FLOWEVO from smartGAS

NDIR sensors from smartGAS offer many advantages for successful process measurement and are therefore ideal for use in process control. They have a large spectrum of measurable gases and are especially convincing where it is important to have the utmost precision and reliability. Different versions can be very easily combined, also facilitating complex measuring tasks. All smartGAS sensors are designated by low detection limits, very small drift, a large temperature range and a fast response time and markedly low operating and maintenance costs

Our NDIR sensors in the FLOWEVO series combine measuring precision with compact design and simple handling. We have minimised sizes considerably, without having to make compromises in terms of performance.

Detailed information on the product

Here you will find an overview of the product data sheets. Additional Gases are available on request. Please contact us for an individual consultation.

Service and parameterisation via Calibration Tool:

The Calibration Tool allows users of the FLOWEVO series to perform services on the sensor and check various functions. Using the smartGAS USB adapter (item no.: Z6-000025 or Z6-000026), the sensor can be easily connected and read out through to a PC or notebook. In addition to calibrating the zero and end point, the response time t90 or the Modbus address can be set and a test report on the sensor's status can be generated.
