We are Manufacturer, Supplier, Exporter of Magmeter Sroat, Flowmeters. Our setup is situated in Pune, Maharashtra, India and majorly we serve our customers from Australia, New Zealand and India.

Introduction :
The Manas make Electromagnetic Flow meter called as Sroat 1000 virtually approaches the ideal flow meter suitable for wide range of liquid flow measurement even with very low velocities and conductivities. Some of the industrial applications include: Effluent treatment plants, Sewage treatment plant, Water supply schemes, Steel industry, Sugar industry and distillery, Pulp and paper, Chemical and pharmaceutical, Food and Drug industry.

The meter offers 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 visocity, density, pressure & temperature of flowing medium. The measurement is not affected by solid impurities as long as the min. conductivity of 5µs/cm is available.

It is a true volumetric flow measurement.We offer various materials of construction for meter lining & electrodes to cover majority of corrosive liquids. The technique called as “ Pulsed DC ” is used which offers very high zero stability & accuracy of measurement. The standard current output of 4-20 mA DC is provided which is linearly proportional to volumetric flow rate.

Principal Advantages :

  • Use of pulsed DC magnetisation & auto zero technique offers excellent long term zero stability.
  • Measurement is independent of velocity profile across the diameter of the pipe-line.
  • Measurement results are independent of density, viscosity, pressure, temperature , solid - impurities & conductivity variations [above 5 µs / cm].
  • No additional pressure drop across the meter which relieves the process designer while sizing his pumping requirements. Simple to install as no special precautions of straight pipe lengths required.
  • Compatible with virtually all corrosive / non-corrosive liquids.
  • Protection class offered IP 68.
  • Reasonably higher ratio of Return on Investment to Investment.

Applications

This meter is more suitable with those fluids which present difficulties in handling. Fluids such as effluents, slurries, pulps, brines & other highly corrossive liquids, acids & bases, fermenterwash, molasses etc.
Following industries can find lot of application of this flow measurement technique.

  • Sewage Treatment Plants.
  • Water Supply Schemes.
  • Steel & Aluminium.
  • Sugar Industries & Distilleries.
  • Pulp & Paper.
  • Chemical / Pharmaceutical.
  • Petrochemicals / Fertilizers.
  • Food & Drugs.
