3. Rainfall simulation experiments

The instrument has been carried out before the factory artificial precipitation simulation

precipitation test and has been based on factory inspection records produced in Figure 6 shows the

rain intensity and accuracy of the curve for the user reference. Users in the completion of indoor

installation generally do not have to manually simulate the precipitation test, you can directly use

the outdoor installation.

If the instrument is in the process of running the instrument to find the accuracy of

measurement accuracy should be carried out again artificial simulated precipitation test, re-adjust

the instrument, the method is as follows:

a test tool: a dedicated rain cylinder 1, a small dropper;

b before the test:

Before the test, remove the stainless steel outer cylinder to check whether the level of the

bubble is centered, whether the tipping is flipped flexible, no jamming phenomenon, and check

whether the waterway is smooth, and then use water to fill the mouth,

c water injection test

With two-speed drip method to test the accuracy of the instrument, the method is:

With a dedicated rainfall measuring tube to take 10mm of water, through the diversion funnel

slowly into the tipping bucket, to be tipping over the tumbling, that is to stop the water, and then

use the dropper to absorb a number of water within the tube, drop by drop into the bucket until the

tipping , Then repeat the test, record the number of tumbling reversal and consumption of water; if

the tipping over 20 times, the consumption of water 9.7 ~ 9.85mm, you can determine the
