Plot Runoff Process Observation Instrument

1. Product Introduction

The Plot Runoff Process Observation Instrument is a new type of equipment independently developed by our company for automatically monitoring and recording the flow process in runoff plots. It is designed based on fully absorbing and referencing current techniques for measuring slope runoff flow, and in accordance with the actual needs of the second phase of soil and water conservation monitoring. It is primarily used for monitoring and recording the runoff yield of specific small watersheds and the flow generation process in field runoff plots.

(1) This set of equipment is suitable for monitoring surface runoff in soil and water conservation runoff fields.

(2) Before installing this equipment, the user must construct a runoff field. If a runoff field and collection pool have already been built, installation can proceed directly, but it is essential to ensure a 50 cm drop between the outlet and the ground.
