Frequency output  

Digital output means frequency output and pulse output, and both of them use the same output point, so user 
can choose only one type of them but not both. 

Frequency output range is 0 to 5000Hz, and corresponding the percent of flux 
 
 
 

 

 

 

f  :  Measuring Value 

 

 

 

 

 

Full Scale 

 
The up limit of frequency output can be adjusted. It can be chosen from 0 to 5000Hz, and also can be chosen 
low frequency:  such as 0 to 1000Hz or 0 to 5000Hz. 
 
Frequency output mode can be used in control applica on, because it responses the percent flux. Users can 
choose pulse output when the equipment is applied to count. 
 

Pulse Output 
 

Pulse output mainly applies in count mode. A pulse output delegates a unit flux, such as 1L or 1 M3 etc.  Pulse 
output  unit  divide  into  0.001L,  0.01L,  0.1L,  1L,  0.001  M3,  0.01  M3,  0.1  M3,  1  M3  .When  the  pulse  unit  is 
selected,  please  no ce  the  match  of  the  flux  range  of  flowmeter  and  pulse  unit.  For  volume  flux,  count 
formula as follows:  
 

 

 

 

 

Q (l/sec) 

 : 0,0007854 x ID

2

 x V 

 

 

 

 

Q (m3/sec) 

: 0,0007854 x ID

2

 x V x 10

-3

 

 

Where ; 

ID : Inside diameter (mm) 

V : Velocity ( m/sec) 

 
The oversize flux and too small pulse unit will be made the pulse output over the up limit.  
Generally, pulse output should be controlled below 3000 Pulses/Sec.  
 
Otherwise,  pulse  output  is  different  from  frequency  output.  When  pulse  output  cumulates  a  pulse  unit,  it 
exports  a  pulse.  Therefore,  pulse  output  is  not  equality.  Generally,  measure  pulse  output  should  choose  to 
count instrument, but not frequent instrument. 
 

 
 

Grounding 

Contact area of copper Connector PE on Converter Cabinet for grounding should be larger than 1.6mm2. 

Contact resistance should be less than 10Ω.
