Industrial pipelines in thermal power, petrochemical, and heavy manufacturing industries commonly suffer from strong mechanical vibration caused by large-scale equipment operation, fluid impact, and pipeline resonance. Conventional vortex flow meters are highly susceptible to external vibration interference, resulting in signal jitter, flow data fluctuation, and reduced measurement accuracy under such harsh conditions.

Vortex flow meters are widely utilized for measuring gas, liquid, and steam flow in industrial process control due to their simple structure, zero moving parts, and stable long-term performance. However, flow rate fluctuation is one of the most common operational faults during field application, which leads to unstable measurement data, reduced metering accuracy, and even interference with automatic process control systems. Flow fluctuations are mainly caused by abnormal fluid flow fields, non-standard installation, sensor failures, medium condition changes and external environmental interference.

Vortex flow meters rely on the stable Karman vortex street generated by fluid turbulence to realize flow measurement, and the uniformity and stability of pipeline fluid flow field are the key guarantees for measurement accuracy. Straight pipe section installation is the most critical basic installation condition for vortex flow meters, as irregular pipe fittings such as elbows, valves and reducers will cause fluid turbulence, velocity deviation and swirling flow, destroying the regular vortex shedding state.

Vortex flow meters are widely used for steam flow measurement in industrial thermal systems, chemical production and power industries. However, steam belongs to a compressible gas medium, and its density changes significantly with real-time temperature and pressure fluctuations. Direct volume flow measurement by vortex meters cannot reflect the actual mass flow, resulting in large metering errors.

Vortex flow meters and turbine flow meters are two of the most widely used velocity-based flow measuring devices in industrial process systems, serving accurate flow monitoring for gas, liquid, and steam media. Although both instruments calculate flow rate based on fluid velocity, they differ significantly in working principles, structural design, measurement performance, environmental adaptability, and maintenance requirements.

Vortex flow meters are widely adopted velocity-type flow measuring instruments in modern industrial process control, applicable to the flow measurement of gas, liquid, and steam media. Featuring simple structure, high measurement accuracy, strong stability, and no mechanical moving parts, they have become core measuring equipment in petrochemical, power, environmental protection, and pharmaceutical industries.

Differential pressure transmitter positive and negative pressure tap installation specifications to avoid liquid accumulation in the pressure taps and errors.

Boiler furnace negative pressure is a critical parameter for ensuring the safe, stable and efficient operation of thermal power and industrial boiler systems. The negative pressure transmitter serves as the core monitoring device, whose installation quality and commissioning accuracy directly determine the authenticity of operating data and the safety of boiler combustion. Improper installation is likely to cause air leakage, signal attenuation and vibration interference, while non-standard commissioning will lead to measurement deviation and false alarm faults.

Differential pressure transmitters are core measurement devices widely used in industrial process control, with measurement accuracy, service life and operational stability highly dependent on the compatibility with measured media. Wastewater, steam and high-purity gases are three typical industrial media with distinct physical and chemical properties, which put forward completely different requirements for transmitter structure, material and technical parameters.
