instrument used to measure rainfall

1.Instrument used to measure rainfall Product Introduction

instrument used to measure rainfall is based on the optical scanning principle to realize real-time scanning of the size and number of raindrops, and then calculate the rainfall output.The instrument used to measure rainfall adopts three-channel narrow-band infrared detector and pure sinusoidal AC signal source.It has the advantages of high precision, strong resistance to ambient light, maintenance-free, and compatibility with other optical sensors (light, ultraviolet radiation, total radiation).It can be widely used in meteorology, agriculture, municipal administration, transportation and other industries.The sensor adopts low power consumption design and can be applied to unmanned observation stations in the field.

2.Features of instrument used to measure rainfall

The instrument used to measure rainfall uses a pure sinusoidal 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.The high-transmittance rain-sensing cover does not affect direct sunlight and is compatible with other built-in optical sensors, such as illumination, total radiation, and ultraviolet sensors.(Invention patent, patent number ZL 2022 1 1306149.3)

5.Notes on instrument used to measure rainfall

1.The sensor should be within a radius of 1 meter horizontally without any obstruction to avoid the impact of water droplets splashing

2.The sensor should be installed in a place where trees are not blocking the sensor, and the sensor should also be installed in a place where trees are not blocking the sensor.

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