This water consumption sensor fulfills two functions: On the one hand it determines the water consumption in the house or apartment and on the other hand it detects different types of water leaks and sends alarm messages wirelessly in this case.
The sensor consists of two components: a water sound microphone is installed in a suitable place on the water distribution system and connected by a cable to the main unit, which contains the radio communication and data processing electronics. An additional water sensor can optionally be connected by cable.
The water sound microphone 'listens' to the water and detects all activities of the water thanks to the very good sound conduction of water. These are normal water extractions like toilet flushing or hand washing or even unusual events that indicate a leak or other problems with the water.
The Aqua-Scope water consumption sensor permanently delivers the following measured values:
- Normal water consumption per 15 minutes in liters
- Normal water consumption per event (duration and water quantity)
- Water pressure
- Presence of water at the external water sensor
The following alarm messages are transmitted by wireless communication:
The easiest way to install the water microphone is by means of a T-connector under a sink or at another suitable place in the house. A 230 V socket is also required for the power supply.
What Water Sound Microphone measures the absolute water pressure as well as the sound transmitted through the water. It must be installed via a 1/5 inch thread either directly in an inspection opening or via a T-connector to the 3/8 inch connection of an edge valve.
- Connection to Water Pipe: 1/4 inch (G1/4)
- Pressure Range: 0 ... 10 MPa (0 ... 10 bar)
- Acceptable Over Pressure: 20 MPa
- ADC Resolution: 16 bit
- Sample Frequency: 1000 Hz ( one sample every 1 ms)
- Temperature Range: -10 ... + 50 C Celsius
