Flow velocity to determine flow rate
Exhaust air of the chamber dryer
Depending on the chimney’s diameter. For example in DN 1,100 mm from 10,000 – 90,000 m³/h
Atmospheric, slight over or underpressure
Dusty, temperatures from 110 °C up to 180 °C max.
Safe, fast exhaust air flow rate measurement under all water saturation conditions, even with dust load and condensate.
The measurement is part of the dryer regulation which helps save a lot of energy.
Easy transfer of measuring data through the analog 4-20 mA signal and counting pulse. Very robust measuring method. Energetically viewing and optimising the drying process to save energy and reduce errors in drying by measuring flow rate of exhaust air.
This sensor with no moving parts allows measurements in dusty and condensate-laden brickworks exhaust air, within a wide measuring range from 0.5 – 40 m/s. Additional piston ring sealing is possible in case of strong condensation.
Design for all ATEX zones up to 180 °C with SIL2 or SIL3 certificate possible
Brick drying happens in drying chambers that are fed with pallet trucks. The goal is to reduce any residual moisture to optimise the following burning process.
The drying process is often „regulated“ through simple temperature measurement and experience. To optimise this energy-intensive process the exhaust air‘s flow rate in combination with its water content need to be measured. This data is the foundation for process control. The bricks are being dried in the drying chamber until the desired residual moisture is achieved. The result of the brick factory‘s exhaust air measurement: an optimised use of energy while assuring quality. A measurement that pays off!
