| Abstract: | Delta-T method ultrasonic flow measuring System is designed in order to solve the flow measurement in ground source heat pump. The system collect the flow data, packet and encrypt the data ,communicate with the remote server at fixed time intervals by STM32F407 ZE. It accurate measure the transmission time of ultrasonic propagation in the medium with the Delta-T method by TDC-GP22 and MSP430F2618 . Finally the system realized the velocity and flow rate measurement in real-time. It is proved can upload the flow data to the remote server by test, it can meet the needs of flow measurement for ground source heat pump. |
