ALPINE Liquid Innoculant Injection Liquid Kit Example
Find the video describing the operation of ALPINE’s liquid injection kit, injecting innoculant into a liquid fertilizer kit.
Note the good use of a isolated feed flow indicator on the injector pump to indicate that the injector is working properly.

Isolated Feed Flow Indicators
Isolated Feed Flow Indicator Columns
The isolated feed columns are used to monitor multiple single feed lines. For example, monitoring individual lines coming out of a squeeze pump.
Isolated Feed Flow Indicators come in two different columns sizes, broken down by recommended flow ranges:
Low Flow Column: 0.05 – 0.65 us gpm flow rates
Standard Flow Column: 0.07 – 2.70 us gpm flow rates
Wilger Visual Ball Flow Indicator Benefits
ORS Metering Orifices
O-ring seal metering orifices are accurate and large enough to make them easy to handle, so switching rates is easy.
Custom hole-size orifices and ISO-color coded orifices are available to match any rate required for in-furrow applications.
Best in Class Clarity
Wilger visual ball flow indicators come standard with the best materials available on the market to make an ultra-clear, UV & chemically resistant flow indicator.
360° Range of Motion
All O-ring sealed fittings can be spun 360° without fear of leaking of pulling out.
This makes installation easy as the fittings pivot to where you need them to point.
Chemical Resistance
Find the below plastic compatibility chart, which compares TPX to other commonly used clear plastics like PVC.
TPX outperforms all other clear polymers in chemical resistance, cold/hot temperature rating, and more.
TPX & Other Plastic Compatibility
The above reference chart and information is not made by Wilger; and as such, cannot be guaranteed for accuracy.
All of the Flow Indicator and O-Ring Seal (ORS) product lines are made specifically for chemical resistance.
With all fittings made out of glass-reinforced polypropylene with VITON® O-ring options, there isn’t much that these flow indicators can’t handle.

As a pro-tip for assembling a flow indicator system, using a small amount of lubricant, such as liquid silicone on the o-ring when fitting any ORS components together makes it a breeze.
The clear plastic used to make all Wilger visual ball flow indicator columns is very special. It provides the greatest amount of chemical resistance, while maintaining the best clarity at the same time.
Over time, as with all plastic, it deteriorates in long term exposure to UV (such as the sun). To combat this and to extend the life of the flow indicator columns, Wilger uses a UV inhibitor, but to further extend the clarity of the plastic flow indicator columns, it is best to cover them up whenever in use.
Having a flow indicator column covered from UV will significantly increase the lifespan and clarity of the plastic.
Since there are three different sized flow indicator columns to fit a number of applications, it is important to be able to tell them apart, as from a distance, they look very similar.
With a similar outward appearance, use the below as a guide to differentiate between them:
[Pictures to be added for visual representation]
STANDARD FLOW COLUMNS – On the flow indicator front and back, there is a small logo plate that has a WILGER logo. On the standard flow column, the WILGER logo is on the front and back of the column.
LOW FLOW COLUMNS – On the flow indicator front and back, there is a small logo plate that has a WILGER logo on one side, and a LOW FLOW label on the back side.
ULTRA LOW FLOW COLUMNS – The inside of the column for ultra low flow columns are considerably narrower than the other series of columns, and do not have a stepped interior wall inside the column.
