Metering Tip Selection:
The fi nal concentration of the dispensed solution is re-
lated to both the size of the metering tip opening and
the viscosity of the liquid being siphoned. For water-thin
products, the chart at left can be used as a guideline. If
product is noticeably thicker than water, consult the Mea-
surement of Concentration Procedure below to achieve
your desired water-to-product ratio. Because dilution can
vary with water temperature and pressure, actual dilution
achieved can only be ascertained by using the Measure-
ment of Concentration Procedure. The clear, undrilled tip
is provided to permit drilling to size not listed should you
need a dilution ratio that falls between standard tip sizes.
NOTE: A 1 GPM eductor is grey; a 4 GPM eductor is yellow.
Refer to parts diagram if unfamiliar with names of system
components.
Measurement of Concentration:
You can determine the dispensed water-to-product
ratio for any metering tip size and product viscosity.
All that is required is to operate the primed dispenser
for a minute or so and note two things: the amount of
dispensed solution, and the amount of concentrate used
in preparation of the solution dispensed.
Dilution Ratio (X:1) where X = Amount of Mixed Solution — Amount of Concentrate Drawn
Dilution Ratio, then, equals X parts water to one part concentrate (X:1). If the test does not yield the desired ratio, choose a diff erent tip
and repeat the test. Alternative methods to this test are 1) pH (using litmus paper), and 2) titration. Contact your concentrate supplier
for further information on these alternative methods and the materials required to perform them.
