The long term reliability of the digitalYEWFLO series also extends to the High Process Temperature and Cryogenic models.
With the High Process Temperature model, process fluids with temperatures as high as 450 degrees C can be accurately measured, this is ideal for your high temperature superheated and saturated steam applications.
The Cryogenic model can measure processes at temperatures down as low as -196 degrees C, ideal for low temperature applications such as liquid oxygen.
New functions with Spectral Signal Processing (SSP) technology
Wide process temperature range
Simple parameter settings
Clear, concise indicator
Dual output for analog/pulse
BRAIN/HART communication and key switches for human-machine interface
NAMUR 43 compliant
Remote cable length up to 30m

The FieldMate family effectively supports the initial setup, daily maintenance, and troubleshooting for the maximum utilization of intelligent field instruments. FieldMate is a flag ship product of the FieldMate family which is a PC based full functional and full field protocol configuration tool. The YHC5150X FieldMate Handheld Communicator is the latest HART Communicator from Yokogawa.
FieldMate 3.0 is a PC based tool that enables you to see intelligent field devices clearly, know their condition in advance, and act with agility throughout maintenance work flow.
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.
Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.
