SITRANS FUS SONOKIT offers a simple, accurate alternative to traditional flowmeters as it can be retrofitted onto existing pipelines. Being a transit time based ultrasonic flowmeter,SITRANS FUS SONOKIT has in-line transducers which assure superior accuracy and performance. The kit includes all necessary parts and special tools to make the installation as 1- or 2-track flowmeter. It is made for installation on empty pipes or pipes under pressure without process shut-down (hot-tap). 

The SITRANS FUS SONOKIT consists of a sensorkit and transmitter. For details and information about the transmitter, see  SITRANS FUS060 and  SITRANS FUS080.
