1.General Description
Continuous Indicative Particulate Monitoring
With the recent increase in world-wide environmental legislation, there has evolved a general
requirement for operators to monitor the performance of their dust collectors and ensure that
emissions to atmosphere are kept below the maximum legal enforcement level.
In the case of small collectors or non-critical processes, it has been accepted by legislators in the UK,
that low cost continuous indicative particulate monitors may be used. These devices give an output
that shows the operator a relative increase or decrease in dust loading and have the facility to initiate
alarms if an unacceptable level is exceeded. Such instruments are described as ‘indicative’ and are
not intended to give quantitative results. They are normally set up using subjective criteria and
without reference to a standard gravimetric stack test.
The better indicative monitors, such as Energy Tech 301, have an analogue and RS485 output that
can be used to constantly record the output from the instrument and enable the operator to review the
results and identify impending filter failure at an early stage. The results may also be used to show
evidence of good practice to environmental authorities.
Whilst it is not recommended to calibrate this class of instrument in mg/m3, the operator may wish to
set an alarm point with reference to a specific mass concentration of particulate required by law. This
manual will show a method that satisfies this requirement using a single iso-kinetic stack test.
If emissions are required to be quantified in mg/m3 on a continuous basis, then please contact Codel
for advice.
