WATER-METER CALIBTRATING DEVICE
This type of
device was manufactured by Beijing Tap-water company（water-meter
factory）which
was the only one could do that at that time in China. The device was made in the 80’s and used till 2010 which used for
calibtrating water meters by the static volume method. The device used for calibtrating water meters by
the static volume method.
The device was used for calibtrating the numerical fault of
water meters by the static volume method.
The device was manufactured under the national standard , the
national inspection procedure of the water-meter and the tester by the branch
of (named water-meter factory) Beijing Tap-water company (now is Jingzhao
water-meter CO.LTD. ) in the 80’s and used till 2010 .
Ozone
generator
In china ,Tian
cunshan purification water factory which is the first one to use the advanced
treatment technology of ozone-activated carbon adsorption process during the
1985-2007. The ozone generator was imported from japan which used for producing
ozone.
The technology
of the device/equipment is ,after dried and dehumidificated , the clean air was
imposing on high voltage by the two opposing electrodes , then the oxygen came
to be ozone under the gaoyafangdian .
The ozone can
clean , sterilizate , oxidate organicmatter ,removale DOC and so on .
