ABB Watermaster flow meter service password needed

Installing a new Watermaster flow transmitter on an older master flow tube.
The transmitter is setup for a smaller mag sensor and will not allow me to change the type of sensor or the size.
Contacted engineer from ABB for the service password but they do not work so I cannot access the service menu.
No solution from ABB at this point.
This is a critical part of our process and my only alternative is to remove the transmitter and flow tube and replace with another set.
Anyone ever experienced the setup with this unit using the service password?
