Instrument used to measure rainfall


The instrument for measuring rainfall is a pressure gauge for measuring the pressure value generated by liquid. It can accurately judge the current pressure value generated by liquid and accurately display the pressure value. It can judge the fluid value better, faster and more accurately, so as to make accurate prediction and judgment.

A rain pressure gauge is used to measure rainfall. It typically consists of a container or funnel that collects rainwater and a measuring stick or scale to indicate the amount of rainfall in inches or millimeters. Some more advanced rain gauges may also have electronic sensors to transmit data to a computer or weather station.

Pressure is expressed in two ways: one is the absolute vacuum as the basis of the pressure, known as the absolute pressure;The other is the pressure represented by atmospheric pressure as a benchmark, known as the relative pressure.Relative pressure is also called gauge pressure because the pressure measured by most manometric instruments is relative.When the absolute pressure is less than atmospheric pressure, it can be expressed as the absolute pressure in the container is less than one atmosphere.This is called "vacuum degree".
