   管道密度計的安裝注意事項,西安華恒儀表介紹:管道線密度計經常安裝在工作條件較為惡劣的現場,為了盡可能減少密度計工作條件的惡劣程度,應盡量安裝在溫度梯度和溫度變化小,無沖擊和振動的地方,無氣泡。只有充分考慮現場特有條件,才能發揮其應有的精度指標。安裝時注意以下事項:

  Pipeline densitometer installation matters needing attention,Xi'an Huaheng Instrument:Pipeline densitometer is often installed in the site with poor working conditions.In order to minimize the bad working conditions of densitometer,it should be installed as far as possible in the place where temperature gradient and temperature change are small,there is no impact and vibration,and there are no bubbles.Only by taking full account of the unique conditions of the site,can we give full play to its due accuracy index.Attention should be paid to the following items when installing:
 
  (1)產品必須豎直安裝,與地面垂直度不大于5度(如安裝不垂直,或本地重力加速度偏離標準重力加速度時,將產生偏差,后面將介紹如何消除因此而產生的偏差)。
  (2)側面安裝時法蘭直管段要保證能夠順利裝入。
  (3)打開電氣盒的表蓋后,重新安裝時應擰緊以保證與密封O型圈緊密接觸,如果不擰緊,濕氣會進入電氣盒內,影響電路正常工作。
  (4)密度計外殼必須有效接地。
  (5)安裝位置盡量遠離變頻器或大功率電機,必要時采取隔離措施,使用屏蔽電源線。
  (6)安裝好后,空管時調零,使密度值顯示為0g/cm³。
 
  (1)The product must be erected vertically,and the verticality with the ground is not more than 5 degrees(if the installation is not vertical,or when the local gravity acceleration deviates from the standard gravity acceleration,there will be deviation.How to eliminate the resulting deviation will be described later).
  (2)Flange straight section should be installed smoothly during side installation.
  (3)When the cover of the electric box is opened,it should be tightened to ensure close contact with the sealed O-ring.If not tightened,moisture will enter the electric box and affect the normal operation of the circuit.
  (4)The shell of densitometer must be grounded effectively.
  (5)The installation position should be as far away as possible from the frequency converter or high-power motor.If necessary,isolation measures should be taken and shielded power cord should be used.
  (6)After installation,the ATC will be zeroed so that the density value can be displayed as 0 g/cm_.
