HydroLevelControl is a bundle of hardware and software. Is designed to easily control the levels in reservoirs, pools, etc. Depending on the sensor, it can measure and control a fluid up to 21 meters, or even more (by request).
Mounting the device on a panel is easy, just make a hole with a dimension of 97 x 72mm. On the backside are the connectors for sensors, power supply, and relays. It uses 220VAC for power but can be powered over a USB port too.
The device has integrated two relays that can be configured independently from each other. Also, there is an alarming system with a sound buzzer and visual LCD background blinking, both independently configurable.
