流量計(jì)設(shè)置零點(diǎn)
Flowmeter Setting Zero Point
注:(流量計(jì)安裝后必須先進(jìn)置零操作)
Note: (Flowmeter must be set to zero first after installation)
由于電容式力傳感器及阻流件有自重,在流量計(jì)安裝時(shí)不在水平方位
狀況下,需要重新設(shè)置流量計(jì)零點(diǎn)。操作程序?yàn)椋海ㄒ部稍诠艿纼?nèi)無(wú)介質(zhì)流動(dòng)時(shí)直接置零,高溫型及低溫型流量計(jì)必須使管道內(nèi)溫度達(dá)到工作溫度后置零)
Because of the self-weight of capacitive force transducer and blocker, it is not in horizontal position when flowmeter is installed.
In this case, it is necessary to reset the zero of the flowmeter. Operating procedures are as follows: (also can be placed directly in the pipeline without medium flow, high-temperature and low-temperature flowmeters must make the temperature in the pipeline reach zero after working temperature)
a、關(guān)閉流量計(jì)下游的閥門(mén);
A. Close the valve downstream of the flowmeter;
b、緩慢打開(kāi)流量計(jì)上游閥門(mén),使流量計(jì)充滿介質(zhì);
B. Slowly open the upstream valve of the flowmeter to fill the flowmeter with medium.
c、緩慢打開(kāi)流量計(jì)下游閥門(mén),使流量計(jì)運(yùn)行10分鐘左右;
C. Slowly open the downstream valve of the flowmeter to make the flowmeter run for about 10 minutes.
d、關(guān)閉流量計(jì)上、下游閥門(mén),并確定管道內(nèi)流量為零;
D. Close the upstream and downstream valves of the flowmeter and determine that the flow in the pipeline is zero.
