VICKERS威格士齒輪泵4520V66A4-1DB22R高低壓變量葉片泵
一般情況下，變送器零位調整只是對系統有一個零位的偏移量，但對量程的調整會對零點有1/4的影響。，某儀表廠生產的輸出為（4～2）mA的變送器，若零點（4mA）已調好，在滿量程時輸出為2.1mA,則調整滿度旋鈕，調整量為（2.1-2.）1/4=.25mA，使滿量程輸出為（2.-.25）=19.975mA。卸壓后零點輸出大概為3.975mA，調整零點至4.mA，再加壓至滿量程調整。
ASW-4在線熒光法溶解氧分析儀采用熒光法替代傳統的膜式電極，不用更換膜片和電解液，從而減少了維護工作量，提高了工作可靠性，特別適用于污水處理領域惡的工況。熒光法溶解氧儀是基于物理學中特定物質對活性熒光的猝熄原理，傳感器前端的熒光物質是特殊的鉑金屬卟啉復合了允許氣體子通過的聚酯箔片，表面涂了一層黑色的隔光材料以避免日光和水中其它熒光物質的干擾。調制的綠光照到熒光物質上使其激發，并發出紅光，由于氧分子可以帶走能量（猝熄效應），所以激發紅光的時間和強度與氧分子的濃度成反比。
ADL系列導軌式安裝電能表不僅在外形和接線上具有靈活方便的特點，而且在功能和性能上也具有下述優點：a.計量正反向有功電量，功率潮流方向自動識別并指示，具有4費率及總電能計量功能。分時復費率功能，日時段可設4費率、8時段，時段內的小時間單位為1min。按月凍結轉存功能，可統計上上月、上月及本月的總用電量和分時電量，用于月用電費的結算及監測用電情況。實時監測功能，測量顯示電壓、電流、頻率、功率、功率因數。
一般來講市面所用的電磁流量計外殼防護等級為IP65（GB428規定的防塵防噴水級），對安裝場所有以下要求：安裝位置要便于檢修和維護盡可能避免測量管內變成負壓，選擇震動小的場所，特別對一體型儀表。避免附近有大電機、大變壓器等，以免引起電磁場干擾。易于實現傳感器單獨接地的場所。盡可能避開周圍有高濃度腐蝕性氣體的環境。環境溫度在-25-1℃和56℃范圍內，一體型結構溫度還受制于電子元器件，范圍要窄些。
