Level meter

Asphalt storage tanks present unique challenges for level measurement due to their high temperatures (130-230°C), high viscosity, tendency to adhere to surfaces, and volatile compounds. Therefore, the key principles for selecting a measurement method are “non-contact, high temperature tolerance, and resistance to interference.” Based on adaptability, stability, and maintenance cost, the guided wave radar level […]

1. Working Principle and Structure of Radar Level Meters A radar level meter consists of several key components: a transmitter and receiver, signal processing unit, antenna, and display system. The operating principle involves the emission, reflection, and reception of electromagnetic waves. The antenna sends out radar waves, which are reflected by the surface of the

With the advancement of industrial automation and intelligence, non-contact measurement technologies have become increasingly prominent in addressing challenges posed by complex industrial environments. Among these technologies, radar level meters stand out due to their high efficiency, precision, and reliability, becoming the mainstream choice for level measurement. This article explores the application of radar level meters

In process control systems, buffer tank level control (LIC) is typically considered a “slow-variable” control loop. Usually, a level controller stabilizes the level by cascade controlling the feed flow rate (FIC1). However, when a second feed flow rate controller (FIC2) is added to the system, new challenges arise: How should control authority be distributed between

Level indicators, used for monitoring the liquid levels in tanks and vessels, play a crucial role in industries such as petrochemical, food and pharmaceuticals, hydropower, and storage management. The accuracy of their measurements directly impacts production safety, process control, trade settlement, and inventory management. Therefore, regular calibration and testing of level indicators is essential for

1. No Display / Instrument Not Starting Possible Causes: Power interruption (power module failure, disconnected wiring) Internal fuse blown Mainboard failure Maintenance Steps: Use a multimeter to check the power lines, repair any disconnections, or replace the faulty power module. Open the instrument and inspect the fuse (usually near the power connection); replace it with

Magnetostrictive level transmitters use the magnetostrictive effect (where a magnetic field causes a metal rod to undergo elastic deformation and generate ultrasonic waves) to provide highly accurate level measurements. The key advantages are non-contact measurement, high precision (typically ±0.1%), and excellent stability. These devices are widely used for level monitoring in closed or open containers

Abstract Precise monitoring of dust hopper levels in electrostatic precipitators (ESPs) plays a critical role in ensuring the stable operation of thermal power plants, preventing equipment failures, and achieving environmental protection goals. This article discusses the working principles, advantages, and practical applications of radar level meters in this context, with a focus on their performance
