... that are wrong, such as bad meter readings. This process is much easier if the model tuner follows some basic procedures. Pipe segments and pump or compressor stations should be isolated (in the model), so that tuning one thing doesn’t knock something else out of tune. Tuning is also easier if it’s done...
