1. Which type of flow meter is more suitable for measuring biogas? The most suitable flow meters for measuring biogas include vortex flow meters, electromagnetic flow meters, and thermal gas mass flow meters. The appropriate products can be selected according to the actual working conditions. 1. The vortex flowmeter works based on the Karman vortex principle, and calculates the flow rate by detecting the regular vortex frequency generated by the vortex generator. Advantages: Simple structure, easy installation, high precision measurement accuracy, wide range ratio, and can adapt to a certain temperature and pressure fluctuation range. Applicable scenarios: Suitable for situations where the composition of biogas is relatively clean and there are basic requirements for measurement accuracy
2. The electromagnetic flowmeter determines the flow rate by measuring the induced electromotive force generated by the cutting magnetic field of a conductive fluid based on Faradays law of electromagnetic induction. Advantages: High measurement accuracy, not affected by the density, viscosity, and temperature of biogas, and low pipeline pressure loss. Applicable scenarios: Suitable for scenarios where biogas contains certain moisture or impurities and requires high measurement accuracy for infiltration. 3. Thermal gas mass flow meters use the principle of thermal conduction to directly calculate mass flow rate by measuring the heat carried away by the gas flowing through the sensor. Advantages: It can directly output mass flow data without additional temperature and pressure compensation, has a large range ratio, and can also measure low flow rate biogas. Applicable scenarios: Suitable for situations where high measurement acc

2. What is a biogas flowmeter and what gases can be measured by a biogas flowmeter?
1、 The biogas flowmeter adopts the conventional differential pressure target biogas flowmeter principle, ensuring the durability, practicality, and long service life of the biogas flowmeter, while also providing the advantages of high measurement accuracy and good stability.
2、 The biogas flowmeter can mainly measure some flammable gases. The working principle of biogas flowmeter is that when the medium flows in the measuring tube, it generates a pressure difference with the target plate due to its own kinetic energy, resulting in a force on the target plate, causing a slight displacement of the target plate. The magnitude of the force is proportional to the square of the medium flow velocity, and its mathematical formula is: F=Cd · A ·ρ· V2/2F: the force acting on the target plate Cd: the fluid resistance coefficient A: the axial projection area of the target plate on the measuring tube ρ: the density of the medium under working conditions V: the characteristic flow velocity of the medium in the measuring tube. Precautions for biogas flowmeter: It is not allowed to directly install valves, bend width and tolerance heads at the front and rear ends of the measuring tube of the biogas flowmeter that greatly change the fluid flow state. If it is necessary to install valves, elbows, and other components on the front and rear pipelines of the biogas flowmeter, the length of the straight pipe sections should also be ensured as much as possible.
