  1. FLOMEC Insertion Paddle Wheel Flow Meter / Monitor For Low Viscosity Liquids

  2. FLOMEC Introduction • Insertion Paddle Wheel Flow Meter / Monitor • Cost effective. • Simple means of measuring the flow. • Wide range of low viscosity liquids. Operating principle Flow passes through a pipe causing the rotor to spin. Magnets installed in the rotor pass by pulse sensors within the transducer body & inturn this produces frequency outputs proportional to flow rate.

  3. Flomec Robust Features • Insertion Paddle Wheel Flow Meter / Monitor • Durable PVDF or PEEK rotor. • Graphite - PTFE impregnated peek bearing. • Precision ground stainless rotor shaft. • 316 stainless steel body.

  4. Flomec Paddle Wheel Features • All stainless steel construction • Dual independent pulse outputs • Direct input to PLC and Computer • High pressure submersible design • Pipe sizes 1.5” to 100” (40-2500mm) • Electrical interference immunity • Minimal pressure loss • Simple to install • Low installed cost • European CE compliant.

  5. Flomec Paddle Wheel Options • High temperature to 4000F (2000C) • Reed switch option for hazardous area operation (intrinsically safe) • Integral or remote high speed preset batch controller • Optional Bi-directional discriminator • output • Non magnetic rotor option for liquids containing ferrous suspensions.

  6. Flomec Innovative Design The metering head of the Paddle Wheel is shaped to encourage a conditioned flow profile at the aerofoil shaped rotor. The combination of these unique features extends the linear measuring range to cover flow velocities from 1.0 - 33 ft/sec (0.3 - 10 metres/sec), without creating flow cavitation.

  7. Flomec Paddle Wheel Outputs • Standard, two independent pulse outputs • Suitable for direct input to a wide range of ancillary instruments, Z3 Totalizer, PLC's and computers. • Both pulse outputs are rotor magnet activated. • High level of immunity to electrical interference experienced with most other transducers of this kind.

  8. Flomec Outputs High Level Voltage Pulse - A self generating pulse output requiring no power source, produces a strong 1.5 volt output spike of approx. 10 micro seconds duration with no dependence on rotor speed. Square Wave Output - An open collector pulse output produced by a solid state Hall Effect device. This three wire device requires 5-24VDC excitation voltage and produces a high resolution NPN square wave conditioned output.

If there is any likelihood of air entrainment in a horizontal pipe do not locate the flow transducer in the 12 o’clock position.

  12. Flomec Fluid Flow in Pipes Factors which affect the flow of a fluid in a pipe include:- - Velocity of the the fluid (mean velocity) - Viscosity of the fluid - Density of the fluid - Diameter of the pipe - Pipe friction where the fluid is in contact with the pipe. Fig. 1 Ideal fluid velocity profile If we ignore the effects of viscosity and the pipe friction, a fluid wouldtravel through a pipe in a uniform velocity across the diameter of thepipe. The 'velocity profile' would appear as in Fig 1.

  13. Flomec Fluid Flow in Pipes However, this is very much an 'ideal' case and, in practice, viscosity effects the flow rate of the fluid and works together with the pipe friction to further decrease the flow rate of the fluid near the pipe wall. This can be represented in Fig 2. The most important of the factors effecting fluid flow in pipes can be pulled together in one dimensionless quantity to express the characteristics of flow. This is known as the Reynolds Number. Fig. 2 Real fluid velocity profile

  14. Fluid Flow in Pipes At very low velocities, the dynamic force will be low and, therefore, the Reynolds Number will be small. Similarly, a high viscosity fluid will result in low Reynolds Number. This will result in viscous forces holding back the fluid flow at the pipe walls with the highest fluid velocity at the centre of the pipe. This is similar to Fig 2. Except that the velocity profile is a parabola (see Fig 3.). It is known as laminar flow and normally occurs at Reynolds Numbers below 2000. Fig. 3 Laminar Flow Flomec

  15. Fluid Flow in Pipes When Reynolds Numbers are above 2000 i.e. high velocities and/or low viscosities, the flow breaks up and Turbulent flow occurs with a much flatter velocity profile (see Fig. 4). Fig. 4 Turbulent flow velocity profile In the process world, unless very viscous fluids are being piped, turbulent flow is the norm. This is certainly the case for steam where Reynolds numbers well in excess of 2000 are encountered. Flomec
