Pressure Sensor Selection: Gauge Pressure vs. Sealed Gauge Pressure

Previously, we discussed the differences and relationships between Gauge Pressure and Absolute Pressure. Some users have noticed that when purchasing pressure transmitters, there’s also the option of choosing between sealed gauge pressure and gauge pressure. So, what is the relationship between these two, and how should we choose?

Hydrogen Flow Meters for Mass and Volume Flow

Hydrogen flow meters are widely used in hydrogen energy fields, such as hydrogen production, hydrogen storage and hydrogen fuel cells. Typically used to monitor volumetric flow, mass flow and usage of hydrogen to ensure proper system operation and optimize performance. Since the value of hydrogen is very high, custody transfer metering is also a very important feature of hydrogen flow measurement.

Sulfuric Acid Storage Tank Level Measurement

In industries such as chemical engineering, metallurgy, pharmaceuticals, electroplating, and sulfuric acid storage and transportation, sulfuric acid, as a basic raw material, is extremely corrosive. 98% concentrated sulfuric acid is viscous, fuming, and easily releases volatile acid mist. Under certain operating conditions, it is also accompanied by complex conditions such as high temperature and crystallization. Therefore, sulfuric acid storage tank level measurement places stringent requirements on the corrosion resistance, stability, and safety of the equipment. Based on our experience at S......

Case: Non-Contact Ultrasonic Flow Meter For Water

A clamp-on ultrasonic flow meter is an instrument that uses high-precision ultrasonic sensing technology to measure flow rate. It mainly consists of a host and a set of ultrasonic sensors. These sensors can be installed on the outer wall of the pipe without the pipe or shutting down the system, and they will not contaminate the medium in the pipe. The clamp-on ultrasonic flow meter measures the velocity and flow rate of fluids by utilizing the propagation characteristics of ultrasonic waves. It has advantages such as being non-invasive, highly accurate, and widely applicable. Custom Case A cli......

Top 10 Pressure Transmitter Terminology

Behind every aspect of industrial process monitoring and control lies an indispensable “invisible hero”—the pressure transmitter. The performance of a pressure transmitter determines safe operation and production efficiency. Chemical plants rely on pressure transmitters to prevent pipeline leaks, and automobile manufacturing depends on hydraulic systems for precise control of robotic arms. However, the densely packed specifications on pressure transmitter datasheets, such as “range 0-1MPa” and “accuracy ±0.1% FS,” can leave you confused about which to choose......

Top 5 Industrial Liquid Nitrogen Flow Meters

Industrial Liquid Nitrogen Flow Measurement Solution – Cryogenic Flow Measurement Design. Liquid nitrogen flow meters are a type of cryogenic flow meter specifically designed to measure the flow rate of liquefied nitrogen at extremely low temperatures (-196°C; -320°F; 77 K). Of course, similar cryogenic liquefied media can also be measured, such as LNG, LOX, LAR, and LH2. Accurate flow measurement of cryogenic fluids can optimize process flows, improve overall efficiency, and save costs. For liquid nitrogen flow measurement, Sino-Inst offers turbine flow meters, mass flow meters, gear fl......
