Overview
Vortex Flowmeters, Ideal for Steam Flow MeasurementVortex flowmeters are highly versatile flowmeters that can measure liquids, gases, and steam over a wide range of temperatures and pressures. The advantages offered by this type of flowmeter make them better suited than other types to measuring steam flow. The vortex flowmeters in Yokogawa’s VY Series offer a wide measurable flow range of up to 400mm in connection size, as well as the ability to measure fluids at high temperatures of up to 450°C and high pressures of up to ASME Class 1500. In addition to excellent solidity and stability, the series has been added with remote maintenance and self-diagnostic functions that help ensure efficient maintenance, supporting long-term stability of plant operations and improved production efficiency.
Benefits
This section describes the advantages of using vortex flowmeters for measuring steam flow, comparing them with orifice flowmeters (differential pressure flowmeters), which are used at many work sites.
Wide Rangeability to Accommodate Fluctuating Steam Flow Rate
Low Pressure Loss Helps Ensure Stable Operation
No Mechanical Moving Parts, Less Prone to Failure
Application
- Those who want to improve the efficiency and stability of device operations by using temperature and pressure compensations to measure steam flow rates with higher accuracy
- Those who want to minimize downtime by implementing predictive maintenance based on device conditions
- Those who want to reduce maintenance costs through component-based maintenance of device
