Ultrasonic Flow Meters Product Description
|
The Global Water FM500 ultrasonic flow meters provide accurate and trouble free
flow metering for a wide range full pipe applications including: potable water,
raw wastewater, effluent, well water, slurries, or virtually any sound
conducting liquid. The FM500 ultrasonic flow meter incorporates the
latest ultrasonic technology to give you an accurate, easy to use hybrid flow
meter with selectable Doppler or transit-time operating modes. With their
quick and easy clamp-on transducer installation, factory pre-configuration and
user programmable menu driven interface, the ultrasonic flow meters are a snap
to commission in the field. The reliable FM500 ultrasonic flow meters use
custom algorithms and DSP technology to ensure high accuracy flow metering, and
the proprietary AGC (Automatic Gain Control) algorithm eliminates the need for
manual gain adjustments.
Ultrasonic Flow Meter's Great Features
Loaded with the features, the FM500 ultrasonic flow meters include: five
programmable and password protected configurations for multiple user and
portable applications, an easy to read 320 x 240 pixel backlit LCD display,
data logging to standard SD Card format (user configurable to time interval,
flow rate and total set-point triggers), isolated 4-20mA analog and 0-1000Hz
pulse outputs.
Ultrasonic Flow Meter's Optional Features
Optional features include: three configurable relay outputs and a
communications package that allows the ultrasonic flow meter to connect to your
computer via RS-232, RS-485, USB or Ethernet. The ultrasonic flow meter's
communication package also permits remote access and control of all functions
including real-time display, system configuration, data logging, remote data
capture and process control functions. The software included with the
ultrasonic flow meter's communication package allows remote internet access
through a local network set-up.
Custom Configured Ultrasonic Flow Meters
The FM500 ultrasonic flow meters can be configured for your specific pipe and
process liquid application so that it is ready to go out of the box. We
will need the following information for configuration purposes:
Pipe size (ID), material and schedule (EG: 3 inch schedule 40 PVC)
Process liquid being measured (EG: raw wastewater)
Volumetric and time units to be displayed (EG: US gallons/minute)
Language displayed (EG: English)
How The Ultrasonic Flow Meters Work
The Global Water series Hybrid Ultrasonic Flow Meters can measure fluid flow in
virtually any fluid in which sound waves can travel. The Ultrasonic Flow
Meters are considered "hybrid" because they can measure fluid flow using either
the Doppler or Transit Time methods. The Global Water ultrasonic flow
meter's sound transducers are clamped to the outside of the pipe wall and
include no moving parts. This method of flow measurement is safe,
non-intrusive and very easy to service.
The Ultrasonic Flow Meter's Doppler measurement method requires particles be
present in the flow stream to "reflect" the sound waves. The ultrasonic
flow meter may not read flow correctly when using the Doppler mode if the fluid
contains no particles. For best results 0.02% to 15% (200 to 150,00 ppm)
particles should be present in the flow stream.
The Ultrasonic Flow Meter's Transit Time measuring method requires relatively
"clean" fluid to enable the sound waves to complete their circuit. The
Ultrasonic Flow Meters may be operated in the Transit-Time mode when the fluid
contains 0% to 10% (0 to 100,000 ppm) of particles. To allow for changes
in the fluid's particle count, the Global Water Ultrasonic Flow Meters monitor the
signal gain and employ an Automatic Gain Control (AGC) algorithm that
periodically adjusts the gain to maintain the optimum power level.
The speed at which sound travels in the fluid must be known. The factory
will configure the ultrasonic flow meter for a known fluid during the initial
configuration. The Global Water Ultrasonic Flow Meters include a 5-button
user interface that can be used to configure the meter. Many common
fluids are listed in The Ultrasonic Flow Meter's software and can be selected
directly from the menu. Provided the speed of sound in the fluid is
known, custom "unknown" fluids can be input into the ultrasonic flow meters
manually by the user. A list of various fluids and their sound speeds are
provided in the ultrasonic flow meter's user manual.

Ultrasonic Flow Meters Applications
|
|
The FM500 ultrasonic flow meters are ideal for many applications including
sewage, wastewater, pulp & paper slurries, DI water, discharge water,
caustics, chemical slurries, ground water, food and beverage, petrochemical,
and any other sound conducting liquid.
