Description
SITRANS FS120 7ME3570 Ultrasonic Flowmeter
The SITRANS FSS100 is the perfect choice for highly accurate flow measurement on existing or new pipes. The SITRANS FSS100 inline ultrasonic sensor package includes necessary tools for the installation of 1 to 4 path measurements. Positioning of the transducers directly in the medium enables long-term stable and accurate measurements
Overview---SITRANS FS120
SITRANS FS120
The SITRANS FST020 is the basic device for simple and cost-effective solution for FSS100 inline and FSS200 clamp-on sensors. To combine the SITRANS FST020 with the FSS100 sensors, please order the transmitter SITRANS FST020 and the sensors SITRANS FSS100 separately. With the SITRANS FST020 only a single-path measuring is possible.
As a single-path device, it is suitable for flow measurement on liquids that do not require temperature or viscosity consideration and where highest accuracies are not required.
The SITRANS FST020 is part of a digital platform 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 and simplicity in installation, commissioning and maintenance.
The FST020 transmitter delivers standard parameter measurements i.e. volume flow, flow speed or sound velocity by analog outputs and Modbus communication.
Process values
- Volume flow
- Flow velocity
- Sound velocity
- Totalizer 1
Benefits
Flow calculation and measurement
- Dedicated volume flow calculation with DSP technology
- 100 Hz update rate for all primary process values
- Maximum data age from sensor to output is 20 ms
- Independent low flow cut-off settings for volume flow and velocity
- Zero-point adjustment on command from discrete input or host system
Operation and display
User configurable operation display:
- Fully graphical display 240 × 160 pixel display with up to 6 programmable views
- Self-explaining alarm handling/log in clear text
- Help text for all parameters appears automatically in the configuration menu
SensorFlash technology stores production specific system documentation and provides removable memory of all flowmeter setups and functions:
- Calibration certificates (with ordered calibration)
- Non-volatile memory backup of operational data
- Transfer of user configuration to other flowmeters
- 8 GB SD card org higher for storage and data logging
- Audit trail of all parameter changes
- Alarm logging
Alarms and safety
- Advanced diagnosis and service menu enhances troubleshooting and meter validation
- Configurable upper and lower alarm and warning limits for all process values
Outputs and control
Monitoring comprised of 1 individually configurable totalizer.
Single parameter outputs that can be assigned individually to any of the following parameters:
- Volume flow
- Flow velocity
- Sound velocity
- Flow direction
Channel 1 is 4 to 20 mA analog output. The current signal can be configured for passive volume flow.
Relay output(s) can be user configured to Alarm status or warning. Modbus RTU RS 485 comes as standard.
Signal input
The signal input can be user configured for:
- Totalizer reset functions
- Forcing outputs or freezing process values
- Initiating automatic zero point adjustment
