FLOW EVO CH4 10 Vol.-%

Product catalog summary

Product Overview: The FLOWEVO Infrared Gas Sensor for Methane (CH4) by smartGAS Mikrosensorik GmbH is designed for detecting methane concentrations up to 10 Vol.-%. It features a pre-calibrated, compact design with a 3/5 mm gas line connector and operates on a 3.3–6 V DC supply voltage. The sensor supports Modbus ASCII or RTU communication and indicates status via an LED.

Applications: The sensor is suitable for biogas applications, environmental monitoring, and gas analysis. Additional equipment available includes a gas cooler, particle filter, gas pump, calibration software, and mounting equipment.

Technical Specifications:

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength.
Measurement Range: 0 to 10 Vol.-% Full Scale (FS).
Flow Rate: 0.1 to 1.0 l/min.
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification.
Response Time: t90 (10 to 90% FS) ≤ 9.9 s standard, ≤ 0.7 s fast.
Detection Limit: ≤ 0.05 Vol.-% standard, ≤ 0.10 Vol.-% fast.
Repeatability and Linearity Error: ≤ ± 0.1 Vol.-%.
Long Term Stability: Zero ≤ ± 0.2 Vol.-% over 1000 hours, Span ≤ ± 1.5 Vol.-% over 1000 hours.

Environmental and Electrical Parameters:

Operating Temperature: 0 to +50 °C.
Storage Temperature: -20 to +60 °C.
Air Pressure: 800 to 1150 hPa.
Humidity: 0 to 95% relative humidity (non-condensing).
Supply Voltage: 3.3 V to 6.0 VDC.
Power Consumption: Average < 800 mW.

Additional Notes: The sensor's performance is influenced by temperature, pressure, and flow rate. It requires a stable gas dew point of less than +5°C and a clean, particle-free sample gas. Calibration is recommended at first initiation and periodically thereafter. The document emphasizes that specifications are subject to change and advises consulting smartGAS for specific requirements.
