Flow sensors and transmitters are offered
based upon the customer's flow conditions, temperature, pipe size, fluid
characteristics and other factors.
Non-contact flow meters clamp onto
the outside of a pipe and use either Doppler or Transit Time
technology to measure and transmit flow rates. Data logging is also
possible. This technology can be used on any pipe size and material.
With a choice of technologies no application is too difficult. The
transmitters from Blue-White Sonic-Pro are finally here! Call us for
more details. We can even send you a video explaining more.
Gravity flow is best monitored with an
ultrasonic level transmitter coupled with a flume tailored to the expected flow
rate. For most applications a Palmer-Bowlus flume (shown in cross section
above) is used. Common applications require a chart recorder to show the
flow rate and totalize the flow. The totals can be actually printed on the
chart along with the tracing of the flow rate over time. We also can supply a
digital display meter showing flow rate, totalized flow. The meter can
also output an analog signal for a recorder and a pulse output for a sample
collection unit.
Palmer Bowlus Flumes: The Palmer Bowlus metering flume has been
widely used since 1937 for measuring water and wastewater in open channels or
pipelines that are not under pressure. Some of its most important
characteristics include measurement accuracy, low head loss, minimum flow
restriction and ease of installation in pipelines.
Pressurized pipes can also be measured with turbine
or paddlewheel sensors providing the velocity exceeded a minimum criteria and
the properties of the fluid are compatible with the sensor. Of course
these limitations do not apply for the Sonic-Pro.
