YEWFLO Model VY - ZIMMERLI MESSTECHNIK AG

The Yokogawa VY series vortex flow meter combines advanced digital technology with proven sensor design from the YEWFLO series to ensure reliable and efficient flow measurement for various liquids, gases and vapours.

1. digital technology for efficiency and ease of maintenance
- Remote maintenance and self-diagnosis: Thanks to digital signal processing and advanced self-diagnosis functions, the condition of the system components can be checked at any time. This enables condition-based maintenance, which minimises downtimes and ensures efficient operation.
- SIL2-certified: The VY series supports Safety Instrumented Systems (SIS) with SIL2 safety integrity level, which increases its reliability in safety-critical applications.

2. robustness and long-term stability
- The removable vortex body with two sensor elements and an integrated temperature sensor ensures high long-term stability and robustness, which reduces maintenance costs.
- No complete disassembly required: If maintenance is required, the vortex body can be partially cleaned or replaced without removing the entire flow meter from the pipe.

3. different versions for different requirements
- Standard version: Measures the flow of liquids, gases and vapours. Offers nominal diameters up to 400 mm, a wide temperature range (-40 °C to 250 °C) and pressure ranges up to ASME Class 900.
- Integrated temperature sensor: For mass flow measurements with additional temperature measurement for temperature compensation and more precise calculations of mass flow and energy flow.
- High and low temperature versions: For applications with extreme temperatures. The high temperature version measures up to 450 °C, while the low temperature version can be used down to -196 °C.
- Constricted version: Reduces the installation requirements by reducing the diameter of the sensor to one or two nominal widths. This is suitable for applications where the flow rate varies seasonally.

4. easy integration and maintenance
- The VY series is compatible with the proven sensor design of the YEWFLO series. This means that the flow meter can be installed in the same places without additional pipework.
- Digital signals: Thanks to digital signal processing, pipe vibrations can be effectively eliminated, which further improves measurement accuracy.

5. areas of application
- The VY series is suitable for industrial applications in areas such as chemicals, petrochemicals, oil & gas, as well as for processes where precise and reliable flow measurement is required. Its robustness and ease of maintenance in particular make it ideal for complex systems with continuous operating requirements.

In summary, the VY series' digital technology, flexible design and robust construction help to ensure the efficient operation of systems while minimising maintenance costs and downtimes.
