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.
