Reference Manual 00809-0200-4480 Transmitter overview May 2021 2 Transmitter overview 2.1 Measurement principle The Rosemount 1408A is a transmitter for continuous level measurements using fastsweep Frequency Modulated Continuous Wave (FMCW) technology. The transmitter continuously emits signal sweeps with a constantly varying frequency towards the product surface.
Transmitter overview May 2021 2.2.2 Reference Manual 00809-0200-4480 Foam and turbulence Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. Surface turbulence is not normally a problem unless it is excessive. Measurement in foamy applications depends largely on the foam properties. When the foam is light and airy, the actual product level is measured. For heavy and dense foam, the transmitter may measure the level of the foam’s upper surface. 2.

Option Length unit Temperature unit Volume flow unit Metric m °C m3/h Imperial inch °F US gal/h After appropriate units have been selected, all configuration parameters and transmitter variables will be expressed in these units. C.2.2 Reference height Distance between the Device Reference Point and Zero Level.

Configuration parameters May 2021 Reference Manual 00809-0200-4480 Options for alarm on delay Table C-1: Alarm On Delay Option Description Always Alarm on delay is always used. Lost surface Alarm on delay is used only for lost surface alarms. This may be useful in applications when there are small and local rapid level changes caused by surface turbulence. Hardware faults and measurement values that exceed the alarm set points will trigger alarm without any delay.
Reference Manual 00809-0200-4480 Configuration parameters May 2021 Low alarm Enable or disable the low alarm. Alarm set points SP1 - High alarm set point If the measured value is above this set point, the digital output is set to alarm state. SP2 - Low alarm set point If the measured value is below this set point, the digital output is set to alarm state. Hysteresis The hysteresis is a buffer zone so the alerts do not toggle on and off when the measurement value fluctuates around the alarm limit.

Configuration parameters May 2021 Reference Manual 00809-0200-4480 Bottom offset The Bottom Offset is defined as the distance between Zero Level and the tank bottom. The default value is zero. If the Zero Level is not located at the tank bottom, then enter a Bottom Offset. It is needed for the transmitter to know the position of the tank bottom. Figure C-7: Bottom Offset A B C D + A. B. C.
