Metering Tip Selection:
The final concentration of the dispensed solution
is related to both the size of the metering tip
opening and the viscosity of the liquid being
siphoned. For water-thin products, the chart at
right 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. Be-
cause dilution can vary with water temperature
and pressure, actual dilution achieved can only
be ascertained by using the Measurement 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 4 LPM eductor is grey; a 16 LPM eductor
is yellow. Refer to parts diagram if unfamiliar with
names of system components.
Measurement of Concentration:
You can determine the dispensed water-to-prod-
uct 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. The water-to-product ratio is then calculated
as follows:
Dilution Ratio (X:1) where X = Amount of Mixed Solution — Amount of Concentrate Drawn
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 different 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.
