Introduction Level measurement plays a crucial role in the chemical industry, especially when dealing with complex and harsh conditions. Radar level gauges have emerged as an ideal solution due to their non-contact measurement capability, high precision, and excellent reliability. This article delves into the application of radar level gauges in measuring urea hydrolysis solutions, highlighting

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
