MicroFlow
The MicroFlow sensor reliable detects pneumatic conveyed bulk and solids in horizontal and vertical metallic pipes. The sensor does not tower inside the pipe, thus mechanical wear and tear is avoided. The sensor works as a “stand-alone” –system with a programmable 20 mA output for flow rate control. It is suitable for self-assembly and can be easily calibrated.
Detection of Pneumatic Conveyed Bulk and Solids.
The sensor uses a micro wave at 24.125 GHz with less than 5mW transmitting power. It is flush mounted via a ½” screw thread at the pipe wall. At its front side it transmits a measurable frequency. From the reflected signal the mass flow rate is directly detected and is read out as an analogue signal proportional to the mass flow rate. Optionally an external controller interface can be used. It provides the evaluation and data log, data transfer via interface, e.g. Profibus. The Micro Flow is unaffected by temperature and pressure. It provides accuracy from 2% to 5% independent of installation position and flow profile of particles. In order to achieve a better accuracy – especially in case of larger pipe diameters – the interconnection with one controller can be utilized. The controller provides easy calibration as well as displaying mass flow (kg/h, t/h) and absolute quantity (kg, t), graphic display, logical switching sequences,data logger via customary USB stick, line graph and remote maintenance.
