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.
