How it works?

Simple, fast and reliable solutions to transfer data over network

Data Processing

In above animation you can see the process of water flow measurement, data collecting and transmitting to the provider via dedicated wireless radio repeater. Whole infrastructure operates in one of three desired frequencies (169, 434 or 868MHz). Data received this way is collected and further processed in providers data center. After automated processing, all the data are available to both parties – provider and customer via Web interface or Smartphone application.

No mechanics – No failures

Ultrasonic flow-meters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency shift increases linearly. The transmitter processes signals from the transmitted wave and its reflections to determine the flow rate.

Transit time ultrasonic flow-meters send and receive ultrasonic waves between transducers in both the upstream and downstream directions in the pipe. At no flow conditions, it takes the same time to travel upstream and downstream between the transducers. Under flowing conditions, the upstream wave will travel slower and take more time than the (faster) downstream wave. When the fluid moves faster, the difference between the upstream and downstream times increases. The transmitter processes upstream and downstream times to determine the flow rate.
