Reduced Bore Type
digitalYEWFLO Vortex flowmeter Reduced Bore Type is a vortex flowmeter in which the main body of the vortex flowmeter and the reducer (reduction pipe and expansion pipe) are integrated into a casting.
Suitable for lines with large fluctuations in flow rate depending on the season, such as steam supply lines.
Since the reducer and the vortex flowmeter are integrated, it is not necessary to prepare a reducer and a short pipe for securing the straight pipe length.
This not only simplifies installation and reduces costs, but also improves safety by reducing the number of connection points.

Resources
Measuring energy consumption is an important factor in the quest to improve energy efficiency. Efficient and accurate metering is paramount to determining excess use, along with an accurate picture of where the steam is being used. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality. Traditionally the most common method of steam metering is the orifice plate and differential pressure transmitter technique. General areas of concern with this type of measurement are the orifice plate's susceptibility to wear introducing immediate inaccuracies, the relatively high permanent pressure losses introduced into the system by the orifice place and the small measuring range, typically 3:1.
Yokogawa's digitalYEWFLO Reduced Bore Type Vortex Flow meter features a cast stainless steel body and a concentric reducer and expander that enable stable flow rate measurements in low-flow conditions. This expands the range of measurements that can be performed, from the higher flow rates down to the lower end of the flow span, which is normally difficult for Vortex Flow meters, and ensures stable and accurate flow rate output.
It is estimated that almost two thirds of oil discovered in the United States lies unrecovered trapped in porous formations. There are approximately 500,000 abandoned wells containing such oil. Because of this fact oil companies are constantly pursuing methods for the recovery of this oil.
