The pressure loss in a flow sensor is indicated as continuous flow q
p
.
Actual pressure loss at the indicated flow can be calculated using the Kv value, which
indicates flow at 1 bar differential pressure:
Δp Pressure loss in bar
Q = Flow in m

LCD
The WSx8 has a large, easy-to-read LCD with 8 digits to display different values (e.g. energy
or flow). The dynamic display enables users to identify positive flow at a glance. Icons for
previous year values and previous month values support the easy-to-understand display
concept.
