Azbil Corporation No. SS2-MTG300-0100 - 3 - Flow unit Volume flow:m3, L, cm3, G (gallon), mG, kG, B (barrel), IG (imperial gallon), mIG, kIG Mass flow: t, kg, g, lb Time: d, h, min., s Display Display: LCD Main display: 7-segment, 8 digits Sub display: 16 digits, 2 lines Display contents: Simultaneously displays % flow rate, Actual flow rate (eng. unit) and Totalized value. Data setting Operation by four key switches Damping Adjustable between 0.5 and 199.9 seconds. Low flow cutoff Adjustable between 0 and 10% of setting range. Below selected value, output is driven to the zero flow rate signal level. Dropout Adjustable between 0 and 10% of setting range. Below selected value, pulse output is cut. Electrode status diagnostic Detect empty pipe condition or scale on electrode condition by monitoring flow rate signal. Once the flow rate signal fluctuates over a certain threshold, the device judges that the detector is empty or scale appears on the electrode. The Electrode status diagnostic function makes the analog output and pulse output to the values as selected in the below "Electrode status output mode" table. The display alternately shows the output values selected and "EMPTY OR SCALE ON ELECTRODE". There are five threshold levels to meet an environment where the device is installed. Set an appropriate threshold level from below. SENSITIVITY HIGH SENSITIVITY MID SENSITIVITY LOW SENSITIVITY LL SENSITIVITY LLL Default setting: OFF Operating condition: The following conditions must be met when using the electrode status diagnostic function. . Diameter: 10mm or larger . Electric conductivity of fluid: 30 ..S/cm or greater . Grounding: Grounding resistance must be less than 100.. . The noise level must be over the set threshold when the pipe is empty. . The noise level must be under the set threshold when the process fluid flows in the detector. “Electrode status output mode” table” Output/Display Parameter selection in the “Electrode status output mode” OFF ZERO HOLD Analog 4 . 20mA output Output values as the meter measures. Analog output is fixed to 0% (4mA). Analog output is held at its last good value. Pulse output Output values as the meter measures. Pulse output is fixed to 0 (does not generate pulses). Pulse output is held at its present state. Display Display the value as it measures. Flashes the message 0% and “Empty or scale on electrode” alternately (when % flow rate is specified for the main display). Flashes the message 0.000 RATE and “Empty or scale on electrode” alternately (when actual flow rate is specified for the main display). Flashes the message XXXXXXXX (totalized value at setup) and “Empty or scale on electrode” alternately (when totalized value is specified for the main display). Flashes the values at its last good values and a message of “Empty or scale on electrode” alternately. 4 11
