Chronoflo 2


The ChronoFLO transit time flow meter can measure instantaneous flow rates in your flow-carrying pipes. This instrument uses a fully coded signal correlation process to obtain stable measurements even under the most challenging conditions. To cover a wide range of applications in any sector, only one signal processing unit is used. This configuration is supplied with two sensors and a mounting rail that fits a wide range of diameters.



  • Diagnosis of drinking water and wastewater networks
  • Sectorisation (looking for leaks)
  • Checking existing flow meters
  • Calibration of lift pumps
  • Volume quantification.
