Hot water content or charge status determination arrangement for hot water storage heater

摘要: The arrangement has a temperature sensor (11) near the outlet and an long, extended (10) on outside of tank, to monitor spatial distribution hot water. processor microcontroller (13) are calibrated maximum setting, which is labelled as 100% setting. Signal processors (14,15) i.e. A-D converters, pass signals microcontroller. signal level (15) from at working 100%. Subsequent heating cycles monitored against this upper determine relative state storage system.
