Planning The longer distance to disturbance, i.e. the longer straight duct before the UltraLink®, the higher the measurement accuracy will be. It is not recommended to mount the UltraLink® so that the first flow sensor (* in the table on the next page) is placed on an outer radius of a fitting. Never use an UltraLink® on the outlet side of a duct fan. Place it on the inlet side or in worst case use a flow conditioner if it must be placed on the outlet side.
