System features: The data transmission radio communication method is more suitable for the communication business of wireless monitoring systems. In online flow monitoring, there is a large amount of data that needs to be collected and recorded by staff in a timely manner. If all of this data needs to be manually collected and recorded, it will inevitably result in a huge workload for staff and low efficiency. At the same time, it can achieve monitoring of cumulative flow, instantaneous flow, pressure, temperature, fluid density, and internal time of instruments, and more data can be collected by adding on-site instruments. The collected parameters can be output through reports or displayed and printed in the form of trend curves, so that the management department can detect abnormal situations in a timely manner.
