ENVEA - Model DensFlow -Flow Measurement Instruments for or Dense-Phase Conveying
FromENVEA
Continuous solids mass flow measurement in dense-stream conveying and high levels of throughput. Designed to measure solid flows during pneumatic dense phase transport. The sensor measures density and speed. No wear thanks to the ceramic inner pipe.

In pneumatic dense-stream conveying , the installation point is specified in accordance with the conveyed inlet and outlet paths.
The assembly of the measuring tube at the specified installation point takes place using a flange installation. Measuring tubes can be supplied in standard form in nominal widths of up to 150 mm with flange connections in accordance with DIN 2576.
