In the realm of fluid measurement technology, the Coriolis mass flow meter for liquid has become an indispensable tool. Astmeters is proud to offer a range of high – performance Coriolis mass flow meters designed to meet the diverse needs of various industries.
I. The Working Mechanism of Astmeters’ Coriolis Mass Flow Meter for Liquid
The Coriolis mass flow meter operates on the fundamental principle of the Coriolis effect. As liquid flows through the meter’s sensing tube, which is typically U – shaped or straight – tube in design, the Coriolis force causes a deflection of the tube. This deflection is directly related to the mass flow rate of the liquid. Mathematically, the mass flow rate (ṁ) can be expressed as ṁ = K × Δt / T, where K is a meter – specific constant, Δt is the time difference between the upstream and downstream sensor signals, and T is the oscillation period.
II. Key Features and Benefits
- High Accuracy
- Astmeters’ Coriolis mass flow meters offer an accuracy range of ±0.1% – ±0.3% of reading. For example, in the semiconductor manufacturing industry, where precise control of liquid chemicals is critical, this level of accuracy ensures the quality and consistency of the final product.
- Direct Mass Flow Measurement
- Unlike volumetric flow meters, which require density compensation, Astmeters’ Coriolis meters directly measure mass flow. This eliminates errors due to density variations, a significant advantage in applications such as food and beverage processing where the density of liquids can change with temperature and composition.
- Wide Flow Rangeability
- Our Coriolis mass flow meters can measure flow rates from as low as 0.05 g/min to as high as 800 kg/min. This wide rangeability makes them suitable for applications ranging from laboratory research to large – scale industrial production.
III. Applications in Various Industries
- Pharmaceutical Industry
- In drug manufacturing, accurate dosing of active pharmaceutical ingredients (APIs) and excipients is vital. Astmeters’ Coriolis mass flow meters ensure precise measurement, maintaining the integrity of the drug formulation.
- Chemical Processing Industry
- For the handling and processing of various chemicals, such as acids, bases, and solvents, these flow meters provide reliable measurement, contributing to process optimization and safety.
