E0
No error.
Displays briefly after the
display of another error
message
None required. Measurement is valid.
E1
Low Signal - Poor ultrasonic
signal strength.
Broken cable. Flowcell problem.
Transducer problem. Electronic
failure.
Check transducer cable. See Flowcell
Problems on page 10-9 and Transducer
Problems on page 10-11. Check
programming and transducer spacing.
Contact the factory if problem persists.
E2
Sound Speed Error (Sound
speed is programmed
using the Program Menu
Pipe option. as described in
Chapter 4.)
Poor flow conditions.
Incorrect programming. Bad
transducer spacing.
Measurement is very different
from the programmed
sound speed.
Check sound speed against nominal
sound speed. See Flowcell Problems on
page 10-9 and Transducer Problems on
page 10-11. Check programming and
transducer spacing.
E3
Velocity Range - Velocity
exceeds programmed
limits. (Velocity limit is
programmed using the
Service Menu Error Limits
option as described in
Chapter 9.)
Programming error, poor flow
conditions, or bad transducer
spacing.
Make sure the maximum velocity range
is within the range listed in Table 3-1 on
page 3-4 for the pipe size and pressure.
Check programming and transducer
spacing. If programmed value is outside
of limit, change the limits as described in
Chapter 9 on page 9-32. See Flowcell
Problems on page 10-9 and Transducer
Problems on page 10-11.
E4
Signal
Quality
If too high - electronic failure. If
too low - flowcell, electrical
problem.
Check for source of electrical
interference. Check electronics with a test
flowcell.Check to see if the velocity is
above the maximum value. Check to see
if the pressure is above the minimum
required pressure for the pipe OD/WT. If
unit still fails to operate, contact the
factory.
E5
Amplitude Error
Excessive particles or liquid
present in fluid. A lot of second
phase present
See Flowcell Problems on page 10-9.
E6
Cycle skip, Acceleration
Poor flow conditions or bad
transducer spacing.
Check transducer spacing as
programmed and as set on pipe.See
Flowcell Problems on page 10-9 and
Transducer Problems on page 10-11.
E7
Analog Out Error
Under current output.
Check that output load is within
specification <550 ohm.
E16
High Signal
Entry of improper value in
Transducer or Pipe submenus.
Check values in Transducer and Pipe
submenus. Remove preamp.
E17
Equation Limit
(Steam equations only)
Process temperature and/or
pressure are outside valid
limits of Steam Equations for
mass flow.
Adjust the pressure reading to within the
range of 139.9685 kPa to 2242.9435 kPa, or
the temperature reading to within the
range of 373.1500K to 810.9278K.
E18
Supersaturated
(Steam equations only)
Process temperature is below
the saturation temperature of
steam for the process pressure.
Raise the system temperature or lower
the system pressure until all the water
vaporizes.
