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 left can be used as
a guideline. If product is noticeably thicker than
water, consult the Measurement 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 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 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 concen-
trate 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
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.
