Electromagnetic flow meters are widely used for conductive liquid measurement, but negative pressure (vacuum) conditions introduce serious technical risks. In most cases, standard electromagnetic flow meters are not suitable for negative pressure applications.
However, specially designed electromagnetic flow meters with F46 (FEP) or PFA linings can operate under limited, controlled negative pressure, provided strict technical conditions are met.

Air quality flow meters play a critical role in environmental monitoring, laboratory testing, and industrial air measurement. However, one common operational issue users encounter is restricted or poor air outlet flow, which can directly affect measurement accuracy and equipment reliability.

Electromagnetic flow meters play a critical role in industrial automation and process control, particularly for measuring conductive liquids in water treatment, chemical processing, food and beverage, and energy industries. Choosing a reliable brand directly affects measurement accuracy, operational stability, and long-term maintenance cost.

Thermal gas mass flow meters are among the most effective instruments for measuring gas flow in modern industrial applications. Unlike traditional flow meters, they directly measure mass flow without requiring temperature or pressure compensation. Thanks to their advanced operating principle and wide measuring range, thermal mass flow meters are increasingly replacing differential pressure and vortex flow meters in many industries.

Selecting a gas mass flow meter is more than picking a model with the right price. Gas measurement is inherently complex due to variations in temperature, press

Gas turbine flow meters are widely used across industrial applications due to their high accuracy, wide turndown ratio, and excellent repeatability. However, like any precision instrument, they may encounter various issues during long-term operation. This guide provides a practical “symptom → cause → solution” breakdown to help users diagnose and resolve common problems quickly and effectively.

Electromagnetic flowmeters are widely used in water treatment, chemical processing, energy management, and trade settlement. Ensuring their accuracy through proper calibration is essential for reliable measurement and stable process control. This guide offers a clear, step-by-step overview—from basic concepts to advanced calibration techniques—to help technicians, engineers, and metrology professionals achieve precise and trustworthy results.
