Pi is pleased to welcome a new partner from China’s swimming pool industry. Pi’s high quality swimming pool controller ‘AquaSense’ has been chosen by Shanghai Poolice Water Treatment Technology Co., Ltd. (Poolice) to be their main product offer for pool control due to several benefits which the instrument can offer


  • Saves money by controlling pool recirculating pumps based on chlorine demand
  • Eliminates bacteriological growths in pools and spas through better chlorine control
  • Optimises the chemical usage to minimise chlorine in the pool
  • Provides remote access via the Internet

Poolice is a new company in Shanghai, which is focusing on pool water quality monitoring and treatment solutions. According to the company itself it is committed to completely transforming the current poor water quality in China’s pool industry by integrating the world’s latest and best pool technologies. Michael Zhang, a founder of the company, visited Pi’s manufacturing centre in Burnley in the UK, to receive full training on Pi’s advanced swimming pool controller AquaSense. During his visit he was particularly impressed with a trip to a local pool that is using the AquaSense, when he discovered that perfect control is being maintained in a busy pool at 0.7 ppm chlorine and in a busy spa at 1.5 ppm chlorine.

CRIUS OzoSense in China
Ozone monitor with three ozone sensors in Shanghai

Ozone dosing control is notoriously difficult to do successfully due to the short residence times and extremely low levels (sub ppm).

Shanghai Limpion in China installed a multi-parameter ozone monitor from Process Instruments in March 2013 and since then have had nothing but praise for the online residual ozone meter.

Shanghai Limpion installed the ozone controller in June 2013 to provide PID control back to an ozone generator to maintain a steady low level in the process water ensuring effective disinfection.

After six months of trouble free operation Shanghai Limpion are pleased with their choice of analyser made by comparing the functionality (including the capability of up to six sensors with full PID and remote access), versus cost. Jason from Shanghai Limpion said “We are very happy with the ozone analyser from Pi. The control is very good”.
