2. Function
•
SolidFlow is a measuring system especially developed for measuring the flow rate of conveyed solids in
metallic ducts.
•
The SolidFlow sensor is based on the newest microwave technology. The sensor is usable in metal
ducts. Through the coupling of the microwave in the duct it is created a homogenous measured field.
•
The microwave energy is being reflected by the solid particles and received by the sensor. These signals
are evaluated in frequency and amplitude.
•
Because of the selective frequency evaluation only moving particles are measured.
•
The measuring signal is independent of pressure and temperature in the duct. A measuring unit
consists of one sensor and the evaluation unit.
