1. What does the flow meter parameter 1mL/min represent?

The flow meter parameter 1mL/min represents a liquid flow rate of 1 milliliter per minute. Flow meter, also known as flow meter: commonly used flow meters include electromagnetic flow meters; Vortex flowmeter; Float flowmeter; Coriolis mass flow meter; Thermal (gas) mass flow meter; Ultrasonic flowmeter; Turbine flowmeter. It is mainly used in industrial production process, energy measurement, environmental protection engineering transportation, biotechnology, scientific experiment, ocean meteorology, Rivers and Lakes and other fields.

4 methods and operating points for measuring the flue gas flow rate of a rotary kiln

1. Pitot tube measurement method • Principle: Calculate the flow rate by using the dynamic/static pressure difference, and combine it with the cross-sectional area of the pipeline to obtain the flow rate • Key parameters: Measure the cross-sectional area of the pipeline with a diameter of 4.8 meters (18.1 square meters), and the recommended distance between measuring points is 0.8-1 meters • Installation requirements: The opening position should be at least 5 times the diameter of the elbow, and the insertion depth should be 1/3 of the pipeline diameter Thermal gas mass flowmeter • Applicable conditions: flue gas temperature ≤ 650 ℃, dust content ＜ 50g/m ³ • Typical model: Sierra 780S series (range 0-50m/s, accuracy ± 1% reading) • Installation note: Vertica

l installation is required, probe length needs to match 4.8-meter pipe diameter 3 Ultrasonic flowmeter • Selection requirements: Wall thickness ≤ 50mm, recommended dual channel model (such as FLEXIM FLUXUS G721) • Measurement accuracy: ± 1.5% reading (when flow rate>1m/s) • Advantages: Can measure a wide range of flow rates from 0.01-60m/s. 4 Venturi tube • Design parameters: recommended throat diameter ratio of 0.5-0.7, pressure difference range of 500-5000Pa • Pressure loss: about 10-15% total pressure drop • Maintenance cycle: throat wear needs to be checked every 3 months Method comparison table: | Method | Accuracy | Cost | Maintenance frequency | Applicable working conditions | | ------------------------------------------------------------------------- | Pitot tube | ± 5% | Low | Monthly | Clean flue gas, temporary measurement | | Thermal flow meter | ± 1% | High | Semi annual | Low to medium dust content, requiring mass flow | Ultrasonic | ± 1.5% | Medium to high | Annual | Large pipe diameter, long-term monitoring | Venturi tube | ± 2% | Medium | Quarterly | Stable flow, allowing pressure loss | Operating advice: - Priority given to high dust Choose Venturi tube or external clamp ultrasonic - when temperature compensation is required, choose PT100 Sensor thermal flowmeter - It is recommended to set one measurement section at each inlet and outlet of the 74 meter long kiln body.
