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

Is there any relationship between pressure transmitter range migration and stability?

Pressure Transmitter /

Some companies purchased pressure transmitters that allow 100-fold range migration. After migrating the transmitter range downward by 20 times, they found that the transmitter had poor stability. After restoring the standard range, no transmitter stability problem occurred. What is the reason? In this article, we will talk about the factors that cause the stability of
