Analysis of the measurement performance of radar level gauge in foam and viscous media

Level meter /

In industrial applications, accurate measurement of liquid level is essential for process control and inventory management. Radar level meters are widely used due to their non-contact measurement, high accuracy, and strong adaptability. However, when the medium is foamy and viscous, its measurement accuracy may be affected. This article aims to explore the performance of radar […]

In-depth analysis of the application of ultrasonic level meters and radar level meters in the industry

Level meter /

1. Working principle and measurement principle Ultrasonic level meter: Ultrasonic level meter measures liquid level by emitting high-frequency ultrasonic pulses and receiving echo signals reflected from the surface of the measured medium. The propagation speed of ultrasonic pulses in air (or in the medium, if calibrated) is proportional to the distance. By calculating the time

Prioritizing Reliability or Availability in Instrument Self-Diagnostic Fault Output: A Detailed Perspective

Flow meter /

In modern industrial, medical, and aerospace systems, instrument self-diagnostic fault outputs serve as a critical feature for maintaining system health. When an instrument detects a fault within itself, it sends out a warning or signal to the operator or the control system, providing valuable information for decision-making. However, when such fault warnings occur, there is
