4.6.4 TERMINAL 09-11: FLOWMETER INPUT
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or sine-
wave (coil). The screen of the signal wire must be connected to the common ground terminal 09
(unless earthed at the sensor itself).
The maximum input frequency is approximately 10 kHz (depending on the type of signal). The input
signal type has to be selected in the flowmeter setup (read chapter 3).
Sine-wave signal (Coil):
The F130-P is suitable for use with flowmeters which have a coil output signal.
Two sensitivity levels can be selected:
• COIL-LO: sensitivity from about 80mV
pp
;
• COIL-HI: sensitivity from about 20mV
pp
;
• type ZF, COIL-HI: sensitivity from about 10mV
pp
;
• type ZG, COIL-HI: sensitivity from about 5mV
pp
.
