Various types of drainage pipes and fire hydrants are installed in the process of building or civil engineering works. And, after construction, water pressure measurement is performed to check whether proper water pressure is formed in the drain pipe and fire pipe, and whether there is a leak. A hydrometer is an instrument for measuring water pressure. In general, a magnetic-recording hydraulic pressure gauge is a portable device that measures water pressure in a drain pipe or a water supply pipe, and refers to equipment that measures and records water pressure at regular intervals according to the passage of time.
