▋ Measurement Method
The electronic water gauge measures the water level height of river, irrigation area and underpass in real time through the induction contact principle, and reports it to the cloud server through 4G/NB-IoT and other communication methods, providing data support for the command and decision-making of industry users, and improving the hydrological measurement capability.

▋ Installation Method

The Wall-mounted vertical installation is often used in the measurement scenarios of road water, culvert water, reservoir, river and lake.

The Wall-mounted inclined installation is often used in agricultural channels, irrigation channels, DAMS and other measurement scenarios

▋ Application

BOY-SW02-LR electronic water gauge can measure water level by means of inductive contact measurement principle, built-in data transmission unit and lithium battery, which solves the complicated problems of urban construction. It is suitable for the real-time water level measurement of the lower interchange water, reservoir, river lake, agricultural canal irrigation canal and other scenarios.
▋ FAQ

1. electronic measuring principle?

The electronic water gauge uses inductive contacts to measure the water level data of the electrode through the Microsoft conductivity principle of water.

2. electronic water gauge measuring range?

Electronic water gauges measure ranges from 0.8-4 meters. Range for 0.8/1.2/1.6/2.0/4.0/2.4/3.2 meters are optional.

3. Does the integrated electronic water gauge need an external communication module?

No need. The integrated electronic gauge is an integrated design that includes communication modules and batteries. It can report to the server through the built-in 4G full netcom module.

4. How long does the integrated electronic water gauge send data?

By default, the integrated water meter collects data at an interval of 15 minutes and sends data to the server at an interval of 1 hour. You can adjust the sending interval as required.

5. How long can the integrated electronic water gauge supply power? Do you need an external power supply?

The integrated electronic water gauge has a built-in 20Ah battery, which can be charged by mains power and solar energy (3W solar panel is standard). By default, it can work continuously for 5 months under cloudy and rainy conditions.
