1. There is a flow meter with 485 wire that supports Modbus protocol, and I want to remotely transmit the flow and pressure to the companys electrical system ..

With 485 output, wireless transmission can be achieved in one RTU, allowing for data viewing on mobile phones and computers, fault reminders, map location display, and more.

2. How do gas companies control gas meters

1. Wireless remote transmission meters can achieve remote grinding and control, thanks to the support of handheld devices or data terminals.

2、 Wired remote meters are centrally read and controlled through computers and their supporting software.

3、 The network remote transmission meter utilizes contemporary network technology for remote monitoring.

4、 The upcoming IoT controlled gas meter represents the latest development of blind spine calling technology. Gas meters, also known as flow meters, are a type of measuring equipment that must be calibrated in accordance with national mandatory calibration regulations.

3. Remote transmission principle of metal tube float flowmeter

The core of the remote transmission principle of metal tube float flowmeter is to convert the axial displacement of the float that changes with the fluid flow rate into remotely transmitted electrical or digital signals, realizing the collection and transmission of flow data off-site.

1. Core components of remote transmission system (1) Non contact displacement detection unit 1 The mainstream use of magnetic coupling detection scheme: permanent magnetic steel is embedded inside the float, and the metal measuring tube is made of non-magnetic stainless steel material. When the fluid thrust is bal

anced with the gravity and buoyancy of the float, the float moves axially along the conical measuring tube, and the spatial position of the magnetic steel inside the float changes synchronously with the flow rate. Hall sensors and giant magnetoresistance sensor arrays installed on the outside of the measuring tube sense the magnetic field changes of the magnetic steel, convert the float displacement into continuous electrical signals, and do not need to penetrate the measuring tube to avoid the risk of medium leakage. Some scenarios also use capacitive and inductive detection schemes, which require signal transmission through insulation bushings or openings, with slightly lower adaptability than magnetic coupling schemes. （2） Xinzhao bending number conversion unit 1 Perform amplification, filtering, and linear calibration on the detected displacement electrical signals, and convert the displacement into corresponding flow values. Output standardized remote transmission signals: common types include 4-20mA analog signals, HART protocol digital signals, Modbus RTU bus signals, and some products support pulse output for flow accumulation measurement. New wireless remote transmission products have built-in communication modules that can directly output wireless transmission signals such as LoRa and 4G. （3） Signal transmission unit 1 Wired transmission connects standardized signals to secondary instruments, DCS systems, or PLC systems in the control room through shielded cables that meet industrial protection levels. Wireless transmission uploads traffic data to the cloud or remote monitoring terminals through built-in wireless communication modules, suitable for wireless or mobile monitoring scenarios without wiring.
