Easy to use menu structure Non-invasive No moving parts No pressure loss Hygienic flow measurement Easy and economical to install Measurement is independent of fluid conductivity and pressure No contact with medium ensures no risk of corrosion when measuring aggressive media. The Safsonic P portable flowmeter utilises ultrasonic technology for the accurate measurement of clean or opaque liquids in full pipes. The principle of measurement, Ultrasonic Time Difference Correlation, more commonly known as Transit Time or Time of Flight, is based on the theory that sound waves are affected by a flowing medium. Measurements are taken by penetrating the pipe with an ultrasound signal by means of two ultrasonic transducers, each having a turn to act as a transmitter and receiver. The transit time of the sound waves in both upstream and downstream directions of the flow are monitored with the resulting time difference being directly proportional to the flow velocity. This process is controlled and closely monitored by the hand held, microprocessor based display unit which returns the calculated data in user selected units of measurement. Where : ? is the sensor angle to the flow direction M is the number of the ultrasonic beam paths D is the pipe diameter Tup is the transit time of the beam from the upstream transducer to the downstream transducer Tdown is the transit time of the beam from the downstream transducer to the upstream transducer ?T=Tup –Tdown SAFSONIC P PORTABLE ULTRASONIC FLOWMETER KEY FEATURES APPLICATIONS SPECIFICATIONS SPECIFICATIONS The Safsonic P has been designed to meet the needs of any individual wishing to check the flow rate of liquids in most closed-pipe applications around the plant. The easy to use menu structure allows the user to obtain the required flow data within minutes.
