Measuring and Control technology for Industrial Applications and Process Engineering

Pressure. Temperature. Level.

AFRISO is at home wherever there is measuring, controlling or monitoring required. As a full-range manufacturer, we offer our customers a broad product portfolio from a single source. Our product portfolio comprises proven pressure gauges, chemical seals and pressure transducers, mechanical and electronic thermometers as well as level switches, level indicators and innovative alarm units for a vast array of media. Customised special products, test and calibration instruments as well as handheld measuring instruments for service and maintenance complete this comprehensive range.

Adapted to suit specific industrial production processes, AFRISO MSR components meet the most stringent requirements. Our robust measuring devices deliver perfect measurement results and reliably monitor and control simple to highly complex processes – even under the most adverse conditions.

Our measuring instruments cover the following ranges:

  • Pressure: 0/2.5 mbar to 0/4,000 bar
  • Temperature: -50 °C to +1,100 °C
  • Level: 0/10 cm to 0/250 m

AFRISO also offers the required mounting accessories as well as suitable displays, controllers and evaluation units. Discover new possibilities for your applications – with AFRISO.

Gas analysis. Special applications.

The analysis of gas mixtures is an important part of industrial measuring technology. For continuous emission monitoring, AFRISO offers suitable measuring instruments such as tested and approved analysers as well as auxiliary equipment such as gas sampling probes, filters or coolers to allow for precise analysis of the gas components. On request, we provide complete engineering services all the way to commissioning of the turnkey analysis system.

Typical applications:

  • Emission measurement
  • Combustion processes
  • Large combustion systems
  • Turbo generator monitoring
  • Industrial gas filling
  • Incineration
  • Crematoria
  • Biological systems
  • Cooling plants
  • Purity measurements


Application example: Stationary gas alarm system

System for continuous monitoring for flammable or toxic gases as well as oxygen in ambient air. Up to four gas sensors can be connected – limit values can be set as required.

WATCHDOG-LINE alarm units – safety for building and plants

WATCHDOG-LINE alarm units report undesirable events, hazard and emergency conditions early so that immediate measures can be taken. The devices of the series excel with easy and intuitive operation. A large variety of probes and sensors enable fast detection of liquid levels, leakage and accumulations of liquids, gases or smoke. Integrated visual and audible alarms provide the appropriate signals in hazard conditions. Event reporting systems are also available for remote monitoring which report alarms to one or several recipients via GSM, Internet or E-mail. For easy integration into building automation systems, many devices are prepared for installation of a wireless module to allow for integration into the AFRISO smart home system or other systems based on EnOcean wireless.

Detectable media:

  • Water, waste water, groundwater, rainwater, heating circuit water
  • Cooling water
  • Fuel oil, diesel fuels and low-viscosity lubricating oils
  • Motor oils, gearbox oils and hydraulic oils
  • Vegetable oils and transformer oils
  • Antifreeze agents and fertilisers
  • Emulsions
  • Sludge, sand
  • Oil, petrol and grease layers
  • Conductive water mixtures and liquids
  • Gases and vapours
  • Many other liquids with a flash point of > 55 °C

Suitable service instruments for any application

AFRISO service instruments are professional solutions for adjustment work, maintenance and repairs. Perfectly adapted to each other, and also available as a smart, flexible and wireless sensor module system with the possibility of logging the measurement results via apps.
