How Can Flow Control Save Costs?

Precise flow measurement significantly reduces costs by preventing resource loss and optimizing usage. High-accuracy flow meters ensure precise quantity and volume measurement, minimizing waste and improving process control. This accuracy enables recipe optimization and better blending control, ensuring consistent quality and efficiency in production. By adhering to exact quantities of valuable resources, you reduce waste and improve overall product quality.

How Can a Flow Switch Save Costs?

Flow switches play a critical role in cost prevention by detecting system malfunctions that can lead to operational downtime. When flow stops, pumps can run dry, or Clean-in-Place (CIP) processes may fail to meet standards. These issues can result in costly downtime or product loss. Anderson-Negele flow switches provide early malfunction detection, allowing quick corrective action to protect equipment and maintain continuous operation.

Available Flow Measurement Methods:

Anderson-Negele offers four primary flow measurement technologies for liquid applications:

Electromagnetic Flow Measurement
Turbine Flow Measurement
Coriolis Mass Flow and Density Measurement
Calorimetric Flow Switches

Scroll down for detailed descriptions of each technology and their benefits.

What is Electromagnetic Flow Measurement?

Electromagnetic flow measurement is based on Faraday’s law of induction. A magnetic field is generated within the meter, and as conductive liquid flows through, it induces a voltage proportional to the fluid’s velocity. This measurement method is highly accurate and provides output in the form of a counting pulse, 4-20mA signal, or digitally via IO-Link.

Suitable Products for Electromagnetic Flow Control

Electromagnetic flow meters are ideal for liquids with a conductivity greater than 5 μS/cm, such as milk, cream, beer, ketchup, sauces, molasses, yogurt, and cleaning agents.

What is Turbine Flow Measurement?

Turbine flow meters use non-contact pulse measurement. The turbine rotor, positioned within the liquid flow, rotates as the liquid passes through. A signal probe generates an electromagnetic field, and the rotating rotor interacts with the field to produce an induction current, which is measured and outputted with precision.

Suitable Products for Turbine Flow Meters

Turbine flow meters are an economical and precise alternative for non-conductive, aqueous media like fruit juice, beer, alcohol, oils, and process water. They are also ideal for demineralized water and cleaning media.

What is Coriolis Mass Flow and Density Measurement?

In a Coriolis flow meter the fluid is split into to tubes. An active device forces these measuring tubes to oscillate. At zero flow, the two tubes vibrate in phase with each other, the sinus waves are parallel. When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift of the sinus waves. The time difference between the waves is measured and is directly proportional to the mass flow rate.

Mass and volume flow measurement: These values are calculated from mass flow rate and the density measurement.

Density measurement: The measuring tubes are vibrated at their natural frequency. A change in the mass of the fluid contained inside the tubes causes a corresponding change to the tube natural frequency. The frequency change of the tube is used to calculate density.

Suitable Processes for Coriolis Flow Meters

Coriolis meters are perfect for food and beverage processes where both flow rate and density (such as Brix, Plato, Proof, or Baumé value) must be measured. They are especially useful in applications requiring simultaneous flow and density control.

What is a Calorimetric Flow Switch?

Calorimetric flow switches use a temperature sensor heated periodically to detect flow. As liquid flows over the sensor, it draws heat away, and the temperature difference indicates flow velocity. Anderson-Negele’s design reduces response time and improves measurement accuracy.

Suitable Products for Calorimetric Flow Switches

This measuring principle is ideal for all aqueous products, including demineralized and highly filtered media such as cola and other soft drinks, filtered beer, demineralized water, as well as for media in pressure lines.

Flex-Hybrid Technology with IO-Link 4…20mA Parallel

Anderson-Negele’s Flex-Hybrid technology combines the advantages of both digital IO-Link and analog 4-20mA transmission. This dual capability simplifies the transition from analog to digital systems. The FMQ flow meter can be easily switched between digital and analog modes with a simple cable change, providing flexibility in system upgrades. The system also uses a standard 3-pole cable, saving time and installation costs.
