Electromagnetic Flow meter
Electromagnetic Flow meter


The food industry due to product hygiene and sanitary requirements, the need to disinfect the process pipe regularly with disinfectant media, the media used are hot water, steam, caustic soda and hydrogen peroxide. In this regard, we need to pay attention to the use of the above medium with a higher temperature sterilization process, which is with the electromagnetic flow meter lined with a certain risk, if the operation is a little careless, easy to damage the instrument.

From the anti-corrosion, temperature and health point of view, the electromagnetic flowmeter lining material selection of PTFE or PFA for the majority of food industry users. In actual use, the air in the process piping expands due to the higher temperature medium and prolonged flushing, while the PTFE/PFA lining softens. If at this time installed flowmeter valve on both ends of the pipeline by mistake, the pipe temperature drops over time, the tube air or liquid also will produce a negative pressure to damage the lining. Electromagnetic flowmeter lining on negative pressure bearing capacity and process parameters, and the lining material characteristics vary.
