How to adjust the liquid level using a linkage float level switch?

Stable and accurate inlet gas flow monitoring is the core prerequisite for efficient and safe operation of water electrolysis hydrogen production equipment. The inlet raw gas of electrolytic hydrogen production features low viscosity, high cleanliness and mild operating pressure, putting forward specific requirements for flow measurement instruments. As a high-precision, fast-response speed-type measuring device, gas turbine flow meters are gradually applied in hydrogen production inlet pipeline monitoring.

Turbine flow meters are widely recognized for their high accuracy, excellent repeatability and fast dynamic response, making them mainstream equipment for industrial fluid custody transfer and precise process metering. However, their core rotating impeller and precision bearing structure determines strict limitations in medium adaptability. Blind application in inappropriate working conditions easily causes bearing abrasion, impeller deformation, signal failure and rapid performance attenuation

Vortex flow meters rely on bluff body probes to generate regular Karman vortex streets, making probe surface condition the key to stable and accurate flow measurement. In industrial scenarios such as chemical production, sewage treatment, steam pipelines and brine transportation, probes are prone to scaling, adhesive fouling and electrochemical corrosion after long-term operation. Damaged probe surfaces disrupt vortex generation, cause signal jitter, measurement deviation and even meter failure.

A widespread misconception in the industrial instrumentation industry claims that vortex flow meters operate accurately without temperature and pressure compensation. This simplified but misleading statement has misled numerous purchasers and engineering teams into improper configuration, resulting in severe measurement deviations, inaccurate energy statistics and unqualified custody transfer data.
