Pressure Loss
According to OIML R49 the maximum pressure loss must not exceed 0.63 bar in range Q
1
up to and incl. Q
3
and max 1.0 bar at Q
4
respectively. The pressure loss is without anti-pollution check valve.
The pressure loss in a sensor increases with the square of the flow and can be stated as:
p
kv
Q
where:
Q
= volume flow rate [m³/h]
kv
= volume flow rate at 1 bar pressure loss [m³/h]
p
= pressure loss [bar]
