1. Product Introduction

The WFH-2A full-range mechanical encoder water level gauge is used to observe changes in water levels of rivers, lakes, reservoirs, canals, groundwater, and other water bodies. It converts these changes into switch digital outputs through mechanical encoding, making it suitable for water level data collection, transmission, processing, display, recording, and storage by hydrological stations, flood control departments, water resource and water environment monitoring agencies, as well as related research institutions.
