  • Page 3: System Overview

    Sensor (Measuring Pipe) Evaluation Unit 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.

  • Page 4: Safety

    3 Safety • The measuring system DensFlow was designed, built and tested to be safe and was shipped in safe condition. Nevertheless persons or objects may be endangered by components of the system if these are operated in an inexpert manner. Therefore the operational instructions must be read completely and the safety notes must be followed.

    The correct cabling between sensor and the evaluation unit. • The correct adjustment of the sensor pipe. Commissioning DensFlow For start-up the sensor has to be calibrated and parameterized to each product, which will be measured. It is necessary to assign the mass flow to the display and initial value.

  • Page 16: Maintenance

    In case of a defect during the warranty period, defective components are repaired or are replaced free of charge. Replaced parts turn into the property of SWR. If desired by the customer that the parts should be repaired or replaced in its factory, then the customer has to take over the costs for the SWR-service staff.
