The Yokogawa vortex flowmeter YEWFLO DY150/200/250 series represents a pinnacle of innovation and precision in the field of flow measurement, designed to meet the diverse and exacting demands of modern industrial processes. Developed by Yokogawa, a globally renowned leader in industrial automation and instrumentation, these vortex flowmeters combine cutting - edge technology, robust construction, and user - friendly features to deliver reliable and accurate flow measurement solutions across a wide range of applications.
At the heart of the YEWFLO DY150/200/250 series lies the principle of vortex shedding. When a fluid, whether it be a liquid, gas, or steam, flows through the flowmeter, it encounters a bluff body (also known as a shedder bar) placed in the flow path. As the fluid passes around the bluff body, vortices are alternately shed from its downstream sides. The frequency of these vortex shedding is directly proportional to the velocity of the fluid, and by accurately measuring this frequency, the flow rate of the fluid can be determined.
One of the most notable features of the YEWFLO DY150/200/250 is its utilization of Yokogawa's proprietary Spectral Signal Processing (SSP) technology. SSP is a revolutionary approach that analyzes the vortex signal in the frequency domain, separating the true flow - related signal from background noise and interference. This advanced processing technique enables the flowmeter to achieve high - precision measurement even in challenging environments with high levels of vibration, turbulence, or electromagnetic interference.
Features
The YEWFLO DY150/200/250 series offers a wide range of flow measurement capabilities to suit different industrial requirements. The DY150 model is typically designed for medium - flow applications, with a nominal diameter of 150 mm, allowing it to handle flow rates ranging from relatively low to moderate levels. The DY200 and DY250 models, with nominal diameters of 200 mm and 250 mm respectively, are capable of accommodating higher flow rates,, including water, oil, natural gas, steam, and chemical solvents, with an impressive accuracy of ±0.75% for liquids and ±1% for gases and steam under normal operating conditions.
Accuracy is further enhanced by the flowmeters' ability to compensate for various factors that can affect measurement results. Temperature and pressure compensation functions are built - in, ensuring that the measured flow values remain accurate even when the fluid's temperature and pressure fluctuate.
Product Overview
In terms of installation and operation, the YEWFLO DY150/200/250 series offers significant advantages. The flowmeters have a simple, in - line design that allows for easy installation in new or existing pipelines without the need for extensive modifications. They require no moving parts, which not only reduces the risk of mechanical failure but also eliminates the need for regular lubrication or replacement of wear - prone components. Additionally, the flowmeters are equipped with a user - friendly local display and interface, which provides real - time information on the measured flow rate, total flow, and other relevant parameters. Operators can easily configure and calibrate the flowmeters using the intuitive menu system, and the devices support a variety of communication protocols, including HART, FOUNDATION Fieldbus, and PROFIBUS, enabling seamless integration with existing industrial control systems for remote monitoring and control.
The YEWFLO DY150/200/250 series also excels in its diagnostic capabilities. The flowmeters are equipped with advanced self - diagnostic functions that continuously monitor their own performance and detect any potential issues or anomalies. In the event of a fault, such as a sensor failure, signal interference, or abnormal flow conditions, the flowmeter can generate detailed diagnostic messages and alarms, which are transmitted to the control system for prompt attention. This proactive diagnostic approach helps to minimize downtime, reduce maintenance costs, and ensure the safe and efficient operation of the industrial processes in which the flowmeters are installed.
