BI 7300 Stack Flowmeter is used for continuous measurement of Velocity in stack using Multiport Pitot Tube. It is based of differential pressure – flow measurement principle and compensated for pressure and temperature. In addition to velocity; temperature, static pressure and flow rate of emission gases can also be measured.

Stack Flowmeter comprises of pitot tube, differential pressure transmitter, absolute pressure sensor, temperature sensor, control unit for computation of velocity and gas flow rate & Auto Purge unit.

The Stack Flow meter features fully automatic purge system for high dust concentrations in stack. The system purges the pitot tube automatically and periodically at regular intervals in order to avoid blockages even with large dust and particle loads to guarantee maintenance free continuous operations.
