Application of water level indicator in urban flood monitoring and alarm system

- Dec 14, 2019-

However, when cities suffered heavy storms, many cities and other places became "water cities." This not only caused difficulties for local people to travel, but also caused accidental electric shocks due to water wading. So how to avoid or prevent such incidents? It is imperative to install electricity leakage protection devices on bus stop billboards and flood control early-warning devices on electric control boxes under street lights before a rainstorm. Full-time real-time monitoring of the intrusion status of electric control boxes under street lights. Traditional equipment cannot monitor the invasion of water leakage in real time. Only regular inspection by personnel often results in losses. The pipelines of the power supply system are complex, and there are many blind spots for personnel monitoring. High-risk areas will be monitored in a focused manner; the monitoring volume will be highly sensitive to alert, and potential flooding dangers will be detected early and promptly prevented. Adopt advanced distributed and sensor technology to detect whether there is any abnormality in each part of the sensor path.


In summary, in order to better monitor the flood warning of the electric control box of street lamps, EPTSensor provides a low-cost optical water level switch / optical water level sensor-FS-IR12B solution. The sensor contains an infrared emission source and a detector, and the installation position is accurate to ensure that the two achieve good optical coupling in the air. When the tapered end of the sensor is immersed in liquid, infrared light will be transmitted out of the tapered surface, and the intensity of the light reaching the detector will be weakened. It is the best choice for urban flood monitoring alarm system.

Low-cost optical water level switch / optical water level sensor features:
(1) Fast response speed,
(2) 10mA drive current, phototransistor switch output.
(3) Working temperature: -20 ~ 65 degrees, M14 thread.
(4) Cable length is 500mm 24AWG, 8mm tinned, etc.

Low cost optical water level switch / optical water level sensor FS-IR12B Typical application:

Hot spring pool, leak detection, vending machine, food and beverage machine, medical, compressor, printer, water pump, home appliance, oil level monitoring, HVAC, machine tool, high and low level switch, water level control, automotive electronics.
