FloSonex vortex flow meters are designed for accurate flow rate measurement of ultra-pure and ultra-aggressive liquids. The flow sensor consists of a solid flow tube and a removable PTFE or PVDF sensor. The flow tube is compatible with most processing liquids including DI water, hot (up to 160 °C), 95% sulfuric acid, phosphoric acid, SC1, SC2, “Piranha,” and many others. The flow tube is completely passive containing no moving parts. The only active components are the two ultrasonic transducers sealed within the sensors. The sensors are easily removed from the flow tube with a blade screwdriver. All repairs may be made without shutting the process down. Each FloSonex unit is permanently calibrated at the factory. Removal of the sensors does not affect calibration. In t e unlikely event of an electronics failure, calibration data may be downloaded to the new module.
