Mounting Position

Effects

Models	Mounting Position Effects
2051C	Zero shifts up to ±1.25 inH2O (3,1 mbar), which can be calibrated out. No span effect.
2051T	Zero shifts up to ±2.5 inH2O (6,2 mbar), which can be calibrated out. No span effect.
2051L	With liquid level diaphragm in vertical plane, zero shift of up to 1 inH2O (2,49 mbar). With diaphragm in
	horizontal plane, zero shift of up to 5 inH2O (12,43 mbar) plus extension length on extended units. Zero
	shifts can be calibrated out. No span effect.
