Portable instrument for monitoring earths surface dome sheet flow

The utility model relates to a portable flow monitor of the overland slope runoff, which is provided with a water supporting bucket which is formed through connecting a supporting groove and a guiding bucket, the potential energy and the kinetic energy of an measured water flow can be reduced after the measured flow passes through the water supporting bucket, thereby the effect to the weighing of the flow quantity of the runoff by the energy is reduced, the flow monitor further comprises a weighing pipe which is connected with the water supporting bucket through adopting a pipe joint type rigid connection, and the up-and-down movement during weighing the weighing pipe is realized through using a steel shaft structure, and the weighing pipe is also connected with a sensor through adopting the rigid connection, which enables the structure to be completely fixed and to be convenient to transport and carry. The rigid connections between the weighing pipe and the water supporting bucket, and between the weighing p
