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

Tip Color

water-thin products, the chart at left can be used as

a guideline. If product is noticeably thicker than

No Tip

water, consult the Measurement of Concentration

Grey

Procedure below to achieve your desired water-to-

Black

product ratio. Because dilution can vary with water

temperature and pressure, actual dilution achieved

Beige

can only be ascertained by using the Measurement

Red

of Concentration Procedure. The clear, undrilled tip

White

is provided to permit drilling to size not listed should

you need a dilution ratio that falls between standard

Blue

tip sizes.

NOTE: A 1 GPM eductor is grey; a 4 GPM eductor

is yellow. Refer to parts diagram if unfamiliar with

Measurement of Concentration:

You can determine the dispensed water-to-product

Aqua

ratio for any metering tip size and product viscosity.

Purple

All that is required is to operate the primed dispenser

Pink

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.The water-to-product ratio is then calculated as follows:

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 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.
