Frequency, Flow Rate Propor onal (Rate)
Digital Output
Power Required
The CentriFlow® Meter Electronics is capable of outpu ng a Totalizing Pulse Output signal.
The Frequency, Flow Rate Propor onal signal is a pulse signal and is labeled “Rate” at the
CUSTOMER CONNECTION block. The frequency of the signal is 0 to 500 pulses per second.
The Rate +, supplied by the customer can be between 12 and 24 Volts. The Rate
‐
is connected
to the Common or Power Supply Ground. By connec ng the Rate + and Rate
‐
with customer
supplied power and ground, the Rate Out signal will be isolated from the Digital Electronics.
Although the preferred method of supplying power to the Rate output is customer supplied
power, +24V local power is also available. Using the local power, however, results in a loss of
isola on.
This Totalizing Pulse Output will output a Voltage Pulse that is related to the Electronic Full
Scale Flow Rate. For example, if the Electronic Full Scale Flow Rate were calibrated to be 300
lb./min, then a
fl
ow rate of 150 lb./min would correspond to a pulse of 250, or 50% of Elec
‐
tronic Full Scale Flow Rate.

Pushbu on Switch
By installing a push bu on on/o
ff
switch or other mechanical relay contact, the Remote Input
can be used to remotely reset your count. In order for this op on to be u lized the push
bu on on/o
ff
switch or other mechanical relay contacts (customer supplied) must be installed
using the connec on listed below. Please note that these inputs are prewired with voltage
and only require contact closures to operate correctly (Wiring an SSR to this input will not
work properly).
