除去流动槽中的气泡

样品中会出现两种类型的气泡:

一种是不可见气泡

 - 

因液体吸收空气而形成。这属于自然情况,或是人

为干预所致,比如向水中注入臭氧作为消毒剂。样品中形成的不可见气
泡在流动槽中可见。

另一种是可见气泡

 - 

因气液混合所致。比如水流经含有空气的管道时或

水降落时。

降低传感器的出口流量

消除样品中不可见但是流动槽中可见的气泡。为此需要降低传感器的出口
流量,以便在测量样品时对样品加压。

1.

使流体通过传感器时的流速保持在指定限值内。请参阅

规格

 

 29

2.

将一个限流器安装在传感器出口管中。

3.

调整限流器,直到使流量略微降低。

4.

关闭三通阀截断流向传感器的流体。

5.

排空流动槽。

a.

将内部

 3 

通阀手柄转到

 CALIBRATE

(校准)位置。

b.

从漏斗座上取下漏斗,并使其低于传感器高度,以排放传感器中残
留的任何样品。

c.

排放传感器之后,将漏斗放在漏斗座中。

6.

缓慢打开三通阀,使流动槽充满样品。

使用外部除泡器

利用外部除泡器除去样品中可见的气泡。请参阅

更换部件与附件

 

 49

制造商建议为高于

 1.9 LPM (0.5 GPM) 

的流速使用一个外部除泡器。

1.

将外部除泡器垂直安装在传感器的上游(向上排气)。请参阅外部除泡
器随附的说明书。

2.

确保排气孔畅通。关闭排气孔时,气泡会留在液体中。

3.

定期取下除泡器排放塞,以便排出所收集的任何沉积淤泥。
