SITRANS F US SONOKIT offers a simple, accurate alternative to traditional flowmeters because it can be retrofitted onto existing pipelines.  It is a transit time based ultrasonic flowmeter for retrofitting on existing pipelines.

SITRANS F US 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 F US SONOKIT consists of a sensorkit and transmitter. For details and information about the transmitter, see  SITRANS FUS060 and  SITRANS FUS080  (under preparation).    

Application Examples: Water power stations, District heating plants, Water distribution systems, in general all existing  large  water pipelines.

  • Takes complexity out of  retrofitting

  • Cost-effective and accurate solution, containing all the necessary components  

  • Very robust as it can be buried and withstands constant flooding

  • Minimum  maintenance due to the solid construction and no moving parts
