如何確保天然氣流量計準確度性

Issuing time:2019-01-08 09:17

隨著天然氣產業的大發展,天然氣流量計工作也獲得了越來越多的重視,我國已經在天然氣流量儀表的設計選型、使用、安裝、維護、管理和氣質分析等方面取得了一些成果。

無錫歐百儀表科技有限公司是無錫高新技術企業。公司以先進制造業為主,集儀器儀表設計開發、生產;工業自動化;節能環保;校企創新為一體的多元化、現代化企業。下面小編給大家淺析一下如何確保天然氣流量計準確度性:

1、定期清洗檢查孔板。比如孔板光潔度、直角邊銳利度、膠圈變形情況、孔板開孔直徑等。在正常的生產情況下,每月清洗檢查一次,在出現不正常的情況下,視情況加密檢查次數。

2、對流量計前過濾器每兩小時排污一次,每月清洗過濾器芯一次。

3、正確輸入計量參數并及時更新,按時校驗變送器零點。另外,在氣量波動較大的情況下,及時調節差壓變送器量程,使測量值盡量在量程的1/3~2/3之間,以保證測量準確度。在測量值超出變送器最大、最小量程范圍時,要考慮更換合適孔徑的孔板。
