Target flow meters, also known as drag force flow meters, measure flow by detecting the force exerted by fluid flow on a target (or drag body) placed in the flow path. This force is proportional to the flow rate and can be translated into an accurate measurement of the flow rate for both gases and […]
Introduction Sulfuric acid (H₂SO₄) is one of the most widely used chemicals in industrial processes, ranging from fertilizer production and petroleum refining to chemical synthesis and wastewater treatment. However, its strong corrosiveness poses a critical challenge for material selection and equipment design. The corrosion behavior of stainless steels in sulfuric acid is primarily governed by

Turbine flow meters are widely used for measuring the flow rate of clean, low-viscosity fluids such as water, oil, and gas. They operate by using a rotor within the flow stream, which rotates at a speed proportional to the fluid’s velocity. This rotational speed is then translated into flow rate, making turbine meters highly accurate
Mass flow meters are crucial in various industries for measuring the mass flow rate of fluids. They are known for their high accuracy and reliability, especially in applications where measuring the actual mass of the fluid is essential, such as in chemical, pharmaceutical, and food industries. However, to ensure precise measurements, mass flow meters also
Orifice plate flow meters are widely used in industrial applications to measure fluid flow rates. Their accuracy, however, relies heavily on proper installation, particularly regarding the lengths of straight pipe required upstream and downstream. These straight sections help ensure a stable, predictable flow profile that yields accurate measurements. Below is a detailed exploration of the
Terminal blocks are critical components in electrical and electronic systems, providing secure connections for transmitting voltage, current, or signals. However, various issues can arise during their use, impacting performance and reliability. This article discusses common terminal block failures, their causes, and preventive measures. 1. Contact Failure The metallic conductor within a terminal block is the

1. Background During a recent safety inspection organized by the Municipal Emergency Management Bureau, one of the reviewing experts insisted that enterprises should add an automatic (emergency) shutdown function in the Distributed Control System (DCS) and configure a corresponding software button on the operator interface. As a participant in this inspection, I raised an objection.

Industrial automation relies heavily on robust communication protocols to ensure that devices and control systems work seamlessly together. Among the most widely adopted are Modbus TCP/IP and Profinet. While both leverage Ethernet as their physical layer, their design philosophies, performance characteristics, and application scenarios differ significantly. 1. Origins and Basic Concepts Modbus TCP/IP Originally developed
