Basic Specifications
| Flow rate
measurement Q = fUP where Q is the flow rate, f is a frequency, U is the user-readable unit of flow(x1, x60, x3600), P is the pulse conversion value |
|
| Flow indication | 0~9999: Red LED,
Character 8mm High, with
zero-suppress function. Decimal point: Programmable form the front key Over-range indication:Display blank: Changeover to be put on or off. |
| Display cycle | Selectable from the front key. 100ms, 400ms, 1s, 2s, 5s |
| Moving averaging | Selectable from the front key. 1, 2, 3, 4, 8, 16-time |
| Pulse conversion value | Selectable from the
front key, from 1x10-6 to
9999 |
| Time base | Selectable from the front key. Seconds, minutes, or hours |
| Accuracy | ± (0.05％+1digit) |
| Flow totalize
measurement The meter displays calculation values which is multiplied numbers of input pulse by the K-factor. Any point can be assigned to initial of total value and be programmed anywhere in the range of the meter. |
|
| Flow indication | 0~99999: Green LED,
Character 8mm High, with
zero-suppress function. 5 or 10 significant digit: Programmable form the front key Over-range indication:Display blank: Changeover to be put on or off. |
| Pulse factor | Programmable Pulse
factor from the front panel. From
1x10-6 to 999,999
pulses/unit. P.O output is synchronized to input pulse when exceeding 1. |
| Primary integrated value | from 0 to 99999, programmable from the front key |
| Display cycle | approx. 0.1s |
| SIG display | Light-up when inputting the signal |
