Level meter

In industrial automation instruments, such as ultrasonic level meters and pressure transmitters, two-wire and four-wire systems are common wiring methods for signal transmission and power supply. The core differences lie in the power supply method, wiring structure, and suitability for different applications. Below is a detailed comparison of these two systems. Core Differences: A Comparative […]

Selecting a suitable non-contact level meter for wastewater is essentially about matching the instrument to the operating conditions. You can follow a simple four-step approach: Clarify conditions → Select instrument type → Verify key parameters → Avoid common mistakes 1. Identify the Three Key Selection Factors (1) Process Conditions Item What to Check Why It

Ultrasonic level meters are widely used in wastewater treatment plants, especially in scenarios where the medium is relatively simple and not highly complex. The key to selecting ultrasonic level meters for wastewater treatment tanks lies in identifying the standard conditions and the low-complexity medium. Below are the specific applicable scenarios and key considerations: I. Core

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

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
