：
Because the max. frequency the magnetic counter can respond is 5Hz, it is necessary
that a requirement

ITEM
DESCRIPTION
Input
Pulse Generator Delta meter preamplifier PA15 or 25
Signal Levels
"1": 20mA min.; "0": 4mA max.
Overcurrent Detection PA15 and 25: An erratic probe is indicated above 27
±
4mA (LED flickers).
Pressure
Front-panel digital switch establishes the operating pressure
(0.00 to 1.99MPa in 0.01MPa steps).
Meter Size (nominal
bore)
Internal rotary switch establishes value which agrees with meter size.
For rotary switch positions, see Section 8.(2) "Setting of Meter Size (nominal bore)."
Meter Error
Internal jumper establishes corrections (in a range of from 0.0 to
±
7.5% in 0.5% steps).
Scaling (totalizer)
Internal jumper establishes the factor of frequency reduction (1/10 or 1/100).
Scaling (Output)
Internal jumper establishes the factor of frequency division (1/1 or 1/10 or 1/100).
Pulse Output after Conversion
in Terms of Mass
Open collector max. rating: 30V DC, 0.1A
Pulse width: 1-4ms., 40-60ms. (with 1/10 or 1/100 reduction)
Analog Output after
Conversion in Terms of Mass An analog output of instantaneous flowrate in terms of mass (option)
Accumulated Total Display 7-digit electromagnetic counter
