Pulse comparison 

Pulse generator errors can be detected early using pulse comparison. 
In principle, any two pulses may be compared. The process for securing the custody transfer measurement 
using a pulse generator on input 2 to monitor the pulse generator on input 1, is described here. 

 

i 

The pulse generator used for pulse comparison must have the same pulse value (cp value)! 

 

With regard to the "HF pulse input with automatic conversion" described in chapter 4.4 the calibration lock 
must not be open and the input 2 terminal must not be sealed, as they are not used in custody transfer 
measurement. This means also that, should the pulse generator on input 1 fail, the volume will not be 
incremented further, but instead a warning will be given. 

 

If the "maximum number of disturbance pulses" set in the "pulse window per disturbance pulses"  

 

the message "

I2 Pulse cmp

" momentary status "

Stat

" and status register "

SReg

" is entered, 

 

"W" flashes in the display. 

An impulse window is also calculated, to allow a certain number of error pulses, below which the message is 
removed from the momentary status. Until the status register is cleared by the user the message and the "W" 
in the display will remain permanently (unless another warning is generated). 

 

The status message can then be used, for example to create an archive entry or to switch an output. 

 

4.5.1 

Pulse generator connection 

 

 

Danger! 

For EK280 with internal power supply, the mains voltage must be switched off before 
opening the housing, ensure it is not turned back on and verify that there is no voltage.

Connect the low frequency pulse generator (LF reed contact) of the gas meter used for the custody 
transfer measurement to terminal "DE1" of the EK280. 

 

Connect the second low frequency pulse generator (LF reed contact) to terminal "DE2". 

 

4.5.2 

Parameterization 

To program input 2 for the pulse comparison with input 1, send the following parameter file to the EK280 
using the parameterization program "enSuite" (see chapter 3.6 "Send parameter file", page 17): 

 

EK280 - Input 2 = Pulse Comparison with input 1 (*)
