I'm afraid that it should be:

Code:

// --- Vector A100R ---
#if (WSpeedSensor_Type == 72)   // Vector Intruments, model A100R : Speed Pulse/sec 1.25 m/s
#define ClickPerRev  1
#define FORM_FACTOR  1.25
#endif

Your collection of weather instruments is impressive. The Weatherduino Pro2 system is thankful for that  

Of course, I should have seen that! Collection built up over years mostly off ebay, buying parts of systems to keep others going.
