A principal vantagem do piezômetro pneumático é que ele tem menos interferência na área do projeto, pois não há necessidade de fios ou cabos para transmitir os dados. No entanto, ele precisa de calibração periódica dos manômetros e recarga das garrafas de gás comprimido (nitrogênio). Além disso, a confiabilidade da medição de pressão negativa é menor e o tempo de resposta de leitura é relativamente pequeno. Portanto, a alternativa correta é a letra c) I, III e IV estão corretas.
