Linear Range |
| Smart electronics corrects for lower flow down to a Reynolds number of 5,000. The Reynolds | |||||||||||
|
|
|
|
|
| number is calculated using the fluid’s actual temperature and pres- | |||||||
|
|
|
|
|
| sure monitored by the meter. Rangeability depends on the fluid, | |||||||
|
|
|
|
|
| process connections and pipe size. Consult factory for your applica- | |||||||
|
|
|
|
|
| tion. Velocity rangeability under ideal conditions is as follows: | |||||||
|
|
| Liquids 30:1 |
| 1 foot per second velocity minimum |
|
| ||||||
|
|
|
|
|
|
| 30 feet per second velocity maximum |
