Application problems that appear to be Transducer Faults
• Leaky Valves will cause high zeros
• Entrained Air/gas will cause high energy levels and high zero
• Product coating on the inside of the tube will cause high/low density and high zero

The following faults have occurred (listed below with their symptoms):

Beware:
Application problems can cause similar symptoms, check this first!

Tube bore slightly eroded or corroded
• Density Low
• Frequency High
• Small Mass Flow Errors

Tube eroded or corroded through (fluid in housing)
• Tube will not start
• If fluid conductive - low resistance to ground

Open Circuit Drivers, Sensors, RTD’s and Strain Gauges
• Detectable with Ohm meter
