User ManualFST030 is based on the latest developments within Digital Signal Processing (DSP) technology – engineered for high measuring performance, fast response to step changes in flow, high immunity against process noise, easy to install commission and maintain.
The FST030 transmitter delivers true multi-parameter measurements i.e. volume flow, standard volume flow, density, mass flow, fluid sound velocity and temperature.
The multiple outputs and bus communication mean that all primary process information can be read either instantaneously (10 ms update) or periodically as required by plant operations.

Up to six I/O channels are configured as follows.
Channel 1
Channel 1 is 4 to 20 mA analog output with HART 7.5. The current signal can be configured for massflow, volumeflow and includes the availability of active or passive function selected by wiring on the non-Ex terminals. Alternative Modbus RTU RS 485 is available.
Channel 2
Channel 2 is a signal output which can be freely configured for any process variable.
- Analog current (0/4 to 20 mA)
- Frequency or pulse
- Operational and alarm status
Channels 3 and 4
Channels 3 and 4 can be ordered with signal (freely configured for any process variable) or relay outputs, or signal input.
Signal output
Signal output can be user configured to:
- Analog current (0/4 to 20 mA)
- Frequency or pulse
- Redundant frequency or pulse (linked to channel 2)
- Operational and alarm status
Signal input
Signal input can be user-configured for:
- Totalizer reset functions
- Force outputs or freeze process values
- Initiate automatic zero point adjustment
Relay
Relay output(s) can be user configured to:
- Alarm status
4-20 mA signal outputs and inputs are ordered as active or passive for Ex versions, active and passive for non-Ex versions – function selected by wiring on the terminals.
During initial commissioning of the flowmeter, all outputs can be forced to a preset value for simulation, verification or calibration purposes.
Channels 5 and 6 (with internal DSL)
- RTD temperature inputs for 1000, 500 or 100 Ω RTD’s – 2, 3 or 4 wire RTD’s supported
- Channels 5 and 6 (with external DSL option)
- RTD Temperature inputs or 4-20 ma inputs. Selectable in menu.
Approvals and certificates
The SITRANS FST030 transmitter was designed to comply with or exceed the requirements of international standards and regulations.
Design
The SITRANS FST030 is designed in an IP67/NEMA 4X aluminum enclosure with corrosion resistant coating. It can be wall or pipe mounted and the enclosure can be locked with a padlock or wired with lead security seals. Includes all flow and DSL functions integrated into one unit.
The FST030 is available as standard with one current, HART 7.5 output and can be ordered with additional input/output functions.
The transmitter has a modular design with discrete, replaceable electronic modules and connection boards to maintain separation between functions and facilitate field service. All modules are fully traceable and their provenance is included in the transmitter setup.
SensorFlash
SensorFlash is a standard, 4 GB micro SD card with the ability to be updated by PC. It is supplied with each transmitter and comes with a complete set of certification documents including report if ordered. Factory conformance certificates are optional at ordering.
The Siemens SensorFlash memory unit offers the following features and benefits:
- Copy site setups to SD card for easy transfer to other similar transmitters
- Permanent database of operational and functional information from the moment that the flowmeter is switched on
- New firmware updates can be downloaded from the Siemens internet portal for Product Support and placed onto Sensor-Flash (unmounted from the transmitter and inserted into a PC’s SD card slot). The firmware is then inserted into the existing flowmeter for system/firmware upgrade.
