The digital YEWFLO vortex flow meter combines the field proven sensor and body assembly used in more than 450,000 units installed worldwide with a unique and powerful combination of digital technology that includes spectral signal processing (SSP), a Yokogawa innovation. The digitalYEWFLO vortex flow meter is accurate and stable, even in harsh process conditions, and has a highly reliable and robust design that delivers improvements in plant efficiency and reduced operating costs.
digitalYEWFLO Vortex Flowmeter Standard Type can measure flow rate of liquid, gas and steam.
A simple and robust structure with no moving parts provides high reliability and durability, and supports a wide range of applications.
Can Be Used in a Wide Range of Applications
It can measure the flow rate of liquid, gas and steam.
Installation at piping is easy because there are only two upstream and downstream connections.
The sensor detects frequency, and at zero flow rate it outputs frequency zero. Therefore, no zero adjustment is required.
Durability
Durability through simple design and construction.
