1 System Overview
Overview of the measuring system
2 Function
•
DensFlow is a measuring system especially developed for measuring the flow rate of
conveyed solids in densephase.
•
DensFlow is working according to the latest microprocessor technology. By special
capacitive linking of an electromagnetic wave a homogeneous measuring field is
produced in the pipe.
•
The electromagnetic wave brought into the pipe is reciprocally acting with the solid
particles. These signals are evaluated in frequency and amplitude.
•
The measurement of the solid speed is done by means of correlation. Two capacitive
sensors are used for the production of the correlation signals.
•
A complete measuring unit consists of the sensor (measuring pipe) and the
evaluation unit.
