The maximum vertical diaphragm seal spacing shown in the table applies to level measurement,
ensuring that it is possible to set the zero point of the transmitter when the tank is empty.
For measurements of density or phase boundaries (in the sugar and chemical industries and in
refineries) the vertical spacing of the diaphragm seals can be larger.
5.3.3. DPR-2000ALW, DPR-2200ALW Metrological parameters
Accuracy ± 0,075% (FSO) for the DPR-2000ALW nominal range
Long term stability

accuracy / 3 years
Error due to supply voltage changes ± 0,002%(FSO)/1V
Thermal error ± 0,08%(FSO)/10ºC
Thermal error for the whole thermal
compensation range
± 0,3%(FSO)
Zero shift error for static pressure* ± 0,08 % (FSO)/10bar
± 0,01 % (FSO)/10bar (for range n°4)
± 0,03 % (FSO)/10bar (for range n°5, 6)
Cut-off on radical characteristic curve up to10% of flow.
* zeroing in static pressure conditions with zero differential pressure eliminate this error.
