A significant percentage of flowmeters are measuring incorrectly in the food industry due to changes in consistency or throughput of ingredients, contamination or corrosion, claims Chris Ringer, UK sales manager at Krohne. Now, a new generation of electromagnetic flowmeters or 'magmeters' provides processors with accurate and comprehensive diagnostic information, thus improving reliability and measurement repeatability.
In the past, diagnostic analyses within electromagnetic flowmeters have been limited to checking the device's microcontroller or memory.
But Krohne's new Optiflux now offers a much wider range. Its three levels of built-in diagnostics provide comprehensive information, says Ringer.
"Sensor and converter diagnostics test the microprocessor, memory, and software, the temperature of the electronics, and the output," he says. "Internal checks determine whether the instrument is working to specification. This data also means that it is possible for engineers to conduct preventative maintenance rather than reacting to problems."
Ringer believes that many magmeters on the market today are inaccurate in demanding applications. Inaccuracies also result from the complexities of operating and in maintaining different measuring instruments on site -- each with their own installation and operational guidelines.
Optiflux overcomes these problems, with flow sensors for all applications, and one converter used across the whole family. "Complexities can be eliminated and costs reduced by standardising on the measurement technology used across a plant," says Ringer.
"The increased diagnostic capability of this range of electromagnetic flowmeters enables engineers to pinpoint and rectify the causes of poor quality measurement. They can also provide an advanced warning of likely problems."
