3 Details of the device

The rain gauge is one of the important instruments in hydrological equipment. HY. JFZ-1 “Float type capacitive rain gauge” detects the rainfall through the capacitive displacement sensor and converts the rainfall into a digital signal and then processed by a microcomputer. Convert to pulse output.

4 main performance characteristics

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.

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.

Good compatibility: The output of the rain gauge is a pulse, and it is a passive (power isolation) form, so it can be matched with any manufacturer's collecting instrument used in a domestic hydrological automatic station or a single rainfall station and can directly replace the old-style. The tipping bucket rain gauge.

Easy maintenance: The internal structure of the rain gauge is modular and integrated. No additional tests and adjustments are required during installation. After fixing, connect the cable and turn on the power to begin measurement. Therefore, on-site installation and future maintenance are very simple. This is unique compared to previous installations and maintenance of rain gauges.
