3151智能型液位变送器是作为在石油开采,水利水务,化工制造.工业水处理等众多方向使用的一种主要自动化仪器仪表之一,在西安仪表制造厂家生产上提供运输服务时候,时长会被提到运输问题,

在运输及存储过程中确保高压侧法兰膜片和低压侧测量端的完整性及密封性，避免测量元件被伤害到。

During transportation and storage, ensure the integrity and sealing of flange diaphragm at high pressure side and measuring end at low pressure side, so as to avoid damage to measuring elements.

工作原理

working principle

液体具有静压现象，其静压力的大小是液柱高度与液体重度的乘积，对于A点而言，将有

The static pressure of liquid is the product of liquid column height and liquid gravity. For point a, there will be

PA=PB+ρgH

PA=PB+ρgH

ρ— 液体密度

ρ - liquid density

g— 重力加速度

G - acceleration of gravity

h—被测点到液面的 高度（深度）

H - height (depth) from the measured point to the liquid level

则 h=P/(ρg)

Then H = P / (ρ g)

压力式液位计正是利用液面下压力与深度成正比关系来检测液位的

The pressure type liquid level gauge uses the direct ratio between the pressure under the liquid level and the depth to detect the liquid level
