> Tick checkbox in case of sensor failure.
Velocity > Tick checkbox to activate replacement function, if current measurement value exceeds or
falls below the defined limit for flow velocity.
> Enter velocity limit value.
less = replacement function is activated if current measurement value falls below the defined
limit value.
greater = replacement function is activated if current measurement value exceeds the defined
limit value.
