流量計設置零點
Flowmeter Setting Zero Point
注:(流量計安裝後必須先進置零操作)
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,在流量計安🏃🏻♀️裝💔時不在水平方位
狀況下,需要重新設置流量計零點。操作程序爲:(也💁🏼♀️可在👱🏼♂️管道内👩🏼❤️👨🏾無介質流動時直接置零,高溫型及低👩🏽🐰👩🏿溫型流量計必須使管道内溫度達到工作溫度後👩🏿❤️💋👨🏽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、關閉流量計下遊的閥門;
A. Close the valve downstream of the flowmeter;
b、緩慢打開流量計上遊閥門,使流量計充滿介質;
B. Slowly open the upstream valve of the flowmeter to fill the flowmeter with medium.
c、緩慢打開流量計下遊閥門,使流量計運行10分鍾左右;
C. Slowly open the downstream valve of the flowmeter to make the flowmeter run for about 10 minutes.
d、關閉流量計上、下遊閥門,并确定管道内流量爲零;
D. Close the upstream and downstream valves of the flowmeter and determine that the flow in the pipeline is zero.
e、用手指按在“<”位置不小于3S:
E. Put your finger at position'<'not less than 3S:

質量流量計直接測量通過流量計的介質的質量🤶🏾流量,還可測量介質的密度及間接測量介質的溫度。由于變送器是以單片機爲核心的智能儀表,因此可根據上述三個基本量而導出多種參數供用😘戶使用。 質量流量計組态靈活🧛🏽,功能強大,性能價格比高,是新一🧎🏻♀️➡️代流量儀表。
