Water Monitor
Real-time Water Monitor On 25-08-2004 I installed two water pulse counters into the central water system. With these counters we are able to count real-time the amount of water used. The pulse rate are 1 for every 0.5 liter (0.13195 Gallon) of water used. We now can monitor total use of cold and Hot Water separately. The total water count is including hot water. Below you find charts of the last 24 hour, 24 day's and 24 weeks. Put your cursor on de chart bars to see the exact readings.
Real-time Total Water use counter
The Real-time water counter below is updated real-time and displays the Cubic Meter (m³) water used. The counter is exactly synchronic with the counter of the water company!

Real-time Water Monitoring We use two extra (Alaxa) water meters with a pulse counter. One is installed where the water is entering the house and the other is installed on the central heating system which provides the hot water. The pulse counter is connected to a RFXmeter from RFXCOM. Once every 30 seconds the RFXmeters sends all the data to my Home Automation system which writes all the data to a SQL Server!
