In order to solve the problem of large amount of labor and the error of readings during the manual measurement
a simple automated disc infiltrometer is designed.It links a differential transducer and a data logger and gets infiltration data automatically.The principle and components of the disc infiltrometer
the combination mechanism of the differential transducer with the water storage pipe
and mathematical process used in the data logger are studied.The accuracy of data readings and reliability of application of the device is verified by the tests of free infiltration
