户表改造中水表保温措施研究

针对户表改造中水表的防冻保温措施进行了研究，为了解决北方城市冬季水表的冰冻问题，通过试验，研究了不同湿式水表的防冻性能，水表外套保温材料延长对水表冻结时间的影响，并验证了现阶段使用的单只水表表箱的防冻性能。

The water meter attemperator in water meter reconstruction is studied, for resolving the problem of water meter frosting in winter in the northern city. In the experimentations, the prevent frostbite capability of different liquid sealed meters were studied, and the influence of water meter freeze time extended by jacketed insulation materials were reviewed, and the prevent frostbite capability of single water meter box which is using now were verified.
