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. Price of chemical flow meters
The price of chemical flow meters varies greatly depending on the type, accuracy, material, and function, ranging from a few hundred yuan to several hundred thousand yuan.
Main types and price range of Coriolis mass flow meters without ridges: low-end (500 yuan -20000 yuan, accuracy 0.5% -1%), mid-range (20000 yuan -100000 yuan, accuracy 0.1% -0.5%), high-end (100000 yuan -69000 yuan+, accuracy ≤ 0.1%). Electromagnetic flow meters: 2000-20000 yuan (taking Qingtiantec as an example, pipe diameter and material affect price). Vortex flow meters before drying: 1000-3000 yuan (taking Qingtiantec as an example, suitable for high-precision liquid measurement). Vortex flow meters: 800-2500 yuan (taking Qingtiantec as an example, suitable for gas/steam). Ultrasonic flow meters: 1500-15000 yuan (non-contact measurement, accuracy determines price). Elliptical gear flow meters: 1000-3000 yuan (special for high viscosity liquids). 2 Key price influencing factors • Accuracy level: For every 0.1% increase in accuracy, the price may double (such as Coriolis flow meters) • Material cost: 316L stainless steel is 30% -50% more expensive than regret limb carbon steel, and special materials such as Hastelloy have a higher premium • Explosion proof certification: Chemical explosion-proof types are 40% -100% more expensive than ordinary types • Pipe diameter size: Large caliber instruments with a diameter of DN300 or more have an exponential increase in price Typical application scenario cost - Basic chemical transportation: optional electromagnetic or vortex flowmeter (5000-15000 yuan) - High precision ingredients: r
