ADWL launched by akvodropsTM is designed with basic functions with food-class paraphenylene amide PPA with fiber glass composite material. It combines years’ experience in ultrasonic technology, adopting state-of-the-art technology and sophisticated testing. It has been proven that ADWL is reliable and absolute matured achievement in high accuracy measurement. In addition, the special compact design does completely assure the quality of water-proof protection. The accuracy is guaranteed even if it is installed under water in a long time. Moreover, the core engineering concept of ADWL aims at cutting down the budget on overall operating costs from remote meter readings (AMR).
