  • Page 19: Display Of Reset Integration / Accumulated Total Or Instantaneous Flow Rate

    (e.g. meter factor, decimal point position.) The signal input from flowmeter is detected in EL0137 to display the flow rate. The displayed value is updated according to the update cycle of the selected display. After the key operation, the displayed value is updated eight times every second and the value will return to the setting value selected by parameter confirmation mode (3.1: update cycle)
