Ideally designed for stack emission monitoring Model PEM-SMS-4 Stack Monitoring System is an highly advanced automatic iso-kinetic sampler, which facilitates the measurement of Particulate Matter (PM) moisture and gaseous pollutants in stacks and ducts.   It not only measures stack gas velocity but also continuously computes and regulates the sampling flow rate automatically to comply with iso-kinetic sampling conditions through out the sampling.

 PEM-SMS-4 implements the various basic methodologies developed by US EPA for measurement of Stack Gas Velocity, Moisture content and for iso-kinetic sampling of PM. Stack gas velocity computation is carried out based on the of pitot tube dp, flue gas temperature and gas composition and barometric pressure. While the pitot tube dp and flue gas temperature are retrieved from on-line measurement, gas composition and moisture contents are input manually through the key-board and display, serving as man-machine interface. The system recommends the ideal nozzle size, number of traverse points & their distances. It then computes the iso-kinetic set point, which is displayed and utilized for continuous control of the sampling flow rate through a proportional control valve. PEM-SMS-4 is programmable to select the required mode of sampling for particulate, moisture or gaseous sampling. The system provides for constant flow mode for particulates for use in cyclones.
 Solid state pressure sensors are used for measurement of Pitot Tube dp, orifice dp and inlet pressure. Temperature sensors measure stack gas temperature, condenser temperature and orifice gas temperature.
 The system is so versatile and user friendly that at no time one needs paper, pen or calculator on the field or off the field and all the data is stored in the memory.  After entering the initial & final weight of the filter paper through the keys, the system computes & printsout the particulate matter concentration, volumetric discharge & emission rate of PM from the stack.
