Macnaught MX Series of Oval Gear Flow Meters

  1. 1. Oval Gear Flow Meters & MX Series Overview
  2. 2. Presentation Overview 1.Flow meter technology 2.Positive Displacement - Principle of operation. 3.Ideal applications 4.What's new 5.Introducing the new generation MX series Flowmeters.
  3. 3. Flow Meter Technologies There are 4 general groupings by which a flow meter can be categorised, according to the technology adopted.  Velocity  Inferential  Mass  Volumetric
  4. 4. Volumetric Flow Meter ‘Directly measure the total volume of the fluid passing through the pipe’  Oval Gear  Rotary  Nutating Disc  Bi-Rotor  Spur Gear  Oscillating Piston
  5. 5. Typical Applications Volumetric • Batching • Dispensing • Dosing • Fuel Consumption • Applications requiring accurate totals
  6. 6. Positive Displacement Flow Meter
  7. 7. Principle of Operation A precision engineered measuring chamber houses a pair of oval rotors which rotate during flow conditions
  8. 8. Principle of Operation As the Rotors turn they sweep a measured volume of liquid through the measuring chamber Measured Volume
  9. 9. Principle of Operation • Each of the Rotors are fitted with magnets on the top face. • As the Rotor turns the magnet activates a switch which is fixed to a Printed Circuit Board (PCB) • This in turn generates a Pulse Output
  10. 10. Principle of Operation Our Sensor Boards (PCB) incorporate two types of switches.  Reed Switch Mechanical Switch  Hall Effect Switch Solid State
  11. 11. Calculating Flow Rate • The K- Factor is … ‘The number of Sensor Pulses per Unit of Measure’ (Litre or US gallon) • Each meter is assigned an individual K-Factor calculated during our calibration checks Example ….  A meter has an independent K-Factor 36 (= 36 pulses per litre)  Each pulse generated by the meter is the equivalent to 1 Ltr ¸ 36 = 27.8 ml  An Electronic device (Signal Conditioner) is used to convert these pulse outputs to Flow Rate and Total Flow
  12. 12. The Benefits associated with a PD Meter
  13. 13. Technical Specifications  Accuracy • +/- 0.5% (500ml in every 100 litres)  Repeatability • 0.03% (30ml in every 100 litres)
  14. 14. Installation and Commissioning  Reliable  Robust  Easily maintained on site  No pipe conditioning required  Suitable for variations in medium (e.g. viscosity, concentrations, etc. )
  15. 15. Suitable Applications
