FLOWEVO – NDIR Sensors for Process Measurement

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.

Easy OEM Integration

BASICEVO sensors can easily be integrated into OEM systems, where long term stability, repeatability and reliable performance are required. It can be utilised as a refrigerant detector in industrial refrigeration facilities but can also be used for ambient air monitoring in the field of air conditioning devices. Other scopes of applications comprise continuous gas monitoring in controlled environment chambers and food storage rooms as well as usage for various areas of scientific research. Special build-in solutions to provide IP54 protection and easy field gas calibration are available.

Flexible Data Connectivity

Modbus ASCII or RTU data communication offer a variety of options to connect the BASICEVO gas sensor to a controller.

Versatile usability - your advantages with the EVO series!

The sensors of the EVO series are reliable, compact and powerful. Unlike many other NDIR sensors, they combine best performance with a small mechanical design. The standardized platform makes it possible to combine various EVO sensors into a complete solution in many applications. As a result, development time, storage and operating costs and not least maintenance and logistics costs can be significantly reduced.

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.
