  • Page 7: Operational

    electronic option G0/H0/I0/K0/L0 OPERATIONAL 2.1. General  The flow rate/totaliser may only be operated by personnel who are authorized and trained by the operator of the facility. All instructions in this manual are to be observed.  Take careful notice of the "Safety rules, instructions and precautionary measures" in the front of this manual.
  • Page 8 electronic option G0/H0/I0/K0/L0 2.3. OPERATOR INFORMATION AND FUNCTIONS In general, the flow rate/totaliser will always act at Operator level. The information displayed is dependent upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the flow rate/totaliser in the background, whichever screen refresh rate setting is chosen. After pressing a key, the display will be updated very quickly during a 30 second period, after which it will slow-down again.

  • Page 13: Total

    electronic option G0/H0/I0/K0/L0 3.2.3. EXPLANATION OF SETUP-FUNCTIONS 1 - TOTAL MEASUREMENT UNIT SETUP - 11 determines the measurement unit for total, accumulated total and pulse output. The following units can be selected: L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit). Alteration of the measurement unit will have consequences for operator and SETUP-level values.

  • Page 14: Flow Rate

    electronic option G0/H0/I0/K0/L0 2 – FLOW RATE The settings for total and flow rate are entirely separate. In this way, different units of measurement can be used for each e.g. cubic meters for total and liters for flow rate. The display update time for flow rate is one second or more. Note: these settings also influence the analog output.

  • Page 15: Display

    electronic option G0/H0/I0/K0/L0 3 - DISPLAY FUNCTION The large 17mm digits can be set to display total or flow rate. When "total" is selected, both total and flow rate are displayed simultaneously. When "flow rate" is selected, only flow rate will be displayed with it’s measuring unit while total will be displayed after pressing SELECT.

  • Page 16: Flowmeter

    electronic option G0/H0/I0/K0/L0 5 - FLOWMETER SIGNAL The flow rate/totaliser is able to handle several types of input signal. The type of flowmeter pickup / signal is selected with SETUP 51. Note: The selections "active pulse" offers a detection level of 50% of the supply voltage.

  • Page 17: Linearisation

    electronic option G0/H0/I0/K0/L0 6 - LINEARISATION The linearization function is available to approach the real flow curve better as with the general K-factor (KF0) entered with setup 14 and 24. This to obtain a more accurate flow rate, total and accumulated total as well as the analog and pulse output at any flowmeter frequency.

  • Page 18: Analog Output

    electronic option G0/H0/I0/K0/L0 7 - ANALOG OUTPUT A linear analog 4-20 mA signal is generated according to the flow rate with a 10 bits resolution. The settings for flow rate (SETUP - 2) influence the analog output directly. The relationship between rate and analog output is set with the following functions: DISABLE / ENABLE The analog output can be disabled.

  • Page 19: Analog Output (Continued)

    electronic option G0/H0/I0/K0/L0 7 - ANALOG OUTPUT (CONTINUED) FILTER This function is used to stabilize the analog output signal. The output value is updated every 0.1 second. With the help of this digital filter a more stable but less precise reading can be obtained. The filter principal is based on three input values: the filter level (01-99), the last analog output value and the last average value.

  • Page 20: Pulse Output

    electronic option G0/H0/I0/K0/L0 8 - PULSE OUTPUT One transistor or mechanic relay output is available as scaled pulse output according to the accumulated total. PERIOD TIME The period time determines the time that the transistor or relay will be switched; PULSE OUTPUT in other words the pulse length.
