START-UP
q Ensure pipe is FULL (flowing or not).
q Select “Install Complete?”…..INSTALL to Invoke “Initial Makeup” routine.
q Verify “Measured Vs” is accurate for liquid type & temperature (Consult Vs Database)
q Set Zero appropriately (AutoZero or ZeroMatic for Reflect, Actual Zero or ReversaMatic
for Direct).
q After completion of Zeroing, access Flow Display by pressing <MENU> key.
q Use <UP/Down Arrows> to scroll through available displays.
q Avoid mounting on pipe seams.
q Connect “UP” Cable to “Upstream Transducer” (closest to source of flow) and vice versa.
q 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!)
q Set “Lo Flow” at 10% Greater Than Maximum Negative Flow (Bi-Directional Applica-
tions).
DIAGNOSTIC/PERFORMANCE VERIFICATION
2.12.2 OPTIMIZATION/CORRECTION OF PROBLEMS
Incorrect “Measured Vs”
q Verify actual pipe (outside) diameter matches meter programming.
q Verify actual Wall Thickness matches meter programming.
q Verify transducer Type and Size matches meter programming.
q Verify transducer mount method, and spacing positions (indices) match meter program-
ming.
q Check actual transducer spacing matches “Ltn” dimension.
