Remove bubbles from the flow cell

Two types of air or gas bubbles can be present in the sample:

• Bubbles that cannot be seen—made when air is absorbed into liquid.

This can occur naturally or be the result of human intervention such as when ozone is injected into water to act as a disinfectant. Bubbles that cannot be seen in the sample form and can be seen in the flow chamber.

• Bubbles that can be seen—made when liquid and air are mixed. For

example, when water flows through a pipe that contains air or when water falls.

Decrease the sensor outlet flow

Remove bubbles that cannot be seen in the sample but can be seen in the flow chamber. To do this, decrease the sensor outlet flow to apply pressure to the sample while it is being measured.

1. Keep the flow rate through the sensor within the specified limits. Refer to Specifications on page 3.

2. Install a flow restrictor in the sensor outlet tube.

3. Adjust the flow restrictor until the flow is slightly decreased.

4. Close the 3-way valve to stop flow through the sensor.

English

5. Drain the flow chamber.

a. Turn the internal 3-way valve handle to the CALIBRATE position. b. Remove the funnel from the holder and hold it below the sensor

height to drain any sample that is still in the sensor.

c. When the sensor is drained, put the funnel in the funnel holder.

6. Slowly open the 3-way valve to let the flow chamber fill with the

sample.

Use an external bubble trap

Remove air bubbles that can be seen from the sample with an external bubble trap. Refer to Replacement parts and accessories on page 27. The manufacturer recommends the use of an external bubble trap for flow rates higher than 1.9 LPM (0.5 GPM).

1. Install the external bubble trap vertically (air vent up) and upstream of the sensor. Refer to the instructions supplied with the external bubble trap.

2. Make sure that the air vent is open. Bubbles will stay in the liquid when the air vent is closed.

3. Periodically remove the bubble trap drain plug to let any collected sediment sludge drain.

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。请参阅规格第 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第 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。
