Product description Brand name and product description

Hidrosonico is a sonar-based stream gauge, which reads the distance between the sensor (specifically from where the housing meets the threading) and the water’s surface directly below and sends this data at specified intervals to cloud-based storage, SMS, and/or email as determined by the user. The product was designed to aid in collection of hydrological data and for flood early warning in developing countries.

It has been implemented already in countries such as Cambodia, Honduras, Nepal, and Indonesia.Interview with manufacturer
