meaning of rain gauge

1.Meaning of rain gauge product introduction

meaning of rain gauge is a device for measuring rainfall, a meteorological instrument for measuring the amount of precipitation per unit area in a given time.The meaning of rain gauge uses a three-channel narrow-band infrared detector and a pure sinusoidal AC signal source.It has the advantages of high accuracy, strong resistance to ambient light, maintenance-free, and compatibility with other optical sensors (light, ultraviolet radiation, total radiation).It can be widely used Used in meteorology, agriculture, municipal administration, transportation and other industries.The sensor adopts a low-power design and can be used in unattended observation stations in the field.

2.Features of meaning of rain gauge products

The meaning of rain gauge uses a pure sine infrared light source, a built-in narrow-band filter, and a rain-sensing surface of 78 square centimeters.It can measure rainfall with high precision and is not affected by high-intensity sunlight and other light.The high transmittance rain cover does not affect direct sunlight and is compatible with other built-in optical sensors, such as light, total radiation, ultraviolet sensors, etc.(Invention patent, patent number ZL 2022 1 1306149.3)

5.Notes on meaning of rain gauge

1.There is no obstruction within a radius of 1 meter around the sensor level to avoid the impact of water droplets splashing.

2.The sensor should be installed above the location to avoid being blocked by trees, and in the tilted direction, it should also be avoided from being blocked by trees.

3.To ensure measurement accuracy, the sensor should be installed horizontally
