History of YOKOGAWA's Vortex Flowmeter
Yokogawa launched the world's first vortex flowmeter in 1969.
For over 50 years, the long-term stability and high accuracy characterized by Yokogawa Vortex flowmeters has continued to improve customer productivity. Sales of over 500,000 units is a testament to the reliability of the YEWFLO series. In 2022, we launched the latest series of YEWFLO, the Vortex flowmeter VY series.
The history of YOKOGAWA's vortex flowmeters dates back to 1969 when we launched insertion-type flowmeters for flare stacks.
In 1979, we launched the general-purpose vortex flowmeter and in 1981 we launched YEWFLO*C with the base sensing structure. In 1992, we introduced YEWFLO*E, which excelled in noise resistance. The structure of the YEWFLO*E has evolved with the latest VY series.
In 2000, we launched the digitalYEWFLO series, which have our proprietary digital signal processing technology SSP. This digitalYEWFLO series pioneered a new stage for vortex flowmeters with automatic noise removal functions and diagnostic functions.
Furthermore, to meet various needs and support applications of our customers, the YEWFLO series has continuously evolved. In 2002, we released the Built-in Temperature Sensor type that can calculate saturated steam flow with a single unit. In 2006, we introduced the Reduced Bore type for smart piping. Moreover, in 2012, we launched large-diameter models (up to 400 mm). These specifications are, of course, also available in the vortex flowmeter VY series.
In 2022, we launched the latest VY series, continuing the history of YOKOGAWA's vortex flowmeters.

- All the instrument information is fully integrated with the instrument management system.
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.
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.
Vortex flow meters utilize a fluid phenomenon in which frequencies of Karman vortex streets released from a shedder bar inserted in a flow are proportional to flow velocities.
Vortex flow meters have been appreciated by users as volume flow meters, which can, in principle, be applied to any flow measurement of liquid, gas, or steam. Volume flow measurement is enough for substances with small variations in density such as liquid.
The operating principle of the vortex flow meters YEWFLO series, which first became commercially available in 1979, is based on the phenomenon in which the frequency of a Kàrmàn vortex train that occurs from a vortex shedder placed in a fluid flow, is proportional to the speed of that flow.
