3151插入式在線密度計是一種在線測量液體密度設備，可直接用于工業生產過程。產品根據阿基米德原理，采用現代化技術采集信號，并對儀表進行了溫度補償；在總結各種液體在線密度測量經驗并對工業現場做了大量研究，本著簡單實用的原則生產制造。

1、在規定溫度環境使用
1. Use at specified temperature
使用在線密度計，要在規定的溫度環境范圍內使用，不要超出其具體的溫度，承受環境付出現在，甚至可能還會對工作環境造成危險和影響，避免造成危險情況，就要按照規定要求進行使用。
When using on-line densitometer, it should be used within the specified temperature environment, and should not exceed the specific temperature. If the bearing environment appears, it may even cause danger and influence on the working environment, so as to avoid dangerous situations, it should be used according to the specified requirements.
2、不要有錯誤違規操作
2. There should be no wrong and illegal operation
在線密度計，使用功能很強大，并且特別安全可靠，尤其是使用壽命很長，但這并不代表不需要特殊的維護和保養。除了平時要正確的操作使用之外，還要避免各種違規操作，確保在安全的環境下進行工作，更不要再出現故障時帶病工作，每6個月要進行定期檢查。
The on-line densitometer is very powerful, safe and reliable, especially for a long service life. However, it does not mean that special maintenance is not required. In addition to the normal use of correct operation, but also to avoid all kinds of illegal operation, to ensure that the work in a safe environment, not to mention the failure of work with disease, every six months to carry out regular inspection.
3、避免重物磕碰碰撞
3. Avoid heavy object collision
在線密度計需要安裝在合適的環境中，尤其是要保證周邊環境安全，符合安裝要求，避免有重物磕磕碰碰，否則很容易出現嚴重故障和意外情況。
The on-line densitometer needs to be installed in a suitable environment, especially to ensure the safety of the surrounding environment, meet the installation requirements, and avoid heavy objects bumping, otherwise it is easy to have serious faults and accidents.
