The density of Product B depends on the type of product. For ease of programming, the values of
water are included in the software. Therefore, if Product B is pure water or town water, no data
for Product B is required. Select either Pure Water or Town Water in menu C2.4.5 or C2.5.5
If Product B is not water, select Other in menu C2.4.5 or C2.5.5. To calculate the density of
Product B with changes in temperature, use the formula:
Product B = density of Product

3.2.10 Concentration flow
Concentration flow is calculated using the formula:
Concentration total is the accumulation of concentration flow over time
In all general concentration modes, use C2.2.3 or 2.3.3 to select which component in the
concentration to measure.
3.3 Suspensions
A suspension is a solid suspended in a carrier. The solid does not dissolve into the carrier and
the density does not change with temperature. Product B (carrier) can be set to water and so the
solid density should be entered as Product A.
