DO YOU KNOW EXACTLY WHAT IS IN YOUR PIPELINE?

During production and CIP, different liquids move through the same system:

Product → Water → Caustic → Rinse Water

If the change from one medium to another is not detected accurately, valuable product, water and cleaning chemicals can be lost.

Conductivity measurement helps identify these process transitions in real time, allowing the control system to respond when conditions change—not simply when a timer expires.

This can contribute to:

✔ Reduced product losses
✔ Reduced chemical losses
✔ Lower water consumption
✔ Less waste
✔ More controlled and repeatable processes

The real value is not only in measuring conductivity.

The value comes from using that information to improve process control.

Our new One Process Improvement series looks at practical ways instrumentation can contribute to better process performance.

WHY IS YOUR CIP CYCLE TAKING LONGER THAN IT SHOULD?

A CIP system can be programmed to run for a specific amount of time.

But time alone doesn't tell you what is actually happening inside the process.

During CIP, the process moves between different media — water, caustic, acid, rinse water and product — each with different conductivity characteristics.

By measuring conductivity inline, the system can detect changes in the process medium and help identify when a transition has actually occurred.

Water → Caustic → Water → Product

This can support a move from time-based control to condition-based control.

The result?

Potentially less water.
Less chemical loss.
Less product loss.
More controlled CIP cycles.
More production availability.

Our new One Process Improvement series explores how conductivity measurement can contribute to better process control.

Product Loss & Phase Separation
KNOW WHAT'S IN THE PIPE.

During CIP and production changeovers, accurately identifying the transition between product, water, acid and caustic can prevent unnecessary resource and product losses.

The Anderson-Negele ILM-4 uses inductive conductivity measurement to provide fast, accurate phase separation.

That means:
Less product loss.
Less chemical loss.
Less water consumption.
Better process control.

With a response time of 1.2 seconds, the ILM-4 enables active, automated phase transition rather than relying on preset time control.

From approximately R22,000.

ENGINEERING INSIGHTS: Conductivity Measurement | Part 4 of 4

Conductive vs Inductive: Making the Right Choice

Which conductivity sensor is better?

The answer is: it depends on the process.

Conductive and inductive conductivity sensors use fundamentally different measurement principles, and each has applications where it is better suited.

A good instrumentation decision considers much more than the conductivity range.

You also need to consider:
🔹 Product characteristics
🔹 Temperature and pressure
🔹 Fouling potential
🔹 Cleaning requirements
🔹 Hygienic design
🔹 Required measurement accuracy
🔹 Maintenance expectations
🔹 Total lifecycle cost

The most suitable sensor isn't simply the one that can measure the process. It is the one that can continue to provide accurate and reliable measurement throughout the life of the installation with the lowest practical maintenance requirement.

Engineering Takeaway:

The right conductivity sensor is determined by the process—not simply the conductivity range.

STOP TIMING YOUR CIP. START MEASURING IT.

CIP doesn't need to run for a predetermined amount of time.

The Anderson-Negele ILM-4 Inductive Conductivity Sensor enables inline measurement of cleaning media, allowing phase transitions to be detected accurately and automatically.

The result?
→ Minimum cleaning time
→ Reduced water consumption
→ Precise cleaning-agent concentration
→ Less resource loss
→ More reproducible CIP results

With a response time of just 1.2 seconds, the ILM-4 is designed for fast, efficient process control.

ILM-4 available from approximately R22,000.

ENGINEERING INSIGHTS: Conductivity Measurement | Part 3 of 4

Inductive Conductivity Sensors

What happens when the process itself makes direct-contact measurement difficult?

Fouling. Scaling. Aggressive chemicals. Hygiene requirements. And increased maintenance.

Inductive conductivity sensors eliminate direct electrode contact with the process liquid, using electromagnetic induction to measure conductivity.

This makes them particularly suited to demanding applications such as:
🔹 CIP systems
🔹 Food & beverage processing
🔹 Breweries and dairies
🔹 Chemical processing
🔹 Acid and caustic concentration control
🔹 Product-to-water interface detection

But no measurement technology is right for every application. Inductive sensors also have limitations, particularly when measuring extremely low conductivity liquids.

In Part 3 of our Engineering Insights: Conductivity Measurement series, we look at how inductive conductivity sensors work, their advantages and limitations, and where they are best applied.

Engineering Takeaway:

Inductive conductivity sensors are particularly suited to processes where fouling, aggressive media, hygiene and low maintenance make direct electrode contact a limitation.
