Flow Meter

Electrode: Its function is to extract and induce a proportional induced inductive potential signal. The electrodes are typically made of non-magnetically conductive stainless steel and are required to be flush with the liner so that the fluid passes unimpeded. It should be installed in the vertical direction of the pipe to prevent deposits from accumulating on it and affecting the measurement accuracy.
Enclosure: Made of ferromagnetic material, it is the cover of the distribution system excitation coil and isolates the interference of external magnetic field.
Lining: A complete electrical insulation lining on the inside of the measuring tube and on the flange sealing surface. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring catheter and prevent the induced potential from being short-circuited by the metal measuring tube wall. Most of the lining materials are PTFE plastics and ceramics that are resistant to corrosion, high temperature and wear.
Converter: The induced potential signal generated by the liquid flow is very weak and is greatly affected by various interference factors. The function of the converter is to amplify and convert the induced potential signal into a unified standard signal and suppress the main interference signal. Its task is to amplify the induced potential signal Ex detected by the electrode into a unified standard DC signal.

Intelligent GPRS MAG flow meter working principle
Since the GPRS communication is a data packet communication network based on an IP address, after the monitoring center computer logs in to the Internet network, the IP address is assigned by the Internet, and each GPRS monitoring point establishes a connection with the host through the address and communicates. Each monitoring point collects data through the data acquisition module, processes the data through the embedded processor in the GPRS terminal, encapsulates the protocol, sends it to the GPRS network, and transmits it to the user data monitoring center computer.
Battery-powered converter GPRS communication introduction
The battery-powered converter with GPRS function can directly send data to the remote control center through the GPRS wireless module GPRS-DY or GPRS-DF, hereinafter referred to as the GPRS module, and then store the collected data in the database at regular intervals. Through the system, even in an off-site away from the observation site, it is convenient to collect and read data of each monitoring point, and truly realize the functions of remote monitoring and data sharing.
