By Li Rui, Senior Process Engineer at Sino-Inst | Published 2026-03-24. If you’ve ever had an ultrasonic level sensor fail prematurely, there’s a good chance the probe material was wrong for the job. I’ve seen this happen more times than I’d like to admit — a perfectly good sensor, installed in a sulfuric acid tank, … Read more
Flush diaphragm pressure sensors engineered for tunnel boring machines. Measures earth pressure, grouting pressure and slurry in EPB shields — built to replace imported brands at a fraction of the cost. Key Features－Engineered for the Harshest Underground Conditions Tunnel boring machines operate in extreme environments — abrasive soil, corrosive slurry, constant vibration and high pressure. … Read more
The 3D Level Scanner for Silos utilizes millimeter-wave penetration technology, enabling stable operation in complex environments with high dust and humidity, accurately sensing the surface morphology of material piles. Traditional single-point radar level meters often cannot handle complex conditions such as the “angle of repose,” “material adhesion,” and significant material level differences formed by solid … Read more
When purchasing pressure transmitters or flow meters, the sales engineer will usually confirm with you what IP rating you need: IP65, IP67, or IP68? This explanation aims to help you understand the details of IP ratings. Next time you purchase electrical equipment, you’ll know which IP rating to choose. What is an IP rating? First, … Read more
What is Absolute Pressure Transmitter? Absolute pressure transmitters are sensors that measure pressure using absolute vacuum (0 bar) as a reference. They convert the sensed physical pressure value into a standardized electrical signal, such as 4-20 mA or 0-10 V, for processing by control systems or monitoring equipment. They are often called “industrial barometers” or … Read more
In gas flow measurement and control, it is crucial to distinguish between Normal Conditions and Standard Conditions. This is primarily because the volume of gas changes with temperature and pressure. Different standards will result in different measured gas values. This is somewhat similar to the difference between “SCFM (Standard CFM) and ACFM (Actual CFM)“. Characteristics … Read more
SCFM (Standard CFM) and ACFM (Actual CFM) are commonly used units for measuring gas flow rate. For example, in the air compressor industry, they are used to measure airflow and air consumption. So what are the differences between them? How should they be converted? Both SCFM and ACFM are based on CFM. CFM is a … Read more
Thermal Mass Flow Meters and thermal mass flow controllers are suitable for most gaseous media. If a gas mass flow controller or thermal mass flow meter is factory-calibrated for one gas, but you want to switch to another, then a gas correction factor (GCF) is needed. What is Thermal Mass Flow Meter Correction Factor? The … Read more
The high pressure mass flow controller/flow meter is designed for high-pressure applications, measuring or controlling the flow rate of high-pressure gases. It features good pressure resistance, suitable for applications above 20MPa, and can be customized for 20-60MPa. For example, it is suitable for high-pressure hydrogen refueling units in the hydrogen energy industry. Features Featured Parameters … Read more
The Compact Vortex Shedding Flow Meter is a flow sensor based on the “Karman vortex street” principle. It features a compact structure, lightweight design, and better price. It can be installed on various devices. It can be used not only for measuring the flow rate of common liquids such as water and oil, but also … Read more
