HOT WATER CONSUMPTION MONITORING Symmetron Electronic Applications

HOT WATER CONSUMPTION MONITORING Symmetron Electronic Applications

Measure in order to be able to manage. • Via the extended monitoring of your business’s hot water network, you can extract useful conclusions and gain economic and other benefits. • Obtain information, graphs and statistics that can not be extracted from the total oil (as main or backup heating source) bill and get the complete picture of the energy consumption of your business.

Benefits • Detect which hours and in what quantities the hot water is consumed. • Calculate the water and oil consumption per hour, day, month or year. • Decide the changes required in the heating methods. • Check how much the backup heating methods cost (oil, etc) • Create time and customer profiles in relation to consumption.

Water flow and temperature statistics per hour • Monitor the incoming water flow in your water circulation pump and the returning flow. Their difference is the consumption. Moreover, measure the water temperature at the input and at the return, in order to monitor the heat loss due to the hot water usage. Which hours of the day, do you detect the greatest consumption and heat loss?

System architecture

System architecture • The basic system Symmetron offers includes : – A data logger with an optional telemetry module. – Flowmeters at various points of your installation, such as at the input and output of your water circulator, for – – • • consumption calculation (the difference between the two) or at the cold water supply as well Water thermometers (submersed probes) at the input and output of your water circulator, for calculation of the heat loss due to the hot water usage Connection of the oil burner with a relay, in order to measure its operation time. How much time is required for the oil burner to operate as a backup heating method? The data logger records the measurements in its internal memory and in a removable 2 GB Micro. SD memory card, with long-term data logging capacity. The data retrieval directly from the data logger can be done as follows: – Locally, via a serial cable – Via LAN/ internet, via a built-in Ethernet module. – Via GSM/ GPRS, via a built-in modem.
