on DPF800 Series

The DPF708/808 Series flow
totalizers can accumulate the mass,
volume or length of an object, and
can provide batch control over the
accumulation. The DPF708 Series
has a single input available in
frequency, voltage or current input
models. The DPF808 Series has an
additional input that is available in
voltage, current or direct
temperature sensor input versions.
Abundant functions such as
retransmission, high/low alarm of
momentary flow and abnormal signal
detecting. The DPF808 Series also
has the ability to trigger alarms for
pressure or temperature. Square
root function is selectable, 8-digits of
accumulation value and 4-digits
momentary process value, small
signal cut-out can be set at any range.

The DPF808 Series has temperature
and pressure compensation used for
general gas, saturated steam,
superheated steam or liquids. The
compensation calculation is done
with standard look-up tables for high
accuracy in steam measurement
applications. Advanced computation
algorithms insure accuracy in flow
measurements. Used as a batch
controller, it has 4-bit accumulator
for control and a separate 12-bit
accumulator for total sum. With high
precision current input models, the
totalizer can provide retransmission
with 14 bit output resolution and

0.2%FS output precision.

Accumulation Time: Fixed at 1 hour
for flow accumulation, and the unit can
be freely set for batch control.

Temperature/Pressure Compensation
Method (DPF808 Series):

General Gas: Temperature-pressure

compensation (calculated with ideal gas
equation)

Saturated Steam: Temperature or
pressure compensation (calculated with
steam tables)

Calculation Accuracy for Temperature
Pressure Compensation:

The calculation error is <0.3% FS, and
after compensation, the overall error
is <0.5% FS

Accumulation Accuracy:

The error is <0.01% FS
Power Supply: 100 to 240 Vac,

-15%, +10%/50 to 60Hz; or 24 Vdc/Vac,

-15% (optional)

Power Consumption: 5 W
Operating Ambient: Temperature

-10 to 60°C; humidity 90% RH
