Vortex Flow meter VY series

Vortex 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.

Steam is the most commonly used high-temperature, high-pressure heat medium across a wide range of industries. For example, it is used for heating, distillation, and concentration in chemical plants; sterilization, disinfection, and cleaning in biotechnology, food, and pharmaceutical plants; and air conditioning in semiconductor plants and district heating/cooling plants, among many other applications. There are two types of steam: saturated steam and superheated steam. Saturated steam is a fluid with good thermal efficiency, but it is difficult to maintain saturation due to the pressure loss and heat radiation associated with steam transportation, so it is sometimes supplied in a superheated state at higher temperature and pressure. Vortex flowmeters are chosen as the best flowmeter for steam flow measurement at many facilities because they can measure the flow rate of even high-temperature, high-pressure steam, including superheated steam.

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.
