Figure 10.
When the flowmeter is installed at the back end of the valve and the valve is not fully open, the flowmeter
and the back end of the valve need to ensure a straight pipe section of at least 10D, as shown in Figure
11.
Installation Direction
When installing, the positive direction of liquid flow should generally be the same with the direction of the
arrow on the sensor, and there must be sufficient space for installation and maintenance near the
flowmeter. During installation, the flowmeter should be equipped with supports on both sides of the
pipeline to prevent the flowmeter from being stressed due to pipeline vibration, impact and contraction.
When installing the flowmeter, in general, with horizontal installation, please ensure the axis of the
measuring electrode is approximately horizontal; if the axis of the measuring electrode is perpendicular
to the ground, bubbles can easily build up near the upper electrode which is easy to block the liquid from
contacting the electrode below that is easily covered by mud or impurities. The converter is generally
installed above the pipeline to prevent water from entering the converter.
When installing the flowmeter, please ensure the axis of the pipeline and the flowmeter measuring tube
are in the same straight line. If there is an angle between the two axes, the flange connection will not be
sealed well, and even the flange welding part will break
