Description
Flow measurement using Ultrasonic
Doppler technology is accepted as a reliable, non-invasive
method of measuring liquid and slurry flow in pipes, where high
accuracy is simply not required.
The Pulsarflow 500
series utilises this technique to provide cost effective flow
monitoring and switch point output.
There are three units in the
range, Pulsarflow 510, a general purpose system and
Pulsarflow 511 for use in flammable atmospheres
(available in 2002), and the Pulsarflow 515 high
velocity unit up to 6m/sec.
Application
The Pulsarflow 500
series is capable of operating in general purpose flow switching
and measurement applications with velocities from 0.3 m/sec to
3.5 m/sec ( a high velocity version the 515 up to 6m/sec is
available) for liquids and slurries.
Operation
Pulsarflow 500 series
unique design combines both sensor and electronics in a single
stainless steel enclosure which allows quick and easy
installation on the outside of a metal or plastic pipe. Pulsarflow
500 series has internal transmit and receive transducers which
detect ultrasonic reflections from particles or air inclusions
in the liquid or slurry. The change in frequency detected from
these reflections is proportional to the velocity of the
particle in the flow, and therefore can be converted by the
system into a flow indication. It is possible, on the majority
of liquids, to indicate the flow rate and provide a repeatable
switching point on higher or lower than desired flow.
Each unit has ease of
installation and calibration as a key feature, having a single
button set up with a status feed-back during initial calibration
from red and green LEDs. The Pulsarflow 500 series has
ingress protection to IP68. The rugged stainless steel unit
provides a high degree of protection from bump, shock and
vibration within a typical industrial environment.
