It uses ultrasonic to measure the vortex frequency and output 4～20mA DC or pulse signal. There is only one vortex producer with no movable part. The vortex frequency measure device is installed on the outside of the pipe so the measure part can not contact with the media. user also can uses flange to contact them.

The measure range of temperature and pressure is very wide. If it matches with indicator or totalizer, it will display instantaneous flow and totalizing value. It also has BRAIN communication function and can use computer terminal to communicate.
