1. What type of flowmeter should be selected for measuring biogas conditions?

Based on different application scenarios of biogas conditions, I have compiled a comparison of 5 flowmeter models with strong adaptability and core parameters. OPTISONIC 7300 Biogas Ultrasonic Flow Meter - Suitable for dry/wet low-pressure biogas measurement with high CO ₂ content, suitable for landfill and sewage treatment scenarios - Core parameters: single/dual channel optional, flange diameter DN50-200/2-8 inches, maximum pressure rating PN10/ASME Cl 150, range ratio 100:1, integrated gas volume correction and methane content measurement function 2 Heshunda VN Series Turbine Flowmeters - Adaptation Scenarios: Conventional biogas flow measurement, suitable for small-scale biogas use - Core Parameters: Accuracy Class 1.0, Working Pressure 0.6-2.5MPa, Working Temperature -200 ℃~-30 ℃, Basic Measurement Range 15m ³/h, Available in VN-1

5, VN-2

5, VN-45 and other caliber models. There is also an intelligent vortex street biogas flowmeter of the same brand that can adapt to a wider range of scenarios VTON imported biogas vortex flowmeter from the United States - adaptation scenarios: biogas with complex composition and large flow rate fluctuations, working conditions containing a small amount of water vapor and trace particles, installation scenarios with insufficient straight pipe sections - core advantages: strong adaptability to the fluctuation of biogas composition, few installation restrictions, suitable for gas supply measurement in biogas power plants, gas production monitoring in biogas digesters in agricultural and pastoral areas, not suitable for pipelines containing a large amount of condensate, particulate

matter or strong water hammer LWQ series speed type biogas flowmeter - adaptation scenario: industrial grade biogas measurement scenario with multiple specifications of diameters - core parameters: nominal diameter DN25-DN300 optional, ambient temperature -25 ℃~+80 ℃, medium temperature -20 ℃~+60 ℃, supports multiple output modes such as pulse and current, and can choose power supply scheme according to needs WST-000B7 Biogas Flow Meter - Adaptation Scenarios: Measurement of Pure, Contaminated, and Corrosive Biogas Media, Ultra Large Diameter Operating Conditions - Core Parameters: Diameter DN15-DN3000mm, nominal tapping pressure 0.6-42MPa, operating temperature -200 ℃~500 ℃, accuracy ± 0.2~± 1.5% FS, no movable parts, supports multi material selection and built-in self checking program | Model | Measurement Principle | Adaptation Scenario Advantages | Core Parameter Range | | -----------------------------------------------------------------------------------------------------Street | Conventional biogas site, small-scale project | Accuracy 1.0 level, 0.6-2.5MPa, 15m ³/h basic range | Weidun VTON vortex | Vortex street | Composition fluctuation, insufficient straight pipe section scenario | Biogas power generation, farm monitoring, prohibited for high condensate scenarios | | LWQ Series | Speed Type | Industrial Multi Path Biogas Measurement | DN25-DN300, -20 ℃~+60 ℃ Medium Temperature | | WST-000B7 | Differential Pressure/Sensor Combination | Large Diameter, Corrosive/Dirty Biogas | DN15-DN3000, ± 0.2~± 1.5% FS Accuracy |
