The UMA is an advanced and highly accurate (Up to R400), anti-destruction, valve integrated, prepaid ultrasonic water meter and data end-point for residential applications. With no moving parts, the UMA is able to be reliable and long lasting precision.With its robust fully-wrapped design, the UMA is anti-destruction and IP68 protection. with its high dynamic range, making it the best solution for addressing NRW. The UMA is fully IoT ready-NB-IoT, Lora Private network, LoRaWan, Sigfox, GPRS, Wmbus. It is easy for you to built AMR/AMI system.

  • High Peformance

    The UMA measures the water 4 times in 1 second, as well as its intelligent data error correction technology, making the measurement high accuracy and stability. The UMA's ultrasonic technology leverages IFA TECHNIQUES's years of experience with its ultrasonic meters.

· Installation in any position

· No air measuring 

· Indifferent to sand and particles in the flow

· Bi-directional flow measurement

  • 3 types optional battery life span & Replaceable battery

    Due to UMA's low power consumption and its IP 68 register,with no moving parts , fully-wrapped,anti-destruction design,and its body is made from durable pps composite. This robust design makes the Ufo mainte- nance-free and highly precise throughout its exceptional battery life span. We consider it to be perfect, so we design the battery is replaceable and it is also IP68 protection.

  • Optimum Antenna Design

    Due to our engineer's effort and draw the lesson from the past, The UMA's antenna apply vertical polarization, pcb and antenna perfectly match, make sure the meter have optimum signal, means the meter can have long distance and more signal coverage.

  • IP 68 Design

    Because of the water molecule will penetrate into the plastic under the extremly condition, strictly speaking the plastic housing is not water-proof. The UMA's IP68 design solves this problem, to make sure itself to be IP68 protection.

  • The solution for addressing NRW

          With its highly accurate calculation and intelligent error correction technology, the UMA is powerful solution for addressing NRW-detecting leaks, pipe burst, when above happens, you can control from your AMR            system as well as improving consumer's awareness and satisfaction. Increased revenue with registration of previously un-metered water.

  • Data End Point

    The UMA data collection and logging capability can provide a high resolution detailed local consumption profile and help utilities inform customers on unusual consumption patterns or events. This promotes customer engagement and resource awareness. Multiple settable alarms and events include Leaks, Backflow, Blank pipe, Pipe Bursts available. The non-volatile flash memory ensures no data loss even in cases of end-of-battery.

  • IoT: Internet of Thing

    The UMA is a data collection end-point device coupled with LPWAN communication module, providing the foundation for a reliable and scalable AMR network such as NB-IoT, LoRa private network, LoRaWAN, Sigfox, GPRS and so on.
