2. In a typical measurement situation the following peaks appear in the echo curve Reference peak This reference pulse is caused by the transition between the transmitter head and the probe antenna For the Rosemount 3300 and 5300 Series the pulse is negative while for the Rosemount 5400 and 5600 Series the pulse is positive see Figure 5 6 on page 68 For Rosemount 5301 with DVC the seal pulse is used as reference See Table 5 2 on page 67 for the typical reference pulse amplitudes for the Rosemount 5300 Series Reference reflector peak Rosemount 5300 with DVC only This reference reflector pulse is caused by the transition between reference reflector and continuing part of the probe The pulse is negative but not as strong as the reference pulse In RRM it should be labelled as P2 other or P3 other if surface echo centering disk is present after vapor compensation is calibrated see Commissioning on page 35 The amplitude of the reference reflector peak is dependent on the installation chamber diameter and the process conditions of the application See also Figure 4 5 on page 55 Surface peak This pulse is caused by a reflection of the product surface See Table 5 1 for typical surface peak amplitudes for the Rosemount 5300 Series Note that the amplitude is dependent on the dielectric constant of the media transmitter type probe antenna type process conditions vapor turbulence foam etc distance to echo etc Probe
