Miniaturized, Highly Sensitive Micro-flow Metal Tube Float Flowmeter
The micro-flow metal tube float flowmeter is specially designed for measuring extremely small flows in the range of milliliters per minute (mL/min) or even liters per hour (L/h) in laboratories, analytical instruments, fine chemicals, biopharmaceuticals and other fields.
Main advantages:
Solves the problem of measuring very small flows: It can measure as low as 0.1 L/h (liquid) or 1 L/h (gas), filling a market gap.
High sensitivity and resolution: It can clearly respond to very small flow fluctuations, making it highly suitable for process monitoring and precise control.
Visual representation of very small flows: It retains the intuitive and visual advantage of float flowmeters, allowing operators to directly observe the existence and changes of very small flows, which is difficult for electronic micro-flowmeters to match.
Extremely low pressure drop: Due to the very small flow itself and optimized design, the overall pressure drop is very small, having a negligible impact on the system.
Relatively simple and reliable structure: Compared to other micro-flowmeters (such as thermal mass flow controllers), it still operates on a mechanical principle without complex electronic components, making it more reliable in certain applications.
Typical application scenarios:
Laboratory research and development: feeding of chemical reactors, catalytic research, microfluidic experiments.
Analytical instruments: flow indication of carrier gas, fuel gas, and combustion-supporting gas in gas chromatography (GC) and liquid chromatography (LC).
Biopharmaceuticals: precise measurement of trace nutrient solutions and acid-base additives in cell culture and fermentation processes.
Fine chemicals: micro-injection of expensive catalysts and measurement of additives.
Fuel cells: precise control of small flows of hydrogen and oxygen.
Semiconductor manufacturing: monitoring of small flows of special gases.
The micro-flow metal tube float flowmeter is an "observer of the microscopic world", successfully applying the macroscopic force balance principle to the almost imperceptible flow scale.
