instrument used to measure rainfall

1.Instrument used to measure rainfall product introduction

instrument used to measure rainfall An instrument used to measure rainfall using light sensors. It is used to measure the amount of precipitation that falls over an area over a period of time.The instrument used to measure rainfall uses a three-channel narrowband infrared detector and a pure sinusoidal AC signal source.It has the advantages of high accuracy, strong ambient light resistance, maintenance-free, and compatible with other optical sensors (light, ultraviolet radiation, total radiation).It can be widely used in meteorological, agricultural, municipal, transportation and other industries.The sensor is designed with a low power consumption and can be used in unattended observation stations in the field.

2.Instrument used to measure rainfall product features

The instrument used to measure rainfall uses a pure sinusoidal infrared light source, a built-in narrowband filter, and a rain-sensitive surface of 78 square centimeters.It can measure rainfall with high accuracy and be unaffected by high-intensity sunlight and other lights.The high light 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 No.ZL 2022 1 1306149.3)

5.Instrument used to measure rainfall precautions

1.The radius of 1 meter around the sensor level is not blocked to avoid the influence of water droplets.

2.The above sensor installation position should avoid obstruction of trees, and the oblique direction should also avoid obstruction of shade.

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