Series SX3 Ultrasonic Flowmeter Detectors employ a clamp-on type design for permanent use based on transit time measuring method. These detectors are ideal for clean liquids containing no air bubbles such as pure water. The easy-to-use compact and lightweight design is intended for integration into mechanical devices. It is applicable for small (and small diameter) to medium size pipes of diameter range from 25mm to 600mm and provides superior cost performance. Series SX3 Detectors assist in ensuring pumping efficiency and provide accurate leak detection. The adoption of sound velocity measurement system which calculates sound velocity from transit time, keeps the flowmeter unaffected by the temperature and the pressure of the fluid to be measured. Series SX3 sensors come in a variety of small sizes and are available with no acoustic coupling, silicon rubber or silicon-free grease coupling.
