FBM207C RH917GY Thermal resistance module

Extensive diagnostics of the device and application The primary focus of a user for a flowmeter is that it delivers reliable and robust measurements. To achieve this all electromagnetic flowmeters are calibrated before leaving the factory. In addition, KROHNE was one of the first to introduce extensive diagnostic features. The IFC 300 provides a wide range diagnostic functions on the flow sensor, signal converter and process integrated in the signal converter. The IFC 300 automatically performs an online cyclical verification to determine whether the measuring device is still within its specifications regarding accuracy and linearity. Potential problems that may occur in the process including gas bubbles, solids, electrode corrosion, deposits on electrodes, conductivity changes, empty pipe, partial filling of the sensor, disrupted flow profiles. External magnetic fields can be detected by the IFC 300 diagnostics features. Diagnostic info available via local display, status outputs, Fieldbuses, Pactware or the OPTICHECK

OPTICHECK tool for on-site verification

 The OPTICHECK provides an inline health check of the device under test by an external tool. When the tool is connected on site, it gathers measuring data to ensure that the flowmeter performs within 1% of its factory calibration. The baseline can be historic repair data from the factory or on-site test results after performing a full verification. A hard copy of the verification report can be printed for every flowmeter. The verification data are digitally stored. Contact us for more information or for an on-site service visit.

Virtual reference option simplifies installation 

Based on a special method, developed by KROHNE, called virtual reference or grounding, electromagnetic flowmeters can be installed in any type of pipeline, without grounding rings or electrodes. The virtual reference option on the IFC 300 provides complete isolation of the signal converters input amplifier and coil power circuits. It is ideal for applications in the water and wastewater industry where large diameters are common or in case of abrasive or corrosive application that require rings of expensive materials. In these case the costs for grounding rings can be substantial. Virtual reference also increases safety as it decreases the number of potential leakage points. Furthermore it is no longer necessary to select the right grounding ring (material) and reduces the risk of wrong installation of grounding rings and gaskets.

Measuring principle

 An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of the fluid, a voltage U is generated: U = v * k * B * D in which: v = mean flow velocity k = factor correcting for geometry B = magnetic field strength D = inner diameter of flowmeter The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and convert it into signals for totalizing, recording and output processing.
