* No moving parts to foul or wear
* No pressure drop or energy loss
* Wide turn-down ratio
* Single or dual path with internal DSL, up to four paths with external DSL option

SITRANS FS230 standard functions are suitable for a wide variety of liquid applications, including the following:
* Water industry

* Raw water
* Potable water
* Chemicals
* Wastewater industry * Raw sewage
* Effluent
* Sludges
* Mixed liquor
* Chemicals
* HVAC industry * Condensers
* Hot & cold water systems
* Power industry * Nuclear
* Fossil
* Hydroelectric
* Processing industry * Process control
* Batching
* Rate indication
* Volumetric and mass measurement
SITRANS FS230 hydrocarbon functions are ideal for applications carrying crude oil, refined petroleum or liquefied gas.

The electronics for creating measured values for an ultrasonic measurement are located in a compact module called: Digital SensorLink.
Together with the ultrasonic sensors, this module creates an analogue measurement signal for volume flow and lots of other data.All data is then immediately digitized and sent to the transmitter without interference.
The advantage: best possible EMC thanks to very short analog signal lines and safer data transfer to possible transmitter variants.
The FS-DSL is suitable for clamp-on sensors as well as for inline - SONO sensors, the set firmware determines the respectivetechnology. The FS-DSL is available for water applications, for oil measurements and also for clamp-on gas measurements.
The module can be used in Ex-Zone 1 (Class 1 Div 1) as an external FS-DSL in a pressure-encapsulated IP 66/67 housing. Thedistance to the transmitter can be up to 150 m, which is also how the FS-DSL is powered. The FS-DSL offers analog inputs for temperature and pressure and is always designed for up to 4 measuring paths in the external version.
Option:
Optionally, the FS-DSL module is also available integrated in the SITRANS FST030 only in the version as a wall housing, but then with reduced EMC, number of paths and Ex version.
