SensoTech’s LiquiSonic inline analyzer measures cleaner concentrations directly in a cleaning bath to enable values to be maintained within predefined limits. The system consists of as many as four stainless steel sensors and one controller that are digitally connected. The controller manages and visualizes measurement data from the sensors that is based on sonic velocity measurement. Automatic process control systems then can be integrated. The ultrasonic measurement process can deal with extreme processing conditions such as temperatures between -100°C (-150°F) and +200°C (375°F), and process pressures of a few mbar to 500 bar (7,000 psi).
