1.What is a rain gauge used for product overview

what is a rain gauge used for What is a rain gauge used for collecting and measuring liquid precipitation in a predetermined area.This piezoelectric rain sensor uses PVDF piezoelectric film as a rain-sensing device and uses an embedded AI neural network to distinguish raindrop signals to avoid false triggering caused by interference such as gravel, dust, vibration, etc.

It is widely used in meteorological environment monitoring, hydrology and water conservancy comprehensive monitoring stations, traffic and road monitoring, agriculture and forestry, wind power generation and other relevant departments to remotely measure precipitation amount, precipitation intensity, and precipitation start and end time.It is used for automatic hydrological forecasting and reporting systems, automatic field forecasting and reporting stations, etc.for the purposes of flood control, water supply dispatching, and power station and reservoir water regime management.

2.Functional features of what is a rain gauge used for

1.Integrated design, exquisite appearance

2.No mechanical accessories, no exposed parts, can filter similar signals introduced by environmental factors such as leaves, dust, insects, etc.

3.High measurement accuracy, wide range, good stability, low power consumption, and strong ability to resist external interference

4.It can work around the clock and is not affected by weather changes, and can monitor rainfall duration accurately to the second.

5.Maintenance-free, the raindrop contact surface is an arc-shaped design structure, and no rainwater is stored.

6.With automatic horizontal calibration function after installation, no on-site calibration is required

7.Small size, easy to carry, disassemble and install

8.Made of stainless steel, high strength, anti-oxidation and anti-corrosion

6.Notes on what is a rain gauge used for

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 away from strong mechanical vibration sources.

3.There should be an open area above the sensor installation.Raindrops should fall directly to the sensor, and secondary dripping and continuous water flow impact should be avoided.
