Method for checking flow rate of water in drying spacer of building e.g. multistoried building, involves comparing pressure determined at specific times to pressure determined at identical times, where times are measured by timers

摘要

The method involves attaching a pump (4) for compression at a feeding point (3) of a drying riser (2). An openable ball valve (10) is arranged at a discharging point (7) of the riser. Pressure of the riser at specific times in the feeding point is measured and stored. Pressure of the riser at an identical time at the discharging point is measured and stored. The pressure determined at the specific times are compared to the pressure determined at the identical times, where the specific and identical times are measured by timers (15, 16), which have a Bluetoothinterface.
