A derived measurement; the sum of two similar measurements
Example: Temperature T1 + Temperature T2 |
8900 |
* % Reject
|
A derived measurement based on two conductivity values. In an R.O. system, this measurement shows how much of the impurities in the water have been removed. If the incoming water measures 100 µS, and the outgoing water measures 5 µS, then 95% of the impurities were rejected. |

8900 |
| * % Passage |
A derived measurement based on two conductivity values. % Passage is how much of the impurities in the water have not been removed. If the incoming water measures 100 µS, and the outgoing water measures 5 µS, then 5% of the impurities were allowed to pass.

* Recovery A,
* Recovery B,
* Recovery C |
Recovery is a derived measurement of the ratio between the inlet flow rate and the outlet flow rate of a Reverse Osmosis (R.O.) system. If the R.O. system has water coming in at 10 GPM and water going out at 1 GPM, then 10% of the water is being recovered. The 8900 provides three variations of the recovery formula to accommodate variations in the location of the two flow sensors.

* Power 2,
* Power 4 |
Power 2 and Power 4 are measurements that use a derived differential temperature measurement and a primary flow rate measurement to calculate the amount of thermal energy ( BTU ) gained or transferred in a process. If equipped with 6 input channels, the 8900 can provide two power measurements, Power 2, Power 4.
