Verify Vs is correct for Liquid and Temperature.
q
Verify Valc is Greater Than 30.
q
Verify Vaer is Less Than 10 when flowing.
q
Check Signal Graph to be acceptable. See reference graphs below.
q
For 100 Universal Transducers verify “VfMax” is significantly higher than maximum
Flow Rate of application.
q
Set “Hi Flow” at 90% VfMax; Ensure it is higher than Max Application Flow Rate.
q
Set “Lo Flow” at –10% VfMax. (For unidirectional flow applications only!)
