The DPF400 Series is a complete
line of flowrate indicators offering
exceptional performance at an
economical price. Individual models
are available for flowrate and
totalization (with or without square
root extraction) batch control.
The DPF400 is front panel
programmable to scale any input
range to display in desired
engineering units. Independent
scale factors for rate and total allow
rate indication and totalization in
different units, such as GPM rate
and total barrels. If the optional
RS-232 or RS-485 communications
are installed, the unit may also be
programmed by remote computer.
The DPF400 is available with
4 input types, including TTL/open
collector pulse, low level frequency,
analog voltage or analog current.
The unit can be user-configured
for one of three functions:
- a ratemeter/totalizer/batcher
- a ratemeter/totalizer/batcher
with square root extraction
(for differential pressure
flow measurement)
- a batch controller only with
multibatch counting, auto/manual
batch recycle, and remote or
local STOP/CONTINUE control
(START control can be obtained
with a user supplied switch in
series with the control relay)
Options to the DPF400 include
analog and BCD outputs,
alarm/control outputs, and RS-232
or RS-485 communications.
The RS-232 or RS-485
communications options are
bi-directional, allowing the user
to configure the DPF400 as well
as read current values.
While each DPF400 comes
standard with 5 open collector
outputs, the optional DP40-R board
provides dual 7A mechanical relays
which replace two of the open
collector alarms, for a total of
two 7A relay and three open
collector alarms.
