PCM Sensor for 2" pipe
Electronics Unit
Clamp-on
Process Sensing
The PCM-100 will operate on any homogeneous liquid that will
carry a sound wave. The presence
of small amounts of gas bubbles is adjusted for by the monitor. Due
to the non-intrusive, clamp-on design, the monitor cannot be fouled by the
process fluids. In addition, it
can be installed and
moved without interfering with normal operations. Calibration of the PCM-100
is based on
samples of the process liquid. Up to ten calibrations can be stored to allow
operation
with various process formulations.

Principle
of operation
| A pair of sonic transducers are clamped on opposite sides of
the process pipe. High
frequency sonic waves are sent out by one transducer, pass through the
pipe walls and fluid, and are sensed by the other transducer.
High-speed processing of the sonic signal is used to calculate the
component concentration. The concentration is displayed on the terminal
and output as a 4-20 milliamp signal. |

Applications
The clamp-on monitor can be used on any process where fluid composition needs to be
measured for for quality
assurance. It is applied to process applications where samples are currently being analyzed
and operations would benefit from reduced sampling and/or continuous
measurements. Applications requiring sensitive composition
monitoring include:Examples
 |
|
 |
•Monitor
effluents from industrial plants
|
 |
•Control
quality of chemical products
|
 |
•Measure
solids concentration on-line
|
 |
•Monitor
reactions in real time (polymerization)
