Method facilitating the identification of buried appliances along water mains |
摘要 |
The driving squares for the valves are raised up by means of pegs of different lengths (weights). The length of a raised square defines the class of valve in question, which facilitates identification thereof. The length of the raised square may be measured from the surface with the aid of the operating key and of its rod. <IMAGE>
