Sampling interval
1) For factory setting, see chapter 10.1 Factory Setting of Outputs for DN15 / DN20 / DN25 and
chapter 10.2 Factory settings of the outputs DN32 / DN40 / DN50.
2) The tolerance specifications include the uncertainty of the factory calibration with a coverage factor k=2 (2 x standard deviation).
The tolerance was calculated in accordance with EA-4/02 following the GUM (Guide to the Expression of Uncertainty in Measurement).
3) T he flow meter is factory adjusted at 7 bar (abs, 102 psi). Pressure compensation is valid for v = 10...120 m/s. Without entering the system
pressure into the EE741, the pressure dependency is ±0.5 % of the measured value / bar deviating from 7 bar.
