1.1 Sanitary and hygienic solution

The OPTIFLUX 6000

OPTIFLUX 6000 electromagnetic flow sensor is specifically designed to stay clean and

OPTIFLUX 6000OPTIFLUX 6000 sterile in compliance with the most stringent demands prevailing in the food & beverages and pharmaceutical industries. There are no crevices, gaps or blind spots and the flow sensor offers full CIP/SIP possibilities. The flow sensor is conform FDA food contact material requirements, for all wetted materials and is certified in accordance with EHEDG and 3A.

The flowmeter provides easy installation and commissioning and is available with the flow converter seperate, or mounted directly on the flow sensor.Therefore it can be installed in places difficult to access due to for example high temperatures or vibrations. The converter is also available in a stainless steel housing for applications when for example regular cleaning procedures with aggressive cleaning agents, may attack a standard polyurethane coating.

In addition to weld-end connections, this KROHNE flow meter offers a large number of other hygienic connections, including DIN 11851, DIN 11864, clamp and SMS.

Because of its high accuracy, a precise measurement of the medium is possible enabling an accurate measurement of flows whether it is required for blending, dosing or batching. Furthermore its accuracy is maintained even in case of pulsating flows. When a medium has a low conductivity for example in case of glucose or fruit concentrates, the device continious to deliver an optimal performance.

PRODUCT FEATURES

Due to its reinforced liner the OPTIFLUX 6000 is an optimal solution for applications where high temperatures or vacuum impacts can occur. The certified hygienic construction is also available for larger diameters up to DN150, as volumes are increasing and larger pipe sizes are needed with fast increase in the industrial production of beer, wine, milk and other beverages.

1.2 Options

PRODUCT FEATURES

Reinforced PFA liner

Reinforced PFA linerReinforced PFA liner The OPTIFLUX 6000 has an FDA conform PFA liner with an integrated stainless steel reinforcement that ensures vacuum resistance and long-term dimensional stability. The reinforced PFA liner makes sure that the flowmeter keeps its form stability even at high temperatures and very low pressure or vacuum. Therefore the OPTIFLUX 6000 remains its accuracy over time.

Unique gasket adapter concept

Unique gasket adapter conceptUnique gasket adapter concept A special sealing concept for stainless steel adapters has been designed with support of TNO, a member of the European EHEDG organization. The sealing concept provides for a smooth and dimensionally stable measuring section between the two process connections. It prevents the gasket from expanding into the measuring tube because during CIP / SIP cleaning procedures, the gasket expands into an expansion chamber. This leads to a sharp sealing at the edge of the pipeline and a perfect transition into the measuring section. In addition, the gasket experiences less stress which results in a longer life time and reduced maintenance.

Hygienic Converter housing

Hygienic Converter housingHygienic Converter housing The sensor can be complemented with an IFC 100 converter housing made of stainless steel 1.4404. This stainless steel converter housing for the Food and Beverage Industry is specially designed to ensure easy cleanability and resistance to regular rinsing with detergents A mounting angle of 10 degrees avoids pooling and the special EPDM sealing all around, minimises crevices. Furthermore, the display is made entirely of polymer and can be used in "no glass" designated zones.

1.3 Measuring principle

An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of the fluid, a voltage U is generated: U = v * k * B * D

U = v * k * B * D

U = v * k * B * DU = v * k * B * D

in which: v = mean flow velocity k = factor correcting for geometry B = magnetic field strength D = inner diameter of flowmeter

The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and convert it into signals for totalizing, recording and output processing.

2.2 Measuring accuracy

Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration validates the performance of the flowmeter under reference conditions against accuracy limits.

The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect of linearity, zero point stability and calibration uncertainty.

Reference conditions

• Medium: water

• Temperature: +5...35°C / +41...95°F

• Operating pressure: 0.1...5 barg / 1.5...72.5 psig

• Inlet section: ≥ 5 DN

• Outlet section: ≥ 2 DN
