What's the difference between a pulse rate of 10 and pulse rate of 95 or 100 for my oil, coolant, ATF and other non-fuel fluids?

Use pulse rate to identify type of pulse meter

A pulse rate of 10 indicates a Badger Pulse Meter, which is commonly used for fluids like ATF, oil, and coolant (refer to image 1 for an example). 

On the other hand, a pulse rate of 95 or 100 signifies a K400 Piusi Pulse Meter. 

To simplify installation and avoid the need for re-calibrating settings, it is recommended to replace a Badger Pulse Meter with another Badger, and a K400 with another K400.

Image 2 Pulse rate 95 is the K400. Sometimes it's a 100 instead of 95 but it's still the K400.
