Judge Diane Gibbons announced her verdict Tuesday afternoon.
Meyerle, 35, presented no defense after prosecutors wrapped up their case last week.
Over four days Bucks County prosecutor Jennifer Schorn presented to the court victim testimony, a child pornography collection allegedly seized from Meyerle's home and text messages he allegedly exchanged with one teen.
Authorities say Meyerle traded a tattoo for sex with a 15-year-old girl last year, sparking an investigation that led to additional charges.
Meyerle requested a stipulated waiver trial at which prosecution evidence is put on the record and a judge determines the verdict.
A sentencing date has not been set pending a Megan's Law evaluation.
