Magnetic flowmeter for mining and water
January 2006
Flow Measurement & Control
The electromagnetic flowmeter has been a tried and trusted, maintenance-free industrial flow measurement device for many years, and now Flowmetrix SA has introduced the new generation of SAFMAG flowmeters which incorporate a multitasking microprocessor to handle all functions simultaneously.
Fluids with conductivities of 5 micro-siemens/cm and above can be accurately metered by the SAFMAG, which also offers advantages of unrestricted pipe cross-section and independence of density and fluid viscosity. The performance of the SAFMAG is unaffected by changes in process pressure, temperature and fluid conductivity.
The main feature of magnetic inductive flowmeters is that they have no moving internal parts, which guarantees no pressure loss, no restriction and no jamming of travelling particles. The flowmeters' rugged design and reliability make it most suitable for use with conductive fluids, with or without solid particles.
The new generation now includes primary sensing heads with conductive rubber electrodes, instead of steel, to sense the flow signal. This development now enables converters based on 'pulsed DC technology' to also be used on mining slurries. Correctly measuring mining slurries was up to now only possible by using converters which were based on the 'AC field technology'.
The DCMPU Converter can now be used on all applications - the pulse DC technology and continuous automatic rezeroing makes it a preferred choice. The simple and practical design of the SAFMAG enhances reliability. The flowtube housing is fully welded and pressure tested to ensure a complete seal against moisture and other contaminates. The field wiring is isolated in a separate terminal box, sealed from the coil housing to ensure that the coil housing is not contaminated by possible conduit entry infiltration. User friendly, self-explanatory input or interrogation of measurement data is done directly on the converter by means of four pushbuttons. An easily readable 2-line display is used to display flowmeter data, the configuration data being stored in nonvolatile EEPROM memory.
The SAFMAG flowmeters, which are available locally from OMSA Valves and Instrumentation, have applications in the water, sewage, paper, pulp, chemical, steel, mining, food and beverage industries.
