2. What are the types of flow meters for fractionation tower pipelines?

Fractionation tower pipeline flow meters mainly include differential pressure, volumetric, float, electromagnetic, vortex, ultrasonic, and Coriolis mass types. Differential pressure flow meters use the pressure difference generated when fluid flows through throttling elements to measure flow rate, which is common in the inlet and outlet pipelines of distillation towers. Orifice flowmeter: simple structure, low cost, high temperature and high pressure resistance, but with large pressure loss and moderate accuracy, requiring differential pressure transmitter for use. V-cone flowmeter: high accuracy, low pressure loss, strong anti-interference ability, suitable for measuring impurities or viscous media

2. Positive displacement flowmeter measures flow rate by measuring the number of times the fluid is sequentially filled and discharged in the measuring chamber, suitable for high viscosity media. Elliptical gear flowmeter: with extremely high accuracy (up to 0.2 level), suitable for measuring oil products, solvents, etc., but with large pressure loss and high requirements for cleanliness. Double rotor flowmeter: with small pressure loss, suitable for measuring large flow rates, commonly used in media such as heavy oil and asphalt. Float flowmeter (rotor flowmeter) uses the height variation of the float in a conical tube to measure flow rates, suitable for low flow and low-pressure conditions. Metal tube float flowmeter: corrosion-resistant, capable of remote signal output, suitable for scenarios such as chemical reagent addition. Glass tube float flowmeter: Low cost, intuitive and

4. Electromagnetic flowmeter is based on Faradays law of electromagnetic induction to measure the volume flow rate of conductive liquids, with no pressure loss and high accuracy (0.3-0.5 level). Must be used for media with conductivity greater than 5 μ S/cm (such as water, acid, alkaline solution), cannot measure oil or gas

5. Vortex flowmeter calculates the flow chamber wear by detecting the frequency of vortex shedding in the fluid, suitable for gases, vapors, and liquids. High temperature and high pressure resistance (up to 400 ℃/10MPa), accuracy of about 1.0 level, but afraid of vibration and high requirements for straight pipe sections

6. Ultrasonic flowmeter calculates flow rate by detecting the time difference or frequency difference of ultrasonic propagation in the fluid, non-contact measurement, and no pressure loss. External clamp type: easy to install but with low accuracy (1.5~2.5 levels), suitable for temporary measurement of large pipe diameter sensitive slag. Insertion type: High precision (1.0 level), suitable for long-term monitoring of high temperature and high pressure media

7. Coriolis mass flowmeter directly measures mass flow rate with extremely high accuracy (0.1~0.2 level), not affected by temperature and pressure density. Suitable for accurate measurement of raw material ratios and product output, but with high cost, high pressure loss, and fear of vibration. Selection should pay attention to: - Medium characteristics (viscosity, corrosiveness, solid content) - Process conditions (temperature, pressure, flow range) - Accuracy requirements and pressure loss limitations - Explosion proof rating
