An electrically insulated water meter prevents electrical current from flowing between in-house plumbing and a water main. Known water meters are connected to water mains and to in-house plumbing through metal couplings and metal pipes. The metal pipes, metal couplings, and a metal water meter housing complete an electrical circuit allowing the flow of electrical current. Such electrical current causes water mains and services to corrode and deteriorate thus shortening their life span by causing leaks and breaks, and is also a health risk for water company employees who risk electrical shocks due to the electrical current. The electrically insulated water meter includes non-conducting couplings between the water meter housing and the water pipes connected to the water meter housing, to prevent the flow of electrical current. Including the non-conducting couplings on both sides of the water meter housing prevents the electrical shocks to the water company employees. |
