▎ 摘　　要

NOVELTY - The device has a microcontroller unit (MCU) connected with multiple probe electrodes extending into a tank storage extinguishing agent raw liquid level. The data collected by the MCU is transmitted to a server through a wireless or limited interface. The probe electrodes are made of three titanium rods with the same size. A counter electrode, an auxiliary electrode and a working electrode are located in a same plane and parallel to each other. The working electrode is provided with a fluorinated graphene coating region. The coating region is completely extended into a surface of an extinguishing liquid. A working electrode receives a waveform signal fed back by the probe electrode through an analog-digital conversion channel (ADC) after calculating by simple integral. The server stores the data and judges whether the extinguishing fluid is currently polluted by comparing current and historical data. USE - Tank storage fire extinguishing agent pollution monitoring device for monitoring electrochemical property of water film-forming extinguishing agents and judging whether it is polluted. ADVANTAGE - The device can capture for limiting the short-term property change caused by the pollution of the extinguishing agent raw liquid, and providing a failure alarm signal. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of the tank storage extinguishing agent pollution monitoring device. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the device. (Drawing includes non-English language text).
