TCP (Transmission Control Protocol, Transmission Control Protocol) is a connection-based protocol. Before officially sending and receiving data, a reliable connection must be established with the other party. A TCP connection must go through three "conversations" before it can be established.
UDP (User Data Protocol) is a protocol corresponding to TCP. It is a non-connection-oriented protocol. It does not establish a connection with the other party, but sends the data packet directly.
From the above description, we can see that TCP is a reliable protocol for connection-oriented, and UDP is an unreliable protocol for connectionless. Compared with the transmission speed of the two, UDP transmission speed is higher than TCP, which is more in line with network video The monitoring system requires real-time data transmission.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
