With the rapid development of industrial automation technology, rotary filling systems have emerged as a key technology to enhance production efficiency and product quality. These systems are widely applied in industries like food, pharmaceuticals, and cosmetics, where high-speed, continuous production is required. However, one of the major challenges in this field is accurately and consistently […]

1. Definition and Classification of Level In industrial processes, level (liquid level, bulk solid level, and interface) is one of the four key parameters alongside temperature, pressure, and flow. It plays a critical role in production stability, efficiency, equipment safety, energy utilization, and product quality. Liquid Level (Tank/Column/Reservoir): Height of liquid surface. Bulk Solid Level

Radar level meters, which operate on the principle of electromagnetic wave reflection, are non-contact instruments designed to measure liquid levels by emitting microwave pulses and receiving their reflected signals. The process involves transmitting high-frequency pulses from the radar probe towards the surface of the liquid being measured. When these pulses encounter the liquid’s surface, they

1. Working Principle (Core Logic: Magnetic Field Interaction + Time Difference Calculation) A magnetostrictive level gauge measures liquid level based on the magnetostrictive effect. The measurement process can be summarized as follows: The electronic unit sends a current pulse into the magnetostrictive wire located inside the probe. This pulse generates a circular magnetic field along

1. Operating Conditions The water seal tank level gauge is installed in the flare system (Unit 80). It is a critical instrument for monitoring the liquid level in the water seal tank, ensuring safe operation of the flare tail gas treatment system. High level condition: When the level exceeds the setpoint, the gauge generates an

The metallurgical industry heavily relies on coke as a critical raw material, making accurate storage and management essential for maintaining production efficiency and cost control. Coke silos play a crucial role as storage facilities, ensuring a stable supply for continuous operations. This article explores the unique characteristics of coke silos, the advantages of using radar

In modern coal-fired power plants and coal chemical production, accurate level measurement is critical for ensuring continuous and efficient operations. Specifically, precise monitoring of the material level on coal mill conveyors is essential not only for maintaining the stable operation of equipment but also for enhancing production efficiency and safety. This article will discuss the

Level instruments are among the most fundamental and critical process control devices in the process industry. They act as the “eyes of the tank,” continuously monitoring level changes in storage tanks, towers, and pipelines. However, field engineers often encounter a common issue during inspections: “The tank is clearly empty, but the level gauge does not

1. Introduction In process industries, level meters are among the most fundamental and critical instruments. They serve as the “eyes” of tanks, columns, and pipelines, continuously monitoring liquid level variations. However, many engineers encounter the following issue during routine inspections: “The tank is clearly empty, but the level meter does not indicate zero!” This is

Level gauges are widely used in industrial automation to measure liquid levels in tanks and vessels. In many industries, the accuracy of level measurement directly affects production efficiency, process stability, and safety. However, in real applications, level gauge readings sometimes fluctuate, which may result in inaccurate control, equipment malfunction, or even safety hazards.This document summarizes
