管道密度计的安装注意事项，西安华恒仪表介绍：管道线密度计经常安装在工作条件较为恶劣的现场,为了尽可能减少密度计工作条件的恶劣程度，应尽量安装在温度梯度和温度变化小，无冲击和振动的地方，无气泡。只有充分考虑现场特有条件，才能发挥其应有的精度指标。安装时注意以下事项：
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）产品必须竖直安装，与地面垂直度不大于5度（如安装不垂直，或本地重力加速度偏离标准重力加速度时，将产生偏差，后面将介绍如何消除因此而产生的偏差）。
（2）侧面安装时法兰直管段要保证能够顺利装入。
（3）打开电气盒的表盖后，重新安装时应拧紧以保证与密封O型圈紧密接触,如果不拧紧，湿气会进入电气盒内，影响电路正常工作。
（4）密度计外壳必须有效接地。
（5）安装位置尽量远离变频器或大功率电机，必要时采取隔离措施，使用屏蔽电源线。
（6）安装好后，空管时调零，使密度值显示为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_.
