SS2-MVC300-0100 Azbil Corporation - 2 - . Because STEAMcube operates on the same principles as a differential pressure type flow meter, it can produce stable outputs over the entire velocity range even to ultra-low velocities. Therefore, STEAMcube can be used effectively, for example, to measure low flow rates of steam running through of equipment that is kept warm (hot). Self water-sealed structure that enhances maintainability . If a differential pressure transmitter is used to measure steam flow rates, the temperature of the transmitter itself increases as it is exposed to steam. To prevent this temperature increase, a water seal pot (drain pot) is used. However, a number of problems occur when using the water seal pot: the connecting pipe may become clogged by sludge, there is difficulty in controlling the liquid level, there is work needed to keep the pot warm to prevent freezing, etc. . Because STEAMcube employs a self water-sealed structure, steam is cooled and turns into a watersealed liquid which pools in a water pocket set inside a cover flange; this makes it possible to prevent the temperature of the transmitter from increasing. In addition, because sludge returns under its own weight to a steam pipe, it does not pool in the water pocket and, therefore, the connecting pipe does not need to be purged. Because STEAMcube is a differential pressure type flow meter, it provides the advantage that it can be removed from a point of measurement during operation and maintenance can be done for it if the three-way valve (optional part) is used. A vortex flow meter does not provide this advantage. eTube that contributes to a decrease in pressure losses To generate differential pressure, STEAMcube uses the eTube originally developed by Azbil Corporation as a flow element, instead of the conventionally used orifice. Because the eTube has a throttle structure shaped along the line of flow of fluid passing through it, energy losses occurring in the throttle can be minimized. Pressure losses of eTube are about 50% of those of an orifice of the same throttle diameter; so a substantial reduction in pressure losses has been achieved. APPLICATIONS .
