Hygienically clean electromagnetic liquid flow velocity meters for food, drink and pharmaceutical processes.
Hygienic measurement instrumentation are designed for use by the food, drink and pharmaceutical industries, which require a high level of cleanliness in their manufacturing processes.
To maintain hygiene in production processes, equipment needs to be designed so that it is possible to easily clean all parts in contact with the process media. Also the contact surface of these parts should deter the build up of bacteria and mould and other pathogens that may cause harm to human health.
Hygienic instruments have highly polished stainless steel parts exposed to the process media and are installed using clamped seals.
Direct threaded type fittings are avoided since they introduce crevices which would attract the build up of process material over time and require dismantling for cleaning. Threads are used in some types of clamped fittings in order to pull two components together to make a seal, but are only used on the non-contacting external surfaces.
Magnetic flow meters are used to measure the flow velocity of conductive fluids in a pipe. There are no moving parts in contact with the fluid making it possible to measure fluids which contain solids.
The internal surface of a magflow meter exposed to the fluid flow, which is called a liner, can be made from different materials. This makes it possible to use a magnetic flowmeter to measure corrosive chemicals by selecting a compatible liner material.
In a similar way to an electromagnetic generator, the magnetic flow meter works by the same operating principle. The conductive fluid passing through the flowmeter is analogous to the copper wire. The magnets and electrodes are fitted behind the liner, and the resulting voltage generated provides the sensor signal instead of being used to provide electrical power.
Since Magnetic flow meters have a smooth crevice free surface and no moving parts exposed to the process fluid, they are often used in food processing plants, breweries, wastewater treatment works, chemical process plants, water treatment works, pulp & paper mills and pharmaceutical plants.
