The Watersens automatic dosing system provides an easy to use touch-screen dosing system at a very low cost.
It can be used for private swimming pools with a water volume up to 250m3
It has simple and clear operation, whilst measuring and regulating the Chlorine and PH levels in your pool.
This is an automatic dosing system for indoor or outdoor pools.
It can be used for domestic or small commercial pools (the optional free chlorine probe should be used for commercial pools)
The system automatically monitors the level of chlorine and PH in the pool and adds the required amounts of chemicals to maintain the pool at the desired levels.
It has an easy to use touch screen control panel, which allows you to set the desired level and monitor the current levels of chlorine and PH in the pool.
The flow switch prevents the unit from dosing the pool when the pool circulation pump is turned off and there is no flow of water to the probes.
The Watersens is available as two models:-
Watersens pH/RX - stand alone dosing system, non internet enabled
Watersens NET pH/RX - internet enabled model
2. Watersens NET Features
The Watersens NET allows the user to look at the data from the pool in real time from your mobile device, allowing you to set notifications for set parameters. This data can be viewed for a 30 day period using the iPool app or web browser.
3. Optional Free Chlorine Probe
The Watersens pH/Rx model comes complete with probes to measure the chlorine and PH levels
The amount of chlorine in the pool is displayed in a mV reading on the screen.
By setting the desired mV value, the Watersens will add liquid chlorine to the pool to maintain the chlorine level at the desired value.
As an alternative to the redox probe for chlorine control, a free chlorine probe is available as an option
The free chlorine probe displays the amount of chlorine in ppm (parts per million) eg 1.2 ppm
The free chlorine probe is normally required for commercial pools

6. Chemical Bund Tanks
We recommend that you purchase two "bund" tanks
These allow the 20 and 25 litre containers of liquid chlorine and acid to simply be placed inside the bund tank
This makes it very easy to swap the containers when they are empty
The bund tank is designed to hold all of the 20 or 25 litres of pool chemical should the container leak or split.
The bund tank then prevents the chemical from spreading over the floor of the pool plant room which could cause damage to the equipment in the plant room.
These bund tanks can be placed side by side or on top of each other when fixed to a wall.
The dimensions are 300mm wide x 440mm deep x 880mm high
