Digital Flow Switch (Integrated display type) W A momentary steep pressure increase due the spread of pressure by closing a contactor such as a valve for an extremely short time while there is a flow. This pressure increase is known as water hammer or impact pressure.
Normal output Reversed output P_1 = A (A B)/4 n_1 = B + (A B)/4 A = Maximum pressure H_1 = (A B)/2 H_1 = (A B)/2 B = Minimum pressure In the OUT2 setting, the above P_1, n_1 and H_1 will be P_2, n_2 and H_2 respectively.

The piping on the IN side must have a straight section of piping whose length is 8 times the piping I.D. or more. If a straight section of piping is not installed, the accuracy varies by approximately 3% or more. : "Straight section" means a part of the piping without any bends or rapid changes in the cross sectional area.
