With a transducer spacing of 62mm and a height increase of only 2.6mm compared to independent transducer solutions, this module can be seamlessly integrated into the majority of Chinese flow tube sections, allowing the original product form factor to remain unchanged.
The module's high-precision metering algorithm extracts the hydrodynamic characteristics of different flow tube sections, achieving metering performance with an R800 turndown ratio. Furthermore, it enables a two-point calibration production process, improving calibration efficiency to approximately 10 minutes per meter.
Featuring a highly integrated design, this module incorporates mathematical and intelligent design for the most technically challenging aspect of ultrasonic water meters-ultrasonic metering technology-directly outputting measurement results. This significantly lowers the technical barrier for ultrasonic water meter development.
