AquaSense Swimming Pool Controller and Spa Controller

Swimming Pools and Spas use chlorine as a disinfectant and so use chlorine analysers and pH meters to control the amount of chlorine that gets dosed. The AquaSense Pool and Spa Controller measures the pools chlorine levels and then controls the chlorine and pH levels by controlling the chemical dosing. The AquaSense advanced chlorine controllers offer bufferless and reagentless operation.

Pi does not sell the AquaSense range of pool controllers directly but badges them for pool companies who resell them to the end customers. Are you interested in becoming an AquaSense reseller?

Pool and Spa Disinfection and Chlorine Controller and pH Controller

Key Benefits

• Stable and reliable Residual Chlorine and pH measurement
• Low purchase cost
• Low cost of ownership
• SMS text alarms
• Remote Access via Internet
• Automatic dosing control
• Other inputs to Datalog and Alarm
• Pool and Spa Chlorine Controller

The sensors used by Pi in our Pool and Spa Controller are the same sensors that we use in our water treatment analysers, meaning that you get the highest quality controller at the best price.

In the modern municipal swimming pool or spa or a swimming pool or spa operated privately in the leisure industry a Pool Controller or a Spa Controller must offer advanced communication and control options. With the AquaSense Pool and Spa Controller it is possible to interface and control the Chlorine Analyser Monitor remotely over the internet, enabling data, alarms and setup information to be sent direct to your computer via GSM/GPRS modem or via a TCP/IP Local Area Network (LAN). Purchase costs for an AquaSense Pool Controller are less than, or comparable to, its competitors, but offer far greater functionality.

In many Spas and Pools the disinfection control is managed by a service provider who is usually off site. The swimming pool and spa disinfection controller provides remote access via mobile phone texts and via the internet using GPRS, thereby saving time and money in not having to attend site unless strictly necessary.

The AquaSense swimming pool analyser is on site in many pools and spas around the world. It is the residual chlorine controller of choice for many because of its superior chlorine measurement and spa chlorine control. Spas offer a more difficult chlorine control problem because of the higher temperature and the low volume of water. The AquaSense Pool and Spa Controller offers far superior control in spas.

Introduction

The AquaSense range of pool controllers has been designed to three criteria:-

• Improved Safety - better sensors lead to better process control which leads to less variation in chlorine residuals even with highly variable bathing load.
• Improved Control - better process control leads to reduced chemical usage, lower costs and an improved bathing experience.
• Reduced Costs - lower chemical costs, less expensive controllers, hugely reduced electrical usage costs are just a few of the ways that the AquaSense can save you money which can pay for a new controller in just a few months.

Sensors

Traditionally pool chemistry has been controlled by using ORP (Redox) or Residual Chlorine Sensors. The quality of the sensors has a huge effect on the ability of the controller to maintain a safe and pleasant bathing water. The sensors used in AquaSense controllers are the best available in the world today and are exactly the same sensors that are used to monitor and control drinking water in many municipal drinking water plants worldwide.

Chlorine Sensors

Three sensors are available to measure; free chlorine, total chlorine, or chlorine in the presence of cyanuric acid. All of these sensors have a long life (10 years) with reduced maintenance and calibration requirements. They are very high quality and very easy to own. Being able to accurately measure the chlorine and respond to varying bathing loads means that pools and spas can operate at lower chlorine levels, reducing the formation of unpleasant combined chlorines and reducing the chemical usage, thereby reducing costs, reducing emissions, all while providing a better bathing experience.

pH and ORP Sensors

The pH and ORP sensors are made specifically for the AquaSense controllers and come with either a one or two year warranty. These AquaSense pH and ORP sensors are also exactly the same as those used in the water industry and are not the low cost, low quality sensors that are often supplied into the Pool Industry.

Remote Access & Text Alarms

More and more pools are maintained by service professionals that are based off-site and the ability of these engineers to respond quickly and effectively to a process upset at a pool depends on them getting the correct information as soon as possible. The CRIUS^®AquaSense and the CRATOS AquaSense can come equipped with their own integral GSM modem. This in turn allows anyone with the appropriate security level to receive text alarms relating to the chemistry in the pool or spa and also allows them to log in to the controller over the internet and perform almost any action that they could do if they were standing in front of the instrument.(For an online demonstration of this please go to www.processinstruments.net/products/remote-accessdemo.php)

The highly sophisticated pro-active text alarms and remote access capability of the CRIUS^® AquaSense and CRATOS AquaSense, means that:-

• Improved Communication - the right people know as soon as something happens.
• Improved Control - your expert is in your pool room no matter where they are.
• Less Time to Fix Problems - the time taken to fix any problems is greatly reduced.
• Reduced Costs - time, cost and emissions are reduced.

Building Management Systems

Many leisure facilities are now fitted with sophisticated BMS (Building Management Systems) and all three Pool and Spa controllers are able to communicate directly to the BMS whatever system it might be. Each of the Pool and Spa controllers from Pi can come equipped with a range of communication protocols including LAN, Profibus, Modbus and more traditional analogue and digital outputs. Save Money and the Planet! Most pool recirculating pumps are over specified for the duty required and as such there is scope to turn them down and save considerable amounts of money on the electricity usage. Whenever you save electricity you are reducing the CO₂ emissions and carbon footprint of your pool and spa and for many organisation reducing CO₂ emissions is a significant factor in choosing which equipmrnt to purchase. It might not save the planet but it is a good start! In order to turn down the pool recirculating pump the pump motor must be fitted with an invertor. The question then arises - on what basis do we turn the motor down?

Each pool has a minimum turnover set by the manufacturer or consultant at the time of installation. The CRIUS^® or CRATOS AquaSense allows the user to turn down the recirculating pump during periods of non pool use (overnight) to the minimum level. While the pool is being used the recirculating pump motor is set based on chlorine demand which is proportional to bathing load. This ability to control the recirculating pump based on chlorine demand means that pool operators can save significant sums of money on electricity during the times when electricity costs the most.
