1. What is Modbus RTU Modbus RTU (Remote Terminal Unit) is a variant of the Modbus communication protocol used for serial communication. It is a common industrial control system communication protocol, usually used to collect sensor data, control actuators, and monitor device status. Modbus RTU uses binary encoding and uses serial communication protocols (such as […]

Foreword The natural gas ultrasonic flow meter is an instrument that uses the characteristics of ultrasonic waves propagating in gas to measure gas flow. This flow meter is widely used in the field of natural gas. Its working principle and characteristics are as follows: Operating Principle The natural gas ultrasonic flowmeter measures gas flow by

1. Introduction: RS-485 is a standard protocol for transmitting data. It can be used to establish a reliable, high-speed, real-time, multi-node data communication network connection. RS-485 is also called TIA-485. RS-485 is a standard that defines the electrical characteristics of drivers and receivers used in serial communication systems. RS485 is widely used in industrial control

Basic Components The working principle of explosion-proof electromagnetic flowmeter is mainly based on Faraday’s law of electromagnetic induction. The explosion-proof electromagnetic flowmeter consists of two parts: a sensor and a converter. The sensor is installed on the measuring pipe to detect the induced electromotive force generated when the fluid flows; the converter is responsible for

Why use Modbus acquisition module? The Modbus acquisition module is widely used because it provides a standardized communication protocol to ensure compatibility between different devices. It supports multiple communication methods, is easy to implement, and can adapt to different network environments. The Modbus module can collect and transmit various industrial data, such as temperature, pressure,
