Methane CH4 5 Vol.-%

Product catalog summary

Product Overview
The FLOWEVO Infrared Gas Sensor for Methane (CH4) by smartGAS Mikrosensorik GmbH is a pre-calibrated, compact device designed for gas analysis, biogas applications, and environmental monitoring. It features 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 includes an LED status indicator.

Measurement Range: 0 to 5 Vol.-% Full Scale (FS)
Flow Rate: 0.1 to 1.0 l/min
Dimensions: 156 mm x 30 mm x 50 mm
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification

Measuring Response

Digital Resolution: 0.001 Vol.-%
Response Time: t90 ≤ 11.6 s (standard), ≤ 0.9 s (fast)
Detection Limit: ≤ 0.03 Vol.-% (standard), ≤ 0.07 Vol.-% (fast)
Repeatability: ≤ ± 0.05 Vol.-%
Linearity Error: ≤ ± 0.05 Vol.-%
Long Term Stability: Zero ≤ ± 0.044 Vol.-% over 1000 hours, Span ≤ ± 0.315 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 Information
The sensor 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 device's specifications are subject to change without notice, and users are advised to consult smartGAS for specific applications and recalibration needs.
