A city river in Indonesia, different degrees of waterlogging occur in the rainy season every year, especially in recent years, flood control accidents are frequent, and personal safety and property safety are greatly threatened.. Therefore, the local government needs to carry out real-time monitoring of the river water level and timely alarm when the flood control limit value is reached, so that personnel can be transferred promptly and various flood control preparations can be made to minimize casualties and property losses.

1.The river has a high flow rate all year round, how to select sensors to monitor river level?

2.There are many branches and it is inconvenient to provide power supply nearby. how to provide power supply for instruments?

3.How to realize remote monitoring and alarm function of collected river water level information?

After understanding the customers’ local climate conditions, and combining withactual applications on site , we recommended customers using GUT741 ultrasonic level transmitter, and equipped with our GRT102 wireless acquisition module to resolve customers’ level monitoring problems. The customer's on-site power supply problem is solved through the solar power supply solution. GUT741 ultrasonic level transmitter can monitor river level in real time, and it is IP68, which avoids sensor damage because of being exposed to rain for a long time. The collected liquid level uploads to the cloud platform from GRT102 wireless module to realize online monitoring function of PC and APP. t the same time, the alarm threshold is set in the system, and when the alarm reaches the first level, the relevant management personnel are reminded by SMS or email and other forms to remind them to take emergency measures; When the red warning is reached, the warning horn is directly connected to remind the personnel to transfer quickly; Since the operation of the system, it has helped the local government reduce the pressure of flood control, and the program is being promoted locally.
