Dust & Flow Monitor

In-situ instruments that measure dust concentration and flue gas flow directly inside the stack.

Application: Air Emission Monitoring
Sector: Biomass, Carbon black, Cement, Foundries, Iron & steel, Power generation (PLN, coal-fired)
Specifications: Configured for site conditions. Datasheet available on request.

Pair of dust and flow monitor heads with a purge air blower

Operational use cases

Particulate monitoring on boiler, kiln, and furnace stacks.
Flow rate for calculating emission loads.
Complementing gas CEMS within one monitoring system.

Measurement principle

The sensors are mounted on the stack wall and read conditions inside the gas stream directly, without extracting a sample. Purge air keeps the optics and sensors clean.

The measurement method is selected for the dust load, stack diameter, and flue gas conditions at your site.

Working principle: In-situ dust and flow measurement
