4.Application:
Eg. Voice alarm prompt: when oil tank is leaky, if there is just alarm sound, people cannot instantly know where the failure occurs. So need technical staff to check first, then they can know what’s the problem.
But if the oil tank alarm can tell what’s the problem, that would be much better, right?
Our company can provide you oil tank voice solution to you. According to different gas stations and petrochemical factories, audio content can be changed.
