Using virtual reference grounding for electromagnetic flowmeters

Electromagnetic flowmeters (EMFs) are the leading choice for recording the volume flow of electrically conductive liquids in a wide range of industries, including chemical, pharmaceutical, water/wastewater and food. Like all electrical equipment, EMFs must be grounded for safety reasons. Grounding is usually done by using the conductive non-lined pipe flange, grounding rings, or occasionally with grounding electrodes.
