DP-F30 Series
The DP-F30 Ratemeter/Totalizer
accepts 3-30 Vdc pulses, dry
contact closure, voltage, or milliamp
inputs, and provides two stage
SPDT relay outputs for batch
control. The display is fully scalable
for engineering units and may be
toggled between batch total, rate,
and grand total. The linearization
option allows the user to select up
to 16 different K-factors over the
input range for accurate indication
of non-linear signals.
Other features include: 12 to 24
Vdc output for powering up
flowmeters; pulsed (.1 to 9.9 sec.)
or maintained outputs; input filtering
for dry contact closure (such as
reed relays); local/remote reset
enable; supplies excitation for open
collector or mechanical contacts;
programmable for auto-reset of
batch total (repeat cycles, 10 Hz
max.); security lockout to prevent
unauthorized changes; factored
pulse output; analog output for
rate or total. (Analog output
not available with square root
-SQRT option.)
The DP-F30 series indicates rate
to 51⁄2 digits and total to 8 digits, with
program and count data stored for
up to 10 years if power is lost.

FC-20 MASS FLOW/BTU
COMPUTER
The FC-20 microprocessor
based Mass Flow/BTU Computer
is used with liquid, gas, or steam
flowmeters to indicate true mass
flow by correcting for changes in
fluid density. Or, model FC-20 can
be used to calculate BTU flowrate
for any fluid. It features direct input
of 100 ohm platinum RTD’s
(E curve), and has an integral
24 Vdc power supply for powering
up pressure and flow transmitters
(4-20 mA, 0-5 Vdc, or 0-10 Vdc
outputs). For flow input, the unit
can also accept 3 to 30 Vdc high
level square wave pulse inputs
(field selectable). For outputs,
the unit has a 4-20 mA output
proportional to mass flow rate
and a TTL level pulse output
proportional to mass flow total.
Both outputs are fully scalable.
The FC-20 also has a multifunction alarm and a separate flow
rate alarm relay.

Computer Interface Capability
Model FC-20
FC-20 displays directly in
engineering units, and stores
program and count data for more
than 10 years if power is lost.
For steam measurement, steam
tables from 14.7 to 3200 PSIA
and from saturation to 850°F of
superheat are used. For saturated
steam, a single temperature or
pressure input can be used. For
gases, the ideal gas law is used.
The FC-20 is fully programmable
through its NEMA 4X-rated front
keypad. A five digit lockout code
can be used to prevent
unauthorized reprogramming.
The FC-20 indicates up to six digits
while total is indicated up to 13
digits, after which the unit displays
in scientific notation.

Add suffix “-220 VAC” for 220 Vac power unit. No charge. Add suffix “-RS232” or “-RS422” for
computer communication option, and add $130 to price of DP-F30 unit, add $96 to price of
FC-20. For DP-F30, add suffix “-SQRT” for square root extraction, add suffix “-MA” for 4-20
mA output, add suffix “-LIN” for 16 point linearization. Add $158 for “-SQRT”, $118 for “-MA”,
$57 for “-LIN”.
Ordering Example: DP-F33-RS232 a ratemeter/totalizer with 4-20 mA input, and RS232
computer communications option, $607 + 130 = $737.
