Methane CH4 100 Vol.-% Biogas

Product catalog summary

Product Overview: The FLOWEVO infrared gas sensor by smartGAS Mikrosensorik GmbH is designed for biogas applications, specifically for detecting Methane (CH4) at concentrations up to 100 Vol.-%. It features a compact design, pre-calibration, and supports Modbus ASCII or RTU communication.

Specifications: The sensor operates on a Non-Dispersive Infra-Red (NDIR) dual wavelength principle, with a measurement range of 0 to 100 Vol.-%. It requires a gas flow rate between 0.1 to 1.0 l/min and operates at nearly atmospheric pressure. The sensor dimensions are 76 mm x 30 mm x 50 mm, with a warm-up time of less than 2 minutes for start-up and less than 30 minutes for full specification.

Performance: The digital resolution is 0.01 Vol.-%, with a response time of ≤ 9.9 seconds for standard and ≤ 0.7 seconds for fast response at 0.7 l/min. The detection limit is ≤ 0.2 Vol.-%, and repeatability is ≤ ± 0.6 Vol.-%. Long-term stability is ≤ ± 1.0 Vol.-% for zero and ≤ ± 2.0 Vol.-% for span over 1000 hours.

Environmental and Electrical Parameters: The sensor operates within a temperature range of 0 to +50 °C and can be stored between -20 to +60 °C. It supports a supply voltage of 3.3 to 6.0 VDC, with a peak supply current of < 400 mA at 3.3 V. The average power consumption is < 800 mW.

Installation and Calibration: The sensor includes options for gas coolers, particle filters, and gas pumps. Calibration is performed via software for zero and span adjustments. The sensor requires a clean, particle-free gas sample with a dew point below +5°C.

Additional Information: The document emphasizes the importance of recalibration depending on application and ambient conditions. It also notes that specifications are subject to change and advises consulting smartGAS for specific application requirements.
