Azbil Corporation SS2-MVC320-0100 - 9 - Condensate must not pool or stagnate in a pipe! Do not install STEAMcube in a position where condensate may pool or stagnate inside a pipe. Before starting the installation work, check the position where STEAMcube is to be installed to make sure that condensate does not pool or stagnate inside a pipe. Caution for the noise of steam In some piping, the flowmeter may generate noise or vibration. In order to avoid the noise/vibration, it is suggested not to install the flow meter close to the tee pipes, valves, bent pipes and filters. If condensed water flows in the flowmeter and flasehs, significant noise may be generated. Install the flowmeter the place where the condensed water CAUTION flows. . Prevent condensate from pooling in the pipes. A large amount of condensate in a pipe can cause a water hammer that may affect not only the flowmeter but also the downstream devices. Note that pooled water may also produce differential pressure not due to flow. In such a case, output is generated when there is no steam flow. When installing the flowmeter, be sure to install a steam trap nearby to discharge condensate. If the direction of steam flow is reverse to that of drain flow in sloping piping: Two-phase counter flows occur, and condensate may pool inside a pipe. If a valve on the primary is opened and that on the secondary is closed in horizontal piping: Because steam continues flowing from the primary, it is cooled before it reaches the valve on the secondary, causing the pipe to be filled up with condensate.
