  • Page 14: Mounting Instructions

    Type of vessel Plastic vessel/Glass vessel The guided microwave principle requires a metallic surface on the process fitting. Therefore, in plastic vessels, etc., use an instru- ment version with flange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process fitting when screwing it in. Make sure that the plate has direct contact with the process fitting. When mounting rod or cable probes in vessels without metal walls, e.g. in plastic vessels, the measured value can be influenced by strong electromagnetic fields (emitted interference according to EN 61326: class A). In this case, use a probe with coaxial version. VEGAFLEX 83 • Modbus and Levelmaster protocol...

    General configuration of the host The data exchange with status and variables between field device and host is carried out via register. For this, a configuration in the host is required. Floating point numbers with short prevision (4 bytes) according to IEEE 754 are transmitted with individually selectable order of the data bytes (byte transmission order). This "Byte transmission order" is determined in the parameter "Format Code". Hence the RTU knows the registers of the VEGAFLEX 83 which must be contacted for the variables and status information.
