Product Details

The SITRANS FS290 is a portable ultrasonic flowmeter system for monitoring volumetric flow in pipes. It contains the SITRANS FST090 battery-operated transmitter and SITRANS FSS220 clamp-on sensors. Install the sensors quickly and easily on the outside of a pipe, without any process interruptions or plant downtime.

How does it work?

Each measuring path is formed by two coordinated sensors that transmit ultrasonic signals back and forth through the pipe. Using the time difference between the two signals, the transmitter calculates the resulting measurement.

The transmitter performs analog signal processing for the sensor pair and digitalizes the generated measurements for display. The data measured is periodically recorded on the inserted SD storage card. Data output can be user-defined or take place via either analog signal or Modbus RTU.

Users can install clamp-on sensors on the pipe during ongoing operation, which means the pipe is not cut open and the flow does not need to be stopped.
