Display and decimal point functions
Flow-rate LCD
The flow unit is labelled by the manufacturer. Decimal-point positions depend on the displayed range:
| Range | Decimal point |
|---|---|
| 0–1.999 | D3 |
| 2.0–19.99 | D2 |
| 20.0–199.9 | D1 |
| 200–1999 | None |
Flow-rate and totalizer LCD
The upper row shows the accumulated total with 10 digits; the lower row shows flow rate with 8 digits. The flow unit appears on the LCD. The diagram identifies the D1, D2 and D3 decimal-point positions.
Display choices are no LCD, flow-rate LCD, flow-rate LCD with blue backlight, or flow-rate and totalizer LCD with blue backlight.
Dimension drawings include both display versions, all side, front and mounting views, millimetres and inches, and the ±1.0 mm tolerance.
Specify the actual gas and operating conditions for calibration review.
