Manas developed electromagnetic sroat-1000 is a near ideal flow meter suitable for wide range of liquid flow mesurements even with very low conductivites. It provides no resistance to flow hence the pressure drop is almost negligible. The measurement being based on faraday`s law of electromagnetic induction is independent of viscosity density, pressure and temprature of flowing medium. This is not solid impurities as long as the mm conductivity of 5 ps/cm is available. It this is the volumetric flow measurement differnt of construction for meter lining and electrodes are available optionally to cover majority of corrosive liquids. The technique is called as pulsed dc is used which offers very high zero stability and accuracy of measurement. The dard current output of 4-20 ma dc is given which is linearly proportional to volumetric flow rate and additional frequency output is also provided. Its advantages are excellent long term zero stability; measurement independent of velocity profile across the diameter of the pipe-line; measurement results independent of density, viscosity, pressure, temperature, solid-impurities and conductivity variations [above 5th siemens] and to additional pressure drop across the meter which relieves the process designer while sizing his pumpling requirements.
