Application Variables

Technology The ABLE range of turbine flowmeters offers high accuracy and reliability. A ferritic, stainless steel rotor revolves within a non magnetic housing on the outside of which is located a pick off coil containing a permanent magnet. As the rotor blades pass the tip of the permanent magnet, the reluctance of the magnetic circuit is changed and a small ac voltage is induced in the coil. The frequency of the ac voltage is proportional to flowrate, and the total number of pulses produced represents total flow passed through the meter.

Remote flowrate indication, alarms, totalising and batch control functions are available utilising our wide range of secondary electronic instruments, the subject of separate brochures. The flowmeter may be located some considerable distance from the associated secondary instrument.

Applications The flowmeters are suitable for use on lubricating and non-lubricating liquids of low to medium viscosity and are largely insensitive to density variations, pressure or temperature fluctuations.

No

A comprehensive range of sizes from 3/8” upward ensures ABLE turbines are configurable for most applications.

Flow

For normal transmission distance pre-amplifiers are not essential since pulse shaping and conditioning are carried out in the appropriate electronic readout unit. In cases where heavy electrical noise is present or where transmission distances are over 500 metres, pre-amplifiers of standard or intrinsically safe design are available as head mounted weatherproof units and loop powered.

Yes

Foam

Liquids

The electrical signal is a sinusoidal pulse of minimum height 50mV peak at lowest flowrate, rising to 800mV peak at max flowrate.

Variable

Features A unique feature of the design is the use of helically milled rotors cut from solid in sizes up to 65mm. Bearing bushes are of PTFE/Carbon HY49 or similar, or tungsten carbide depending upon nature of metered fluid.

In all cases, the spindle is of tungsten carbide with Cobalt binder, and thrust balls of tungsten carbide. Stainless steel ball races are used in the smaller sizes.

Sanitary Applications consequently have designed these flow meters with an absence of crevices where bacteria can lodge and breed. The materials of construction also ensures that no corrosive attack occurs when clean in place solutions are used.

ABLE have a number of specially designed variants for high accuracy flow measurement and batch control in the liquid food industries. In the basic design, ABLE were aware of the particular hygienic requirements of the brewing and diary industries and

Installation and use For best results the flowmeter should be installed well away from heavy current carrying cables and with control valves etc located downstream of the meter.

Meters may be installed in any attitude, but the flow direction and mounting attitude should be advised at the order stage if other than horizontal.

A length of straight pipe of bore equal to the meter inlet should be provided, preferably 10 diameters in length, and if possible containing flow straightening vanes at the inlet end. Turbine meters are sensitive to swirl and any pipe swirl present upstream may cause a change in meter factor.

Varying densities have no appreciable effect on the accuracy of axial flow turbine meters so far as volumetric flow is concerned. If readout is required in mass flow terms, we can supply density or temperature compensation equipment to automatically correct for density variation. All turbine meters are to some extent sensitive to viscosity changes and any likely viscosity variation should be advised at the order stage.

Strainers should be provided to minimise the risk of damage due to small solids in suspension.
