Instrumentation device to the amount of water used by the user is a water meter by measuring management stability is necessary. But with the onset of winter to meter water was ice inside the phase change and about 9 % and increase the volume of the meter is damaged. The existing protection bleed water meter freeze protection technology into three great bootong, supplying the heat insulation inside the external protection, water metering for water meter in the freeze protection will be divided into installing the device. Not see how far the structure for the commercialization of new technology-based products and aims to develop technologies that do not require an external power supply. Thus, freeze more vulnerable by internal pressure of the interpretation applied to a water meter in temperatures below zero internal pressure to confirm the area of preventing damage and freeze protection that can reduce the effect is superior to develop a water meter.
