code and variables for the
site. The LIF contains information such as pipe characteristics,
monitor identification, selected devices, sensor offsets, data log
rate, and other parameters necessary for measuring the flow both
accurately and efficiently.
Note: Refer to the FieldScan User's Guide (#950021**)
for more information.
Activation involves downloading the BASIC code and site-specific
information from the LIF (stored in the user's local directory or
network drive) to the monitor. It also includes initiating monitor
activities such as taking sensor readings, logging flow data,
recording pulses from a rain gauge, sending signals to a sampler,
and managing event notification.
Communication between the monitor and the user’s office or field
computer can occur over a telephone line (remote communication),
cellular digital packet data (CDPD) device (wireless
communication), or direct modem interface (DMI) cable (on-site
communication).
A 4000 monitor specially equipped to receive power from an
external DC power source is available by special order. A
