7.3.1.9. Mass +
See section 7.3.1.6, for the aggregate mass flow in the positive direction.
7.3.1.10. Mass -
See section 7.3.1.7, for the aggregate mass flow in the reverse direction.
7.3.1.11. Temperature
The temperature reading is only available if a thermometer is included in the meter configuration. The reading
sensitivity is 0.1 °C.
7.3.1.12. Density
The fluid density readings are available provided a thermometer has been installed.
7.3.1.13. Sound propagation velocity
Velocity of the acoustic signal propagating in the measured fluid.
7.3.1.14. Fluid flow velocity
Velocity of the fluid passing through the sensor flange.
7.3.1.15. Start of the measurement period
The calendar date, hour and minute when the measurement period commenced (the last resetting of the
aggregate flow data).
7.3.1.16. Duration of the measurement period
The length of the period (in hours, minutes and seconds) from the measurement start (see section 7.3.1.15)
during which the flow meter continuously performed the flow rate measurements.
7.3.1.17. Duration of failure condition
The total duration of the period(s) (in hours, minutes and seconds) from the measurement start during which the
meter was energised but could not perform measurements due to a failure condition.
7.3.1.18. Power failure period
The total duration of the period(s) (in hours, minutes and seconds) from the measurement start during which the
meter was not energised.
7.3.1.19. Date
The display shows the actual calendar date.
7.3.1.20. Time
The display shows the actual time of the day.
7.3.2. Parameter setting mode
When selecting the parameter setting mode (see section 7.3.1), the operator will be requested to enter a four-
digit password.
7.3.2.1. Password
The first display line will read
PASSWORD
and the first digit position on the second line will display 0. Depress push-button T3 repeatedly to increase the
number by 1 at a time (after 9 will follow 0 again). Select the correct number at the first digit position and then
depress push-button T2 to move to the second digit position and repeat the number setting procedure with push-
button T3. Progress to the third and fourth digit positions and enter the correct password – a combination of four
numbers (see the schematic diagram in Fig. 7.3.3, page 32).
Confirm the entry of the correct password by depressing push-button T4. Provided the password entered is
correct, the system will proceed to the language selection block. In the case of an incorrect password the system
will request a new password entry. After three consecutive entries of incorrect passwords the system will switch
over to the data display mode and will not permit further entry into the parameter
setting mode. A new attempt at the password entry is only possible after system de-energising and repeated
switching on of the power supply.
