								The verifying of the calibration factors on-site 
 								is possible with mobile standards...
  
								  ... the mobile standards are 
								      the sensors of the type dQ-m and dQ-h
  
								  ... the current measurable flow rates 
								      are 0.002 ... 180 L/h
  
								  ... the combined uncertainty of the 
								      mobile standards is better than 0.1%
