Being that the SITRANS FST020 clamp-on ultrasonic flow meter offers basic functionalities, it is considered an optimal and affordable alternative to more complex flow measurement solutions.
To make product selection straightforward while still offering solutions that fit the requirements of the water and wastewater, HVAC, power, chemical and general process industry, the product configuration has been simplified.
In turn, the SITRANS FST020 features a user-friendly design, a very competitive price and delivery times that are up to par with market expectations.
Application examples include processed sewage, sludge, chemical feed, process control, coolant flow and fuel flow.
Pair the SITRANS FST020 with the SITRANS F US Thickness Gauge to ensure precise flow measurement.
