Thermal Dispersion Flow Switches: A Complete Guide

A thermal diffusion flow switch is a flow monitoring device based on the principle of thermal diffusion. It offers superior performance and reliability. Thermal diffusion flow switches have no moving parts. They are durable, have low maintenance costs, and are highly reliable. We, Sino-inst, offer the SI-300C and SI-600 series of thermal diffusion flow switches. They can output PNP, NPN, relay, and normally open + normally closed (SPDT) signals. This article will provide a detailed overview of thermal diffusion flow switches. RFQ Table of ContentsWhat is thermal dispersion?What is a thermal di......

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......

Liquid Nitrogen Cryogenic Tank Level Monitoring

When using liquid nitrogen tanks, it’s crucial to constantly monitor the liquid nitrogen level inside. Replenishing the tank as needed ensures the sample remains at a constant -196°C, preserving its activity. Generally, replenishment is necessary when the level drops below one-third. Insufficient liquid nitrogen will prevent complete coverage of the sample, causing the internal temperature to rise and ultimately damage the sample. However, liquid nitrogen tanks are not transparent, making it impossible to directly observe the internal liquid level. Even with the lid open, the cryogenic l......

Lime Slurry Flow Measurement – Electromagnetic Flow Meter

An electromagnetic flow meter is an instrument that measures the flow rate of conductive fluids by utilizing the induced voltage generated by the fluid. Because electromagnetic flow meters are designed not to introduce protrusions or obstructions in the pipeline, they are suitable for a wide range of applications, from clean liquids to slurries and highly corrosive or abrasive fluids. Case Study A customer from Australia wanted to measure the flow rate of a lime slurry containing 25% calcium oxide. However, the slurry flow rate was very low, and the customer’s pipeline was a little large......
