By measuring the height of the top of the metal rod installed on the buried piping, the amount of subsidence of the underground piping is indirectly measured.
■Construction To secure small base fittings with stainless bands, they can be easily fixed to pipes of any diameter, from small to large. ■Low Cost By using the "external thread + high nut connection method," we reduce the processing costs of the rods, achieving low costs.
