Memosens: the success of a revolution

12 years of Memosens digital technology

Endress+Hauser's market launch of Memosens technology in the spring of 2004 saw the beginning of a success story. Memosens revolutionised operation and maintenance in the field of liquid analysis to the extent that one in two sensors sold today is fitted with the technology. Complete measuring points with Memosens technology are now available for all relevant liquid analysis parameters and there is almost no limit to their potential use.


  • Eliminate measurement errors: non-contact digital data transmission avoids the effects of moisture, corrosion and salt bridges with alert messaging if the signal transmission is disturbed.

  • EMC safety guaranteed: galvanic isolation ensures interference-free measurement.

  • User-friendly operation: calibration under favorable lab conditions, lockable bayonet connector, plug & play with automatic sensor recognition.

  • Reduced operating costs: Simple sensor exchange using pre-calibrated sensors reduces process downtime and regular regeneration extends sensor lifetime.

  • Data management at its best: storage of calibration, sensor and process data facilitates more precise process management and optimized maintenance strategy (predictive and preventive maintenance).

DS Smith: Memosens digital sensors

When packaging giant DS Smith wanted to closely monitor watewater discharge and ensure compliance with regulations, Endress+Hauser was called in to help at Kelmsley Mill in Kent. Find out more >>

Harvest Biofuels: Memobase Plus

Being able to accurately measure pH is an important part of the biodiesel production process, as the pH value affects the viscosity of the final product. Regular calibration is essential to ensure an accurate reading but the maintenance engineers were finding calibration difficult and time-consuming. Our Memobase Plus software saved the day >>

South Staffs Water: Turbimax CUS71D

As part of a refurbishment process, South Staffs Water wanted to investigate what efficiency savings and operational improvements could be made, including automating the measurement of the sludge blanket. See how our Turbimax CUS71D ultrasonic interface sensor provided the ideal solution >>

Agnico Eagle: Memosens pH measurement

Agnico Eagle's gold mine in Kittilä, Finland, is the largest primary gold producer in Europe. Agnico Eagle was not satisfied with existing pH measurements as they were inaccurate and calibration was taking up a considerable amount of time and resources. With our Memosens digital technology, confidence in pH measurement is restored and up to a 90% reduction time spent on calibration and field repairs has been achieved!Find out how >>
