Piping without Sampling System
When sample has a pressure of 1 to 150 kPa and a flow rate of 0.1 to 2.5 L/min, such sample can
be directly introduced into the measuring tank. Connect a Ø6 X Ø4 mm polyethylene tube to the
sample water inlet.
Connect a Ø22 X Ø15 mm flexible mesh-reinforced tube to the drain outlet from the measuring
tank. Install this tube so that no water entrapment is formed. Entrapment of water in the drain
tube may cause overflow from the measuring tank.
