Analytical measurement

Environmental protection, product quality assurance, process optimization and safety are just some of the reasons why liquid analysis is becoming an increasingly necessary task.

Liquids like water, soft drinks, dairy products, chemicals and pharmaceuticals need to be tested every day. From standard sensors to complete analytical stations - we provide innovative technology for the analysis of all parameters in liquid applications.

Analytical measurement system

The typical configuration of an analytical measurement system is made up of the four elements and there are also variants of equipment that can do without some of them.

Transmitter

Connection cable

Sensor

Sensor holder

Transmitters

Transmitters are an essential part at the point of measurement. They process the value measured by the sensor and display it for further processing. They allow the measurement point to be exactly adjusted to the operating and process conditions while performing regulation tasks.

Endress+Hauser transmitter concept includes Liquisys transmitters and Liquiline platform. The latter offers from economical Liquiline CM14 equipment of a single parameter to high performance Liquiline CM42 with a 2 thread tech or the multichannel and multiparameter Liquiline CM44. This controller lets you connect up to 8 sensors at the same time with Memosens technology for any parameter combination. It presents an integrated web server that allows the user remote access to device’s parameters through any Internet browser. It also provides digital protocols such as, HART, PROFIBUS, EtherNet/IP or Modbus for a complete integration in process control.

Sensors

Analytical sensors are installed in field and are the ones measuring the process using measuring principles such as: amperometric, ion-selective electrode, potentiometric, optical, conductivity, induction, etc. The signals are processed digitally using MEMOSENS technology that guarantees precise and reliable measurements in your process.

Along with this new technology the sensor has an internal memory where the different process data and calibration values are stored, which allows along with digital technology to take them off the process and do the calibration in the lab.

ADVANTAGES

  • Corrosion issues associated to analog sensors are eliminated
  • It makes it easier for in-lab calibration and the exchange of pre-calibrated sensors with the ones in the process
  • Noise is avoided in the transferring of information
  • Connection of up to 8 sensors in the same transmitter, measuring different parameters of the analytical line

Platform complemented by Liquiline Compact, single parameter transmitter for Memosens sensors. It is especially suited for limited space mounting and can be used with any smartphone or tablet via Bluetooth.

Parameters that can be measured:

  • pH/redox
  • Conductivity
  • Turbulence Model / SST
  • Dissolved Oxygen
  • Free Chlorine/ Total Chlorine
  • Chlorine Dioxide
  • Ozone
  • Nitrates / Nitrites
  • Ammonium
  • Phosphates
  • COT
  • DQO
  • CAE (SAC)
  • Colour
  • Biomass/Cellular growth
  • Chromate
  • Iron
  • Aluminum
  • Hardness
  • Sod

Memosens technology

Memosens technology is revolutionizing fluid analysis. It converts the measured value into a digital signal in the sensor and transfers it to the transmitter via contactless. This means that humidity and corrosion which distort the medium value or make the measuring point fail, they have no chance.

Memosens sensors can even be connected underwater. Also, the transmitter will actively let you know if there is an interruption in the signal. The result is maximum reliability in data transfer, a spectacular increase in the availability of the measuring point and guarantee that the process will be conducted safely.

ADVANTAGES

Automatic sensor recognition allows you to replace them without problem

Less inactive time in the process, since sensors are calibrated in the lab

More precise process management since sensor maintenance can be programmed without any unwanted surprises

Predictive maintenance as an integral part of sensor technology, which translates into a better plant management
