Tube Adjustment for Select Dosers We’ve had a number of customers in the past who were a little confused by the Tube Adjustment ratings on their peristaltic pump tubes for the Select Doser. So, we’ve put together both this article and the accompanying video to explain what the tube adjustment is and how to change it on your Select Doser.
How to choose the right one to suit your water dosing task and your Select doser type. There are a lot of farmers across Australia with a need to add something into the drinking water for their Livestock. Most of these applications have one thing in common: The need for dosing to be automatically adjusted in proportion to the water flow. When we first launched the Select Doser in Australia about 16 years ago, there were only a couple of options available for Water Flow measurement. We had sensors in our range to measure very small and very high flows, but very little to cover the middle of the range that people encounter on farm. This meant that our customers in the early years could use the Select Doser for precision applications (such as a Poultry Shed, or Weaners on a pig farm) or Farm-wide applications (such as Water treatment with Chlorine or Peroxide), but didn’t have a good solution for intermediate applications (Dosing a decent sized group of cattle independently, or multiple sheds on a piggery). As you’ll see below, things have changed. We now have a range of flow measurement devices to cover, not just any flow situation, but also dramatic differences in source water quality.
Of the many steps Australian farmers take to improve the biosecurity of their farms, one significant threat is often not taken seriously enough. The provision of safe, clean drinking water is hugely important to the prosperity of any livestock farm. The costs, in terms of productivity losses and mortality, of not doing so can be astronomical.
When we talk about untreated water, we are really talking about water from a large number of possible sources, including: Bore Water Channel/River Water Rain Water Dam Water
Water Pressure Definition and how to find it Water Pressure is the force of the water flowing through the line. In all water lines, this force is essential to ensure the water reaches its destination.
Tube changing with Select Dosers…why does it matter? Many types of dosing pumps just can’t handle the delivery of aggressive chemicals such as acids or chlorine. The corrosive effect of these products on lesser plastic and metal components makes them a difficult job to handle. Due to this, peristaltic pumps like the Select Doser are the obvious choice to dose these more chemically aggressive products into water.
Flow Rate Definition and how to find it Flow rate literally means the speed of the water flowing through the line. It is a volumetric measurement, usually expressed in litres per hour. It is an absolutely crucial number because each type of dosing machine can only dose a finite amount of an additive per hour.
Water Consumption Definition and how to find it Water Consumption is the amount of water used by the herd/flock (or a smaller group) in a given day. It is a volumetric measurement, best expressed in litres per day. It is often a very useful number in livestock dosing applications because it can be used to provide a rough FLOW RATE.
The Golden Numbers of Water Dosing How to make the right choice of doser While it is possible to just buy a dosing machine and hope it works, there are a 3 “Golden Numbers” you should work out in advance to make sure you get the right doser for your needs. These figures are crucial in working out if any dosing pump will work on your farm (not just the machines we sell). So even if you are looking at a Dosatron, Chemilizer, or some other option, make sure to work out the following before going ahead with a purchase. The Golden Numbers are:
Can you use an automated dosing system on your farm? In Australia, some people still believe that water dosing systems (such as the Dostatron, Gator, Select Doser, etc.) can only be used on large, intensive operations such as pig and poultry farms, where livestock are kept in fairly close quarters. This is not the case.
