Model 8037 Sodium monitor – wall-mounted
Installation
▲
ABB Sodium monitors are normally located inside the Water Treatment
Plant on a rack – preferably in an air-conditioned room.
▲
Samples are normally at ambient temperatures so sample cooling should
not be necessary (even the polishing plant will be below 55
°
C).
▲
Fit a needle valve upstream to control the sample flow within required
limits.
▲
Conveniently site the standard solution bottles on the top of the liquid
handling section of the monitor.
