Fluid Level Measurement in Production Storage Vessels

Storage vessels are the key equipment in industrial production for holding raw materials, intermediates and finished products. Widely distributed across various process stages, they perform buffering, storage and blending functions. As basic vessel instrumentation, level measurement devices provi... Read More

Common Misconceptions in Routine Instrument Maintenance in Chemical Industry (Part II)

In the operation of chemical plants, on-site measurement instruments—such as level gauges and temperature sensors—serve as the front-line terminals for acquiring process variables, continuously collecting and monitoring core parameters like temperature, liquid level, pressure and flow rate. The m... Read More

Common Misconceptions in Routine Instrument Maintenance in Chemical Industry (Part I)

In chemical production, measuring instruments such as pressure transmitters and flowmeters act as the “eyes” that monitor the production schedule, constantly keeping track of key process parameters like pressure, level, temperature and flow. The stability and accuracy of their operati... Read More

3-Valve or 5-Valve: How to Choose Manifold for Differential Pressure Transmitter?

In industrial process measurement, differential pressure transmitters are responsible for detecting critical parameters such as pressure difference, liquid level and flow. A DP transmitter measures the pressure difference between two points and its sensing element (the diaphragm capsule) is delic...

How can Pressure Measurement Benefit from Capillary Tubing

A diaphragm seal separates the process medium from the pressure measuring instrument, thereby protecting both from each other. These barriers are essential when the medium is aggressive and would damage the pressure transmitter, as well as to prevent the contamination of hygienic media. In most a... Read More

Wangyuan: 20 Years of Process Measurement Empowering Industry

Located at Suide Road in Shanghai Putuo, a seemingly low-profile yet technologically formidable enterprise has been quietly cultivating its expertise for over two decades. With a solid portfolio of technology patents and orders from major national projects, it has raised its flag in the field of ... Read More

How to Utilize Pressure Measurement Data?

Pressure transmitters are often designed for data collection in industrial field applications, capable of outputting standardized signals and providing control systems with stable, reliable measurement data. From the perspective of measurement principles, the pressure of the measured medium is no...

Electromagnetic Flowmeter: The Preferred Choice for Dirty/Corrosive Media

In industrial sectors such as chemical, metallurgy, wastewater treatment, paper and and mining, the objects of flow measurement often present complex characteristics including solid-contenting corrosive or viscous. Common flow measuring instruments like orifice plate or vortex flowmeters generall... Read More

How to Select Appropriate Diaphragm for Pressure Transmitter？

As the core sensing devices in industrial automation control systems, pressure transmitters frequently encounter harsh measurement environments in modern process industries such as petroleum, chemical, power, food, and pharmaceuticals. Its sensor diaphragm is not only the sensing element for pres...

What are the Key Factors for Applying Vortex Flowmeters?

Vortex flowmeters operate based on the Kármán vortex street principle. Due to their features such as high accuracy, wide turndown ratio, and no moving parts, vortex flowmeters are widely used in steam, gas, and liquid flow measurement. However, these instruments are extremely sensitive to fluid f... Read More

When to Use Absolute Pressure Transmitter?

Pressure measurement and monitoring is an essential part of modern industrial processes. The pressure to be measured can be defined as different categories based on measurement reference. While measuring gauge pressure can be sufficient for most industrial applications, sometimes use an instrumen... Read More

When is Integrated Temperature-pressure Compensation Necessary for Vortex Flowmeters?

A vortex flowmeter is a flow measurement instrument designed based on the “Kármán vortex street” phenomenon. When fluid flows past a bluff body (vortex shedder) inside the pipeline, alternating rows of vortices are generated on both sides. By detecting the vortex frequency with a sens... Read More
