(3) Space Saving Arrangement
If required straight pipe space is not obtainable upstream of the vortex flowmeter due to existing restrictions
on installation location, the OVAL Honey Vane S combined with a short pipe may be used to get around the
space problem. EX Delta SS with a built-in Honey Vane S requiring no upstream straight pipe is accurate to ±
2% RD in liquid applications. Accuracy varies with the length of short pipe; consult factory for application
assistance.
◦Honey Vane Outline Dimensions
NOTE: The dimensions of honey vane built-in EX Delta (EX Delta SS) remain the same as those of standard
EX Delta, flanged type (see page 49).
