Linearity
•
+/- .7% of full scale over recommended design flow range
•
+/- 1.0% frequency to current conversion
Transducer Power
Digital Output Unit
•
Typically provided by Badger Meter flow monitor or transmitter. Any alternate supply must be of a resistance-
limited type meeting the following constraints:
•
Supply voltage: 9 to 20 VDC
•
Supply current: 2mA maximum
Analog Output Unit
•
10 VDC minimum to 35 VDC maximum. The combination of loop supply voltage and total loop series resistance
must insure that the device voltage remains within these limits over the 4-20mA output span.
Output
Digital Output Unit
• Pulse: square wave (approximately) output @ 1 pulse/revolution
• Voltage:
•
0.4 V maximum (output low)
•
45 V minimum (output high) into high impedance load
Output is 5 volt CMOS and LSTTL compatible. The output can be forced to any logic level up to 20 volts by an external pull-up
resistor.
• Sink
Current: 2mA maximum
Analog Output Unit
• Signal:
Loop powered 4-20mA current analog with offset compensation output for ripple less then 0.25% of full
scale.
