1) An lf turbine meter alarm (blade failure) has occurred turbN lf.
2.6.2.3. ULTRASONIC NON ACCOUNTABLE ALARMS
If the Model 2000 is set-up for use with an Ultrasonic Meter then the following alarm types can also occur:-
1) Meter path 1 efficiency is below pre-set % limit usN eff.1%.
2) Meter path 2 efficiency is below pre-set % limit usN eff.2%.
3) Meter path 3 efficiency is below pre-set % limit usN eff.3%.
4) Meter path 4 efficiency is below pre-set % limit usN eff.4%.
5) Meter path 5 efficiency is below pre-set % limit usN eff.5%.
6) Meter has sent a path Status alarm
7) Meter is configured for incorrect units.
2.6.2.4. DIFFERENTIAL PRESSURE NON ACCOUNTABLE ALARMS
If the Model 2000 is set-up for use with Differential pressure measurement across an orifice plate then the following alarm
types can also occur, All differential pressure alarms will be indicated without sign for the positive or single direction and
prefixed by a –ve sign for alarms on transmitters when the flow is in a negative or reverse direction:-
1) High range dp sensor 1 is above the value of dphi.N hi.
2) High range dp sensor 1 is below the value of dphi.N lo.
NOTE In all cases above 1) to 2) the numeric character could be 1, 2 or 3 depending upon the number of
selected multiple transmitters.
NOTE In all cases above the character N will refer to the stream number 1, 2 or 3.
2.6.2.5. DENSITY ACCOUNTABLE ALARMS
If the Model 2000 is set-up for use with a periodic measured Density input then the following alarm types can also occur:-
1) Density value is above the High alarm limit densN hi.
2) Density value is below the Low alarm limit densN lo.
3) Density values are in deviation.
4) Relative Density values are in deviation.
2.6.2.6. SMART INDEX NON ACCOUNTABLE ALARMS
Alarm Related to the use of the Model 2000 with a Smart Index.
1) Smart Index Reset type 1
2) Smart Index Reset type 2

4) Smart Index Ram fail type 3
5) Smart Index Magnetic wire failure
6) Smart Index Namur Interface failure
7) Smart Index EEPROM Failure
8) Oil Level Alarm (Status Input)
NOTE In all cases above the character N will refer to the stream number 1, 2 or 3.
2.6.2.7. CORIOLIS METER NON ACCOUNTABLE ALARMS
1) Deviation Alarm between Serial Flow Value and Pulse Input Value
2.6.2.8. GRAB SAMPLER NON ACCOUNTABLE ALARMS
1) Grab Sampler Production period has expired.
2) Grab Sampler Can fill warning.
3) Grab Sampler Deviation Alarm. Deviation between the actual fill level and the estimated/calculated fill
level
4) Grab Sampler Sample rate alarm.
