Stainless Steel Insertion Flow Transducer

INSERTION METERS

Quality and Simplicity in Flow Measurement

FLOMEC DP Technical Seminar Slide 2

FLOMEC Insertion Flow Meter provide a cost effective and simple means of measuring the flow of water and a wide rangeof low viscosity liquids.

OVERVIEW


A durable PVDF or peek rotor with a graphite -PTFE impregnated peek bearing rotates around a precision ground stainless steel rotor shaft to promote longevity. The body is all 316 stainless steel.

ROBUST FEATURES

FEATURES


INSERTION METER FEATURES

- All stainless steel construction - Dual independent pulse outputs- Direct input to PLC and Computer- High pressure submersible design- Pipe sizes 40-2500mm (1.5-100")- Electrical interference immunity- Minimal pressure loss - Simple to install- Low installed cost- Intrinsically safe electronics (optional)


INSERTION METER OPTIONS

• High temperature to 1500C (3000F)

• Reed switch option for hazardous area operation (intrinsically safe)

• Integral or remote high speed pre-set batch controller

• Optional Quadrature Hall (QP) pulse with bi-directional discriminator output

• Non magnetic rotor option for liquids containing ferrous suspensions.


INNOVATIVE DESIGN

The metering head of the Insertion Flowmeter 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 0.3 - 10 metres/sec, (1.0 -33 feet/sec) without creating flow cavitation.


INSERTION METER OUTPUTS

Dualpulse has as standard, two independent pulse outputs suitable for direct input to a wide range of ancillary instruments, PLC's and computers.

Both pulse outputs are rotor magnet activated and have a high level of immunity to electrical interference experienced with most other transducers of this kind.


HIGH LEVEL VOLTAGE PULSE

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.


INSERTION METER RATE/TOTALISATION OPTION

The FRT Series of Flow Rate Totalisers are field mount or remote instruments for accurate flow rate indication and totalisation of flow.The self powered FRT12 interfaces direct to the Insertion Meter without the need for external power. Alternatively the FRT12 can be loop powered via an optional 4-20mA output. The FRT12 is housed in a GRN (Glass Reinforced Nylon) enclosure that is completely watertight to IP67 (Nema 4X) classifications. Optional diecast aluminium alloy enclosure also available.Programming is done via the front keypad including flow K-factors, Engineering unit selection, 4-20 mA analogue Output Spans,High and Low Flow Alarms.

FLUID FLOW IN PIPES

Factors which affect the flow of a fluid in a pipe include:

- Velocity of 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

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.

Fig. 1 Ideal fluid velocity profile


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.

Fig. 2 Real fluid velocity profile

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.


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


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).
