Overview
The capacitive rain gauge is one of the important instruments in the hydrological test equipment. It detects the rainfall through the capacitive displacement sensor. Since the resolution of the capacitive sensor is 0.01, the measurement of the capacitive gravimeter is very accurate. The upper and lower electric valves are used to control the influent and drainage, which in turn makes the rain gauge of the capacitance gauge not lose during the recording of precipitation, thus ensuring the accuracy of the measurement process.
Main performance features
1. High precision: Since the precision displacement sensor is used, its resolution is 0.01, so the detection accuracy of rainfall can reach 0.01, and it can also accurately measure 0.1 mm rainfall. 2. Accurate measurement: The rainwater in the upper rain-loader enters the float chamber and the rainwater in the float chamber is discharged. Two electric valves are used for automatic control. Even if there are heavy rainstorms, there will not be any loss of rainfall. This kind of scientific design fundamentally solves the problems inherent in the measurement errors of siphons or dumping rain gauges in the event of heavy rainfall.
3. Good compatibility: The output of the rain gauge is a pulse, and it is a passive (power isolation) form. Therefore, for any domestic manufacturer of the hydrological automatic station or single rain station, it can be matched and can be directly Replace the old tipping bucket gauge.
4. Easy maintenance: The internal structure of the rain gauge is modular and strong. No additional tests or adjustments are required during installation. After fixing, the cable is connected and the power is turned on. Therefore, on-site installation and future maintenance are very simple. This is unique compared to previous installations and maintenance of rain gauges.
