Total Alkalinity
AlkaSense®
Online measurement of total alkalinity provides significant advantages over intermittent manual testing. This includes maintaining optimal conditions for the Langelier Saturation Index, optimising alkalinity levels in swimming pool water. Historically, online total alkalinity measurement instruments have been costly and challenging to operate and maintain. However, AlkaSense® introduces an innovative approach by utilising an online conductivity sensor for measurement, which is both cost-effective and simple to maintain.
By utilising the onboard, pool specific control algorithms AlkaSense® can be used to automatically control acid or CO2 dosing to control the alkalinity or can control the ratio of CO2 to acid dosed when both are dosed together to automatically control the total alkalinity and the pH, simply and effectively in any pool or spa.
Cost of Ownership
The AlkaSense® system eliminates the need for sensor replacement, calibration, and routine cleaning, as the acid titration process inherently maintains sensor cleanliness. The primary ongoing costs are associated with the acid used and the semi-annual maintenance. Consequently, the overall cost of owning an AlkaSense® unit is comparatively low, especially when measured against alternative technologies.
key benefits
- Eliminates the need for calibration
- Provides stable and reliable measurements for improved process control
- Suitable for a wide range of pools and spas
- Maintenance is required only once every six months
- Utilises a straightforward and robust conductivity measurement method, as opposed to pH measurement
Options
AlkaSense® is available as either a standalone device paired with an analyser/controller or as part of any of the AutoPool® and Autopool® 4.0 pool and spa controller range. It can also come equipped with full total alkalinity control options including changing the ration of dosed CO2 to acid to maintain a constant alkalinity….. no more hand dosing of acid!
