Introduction Guided Wave Radar (GWR) transmitters rely on waveguides to direct the propagation of electromagnetic pulses into the measured medium. The choice of waveguide type has a significant impact on signal quality, measurement accuracy, installation feasibility, and maintenance effort. This document introduces the three common waveguide types—rigid rod, flexible cable, and coaxial tube—and provides selection […]

1. Background In steam turbine operation, condenser hotwell water level is a critical parameter. A stable level ensures: Reliable condensate pump operation without cavitation. Adequate condenser cooling area to maintain vacuum efficiency. If the hotwell level is too low, condensate pumps may cavitate. If it is too high, condenser vacuum deteriorates, leading to unsafe turbine

Introduction In industrial production, flash tanks are essential equipment used to rapidly heat liquids to boiling, effectively separating steam from liquid. Precise measurement of liquid levels in flash tanks is crucial for maintaining process stability and ensuring operational safety. The magnetic level indicator (MLI) is widely used in this context due to its high reliability

Abstract Radar level transmitters are widely used in chemical storage tanks, wastewater basins, and bulk solids silos. However, many engineers complain about unstable readings, false alarms, or persistent measurement errors. This article explains the underlying principles, highlights common mistakes, and provides practical guidelines to ensure accurate radar level measurement in real-world applications. 1. Working Principle

Abstract Level measurement is a critical element of industrial process control, directly affecting production safety, reliability, and efficiency. Commonly used instruments include radar level transmitters, ultrasonic level meters, tuning fork level switches, magnetic level indicators, and float-type gauges. Each technology has unique installation requirements; neglecting them can cause inaccurate readings, false signals, or equipment failure.

Abstract In radar level measurement, users are often confused between normal-temperature and high-temperature radar level transmitters. The key difference lies in temperature resistance and structural design. This article explains their distinctions, common working principles, and typical application scenarios, providing a quick selection guide for engineers. 1. Core Differences 1.1 Temperature Resistance Normal-Temperature Radar Level Transmitter:Designed

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
