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.

Cut-off on radical characteristic curve up to10% of flow.
*) zeroing in static pressure conditions with zero differential pressure eliminate this error.
APR... transmitters, in the PED Pressure Directive versions, are produced with a measurement range in the
interval from –100 kPa to 2,5MPa, with the static pressure 25MPa and the overpressure up to 27,5 MPa.
The permissible operating temperature for option according to H1D+H1 Module is between -25°C and 100°C.
The permissible operating temperature for option according to B+D Module is between -25ºC and 70ºC.
APR transmitters... which conform to PED are characterised by a measurement range of between -100kPa and
2.5MPa, static pressure of 25MPa and the overpressure of 27.5MPa.
