To ensure optimal performance of a CIP system, it is critical to know the detergent concentration both in the loop and the make-up tank.

Our expertise in the field

Conductivity has the lowest maintenance and calibration requirements and enables you to reduce energy, chemical, and water usage. Endress+Hauser offers multiple conductivity sensor and transmitter options specifically designed for CIP applications. From compact entry-level to multi-channel systems with Ethernet integration capabilities.

• Optimize concentration measurement with the right conductivity sensor or transmitter for your application.

Know exactly what is in the line and remove the guesswork. Transition sensors determine when each phase of the CIP cycle ends and the next should begin.

Our expertise in the field

Conductivity, optical turbidity or pH sensors are used to determine when product or rinse water is in the line, starting the CIP system only if zero product remains after rinsing. Fast response is very important to reduce product and water loss and save time.

• Improve your phase separation by choosing the best fit sensor from Endress+Hauser’s liquid analysis portfolio.

Inventory of CIP detergents need to be monitored to ensure stable supply.

Our expertise in the field

Ultrasonic, guided or free-space radar are common methods for inventory monitoring of cleaning agents. Make-up, rinse and recovery tanks are commonly monitored with hydrostatic or capacitive sensors; selection is based on tank size and personal preference. Inventory safety is ensured by low/high level alarms and empty pipe detection (pump protection) and are usually done with tuning fork or conductive/capacitive sensors.

• Identify the best-fit level instrumentation for your application from a broad range of measuring principles and the associated portfolio of products.

Flow measurement is fundamental for an efficient CIP system. By ensuring a strong and turbulent flow, the desired scrubbing effect is reached.

Our expertise in the field

The Proline Promag H line is designed to handle the aggressive chemicals at elevated temperatures and higher than normal vibration due to turbulent flow. Endress+Hauser ensure performance for many years in CIP service. The flowmeters also include a temperature and conductivity output in addition to the flow value.

• Benefit from electromagnetic flowmeters which include a temperature and conductivity output in addition to the flow value.

Temperature within the CIP process can be measured at several locations and is closely controlled to ensure balance of the effectiveness of the cleaning and energy consumption. Often seen as a critical control point, temperature needs frequent calibration.

Our expertise in the field

iTHERM QuickNeck - our patented thermometer extension neck with quick release for fast and easy recalibration. One simple turning movement for opening and easy re-installation after calibration.

• Benefit from fault prevention and time savings using our temperature sensor iTHERM TM411 with QuickNeck technology.

Cleaning efficiency is based on temperature, detergent concentration and flow velocity/shear forces at the installation walls. But as the pipes are not always straight and the reach of the spray balls is not always ideal, there are spots which are difficult to clean. To determine and improve the overall cleaning efficiency, it is necessary to also monitor the cleaning behaviour at these spots.

Our expertise in the field

Our compact multiparameter device Liquitrend QMW43 can simultaneously measure the adhesion thickness and conductivity of media. Installed at critical points in the food processing plant, it reliably monitors fluid behavior and informs whether residual buildup is present after cleaning. This innovative technology allows the cleaning frequency and intensity to be tailored to the needs of a plant, thus increasing efficiency.
