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.

SPECIFICATIONS
Frequency Input: 0 to 3200 Hz
Temperature (DPF808 series): J, K or E thermocouple, 1 to 5, 0 to 5 Vdc or 4 to 20 mA
Pressure (DPF808 Series): 1 to 5, 0 to 5 Vdc or 4 to 20 mA
Accumulation Time: Fixed at 1 hour for flow accumulation, and the unit can be freely set for batch control.
Frequency Input Models: 0 to 3200Hz, the low level signal is 0 to 1V, the high level signal is 3 to 24V
Voltage Input Models: 1 to 5 V, 0 to 5 V, providing 24 Vdc/24 mA power output
Current Input Models: 4 to 20 mA, 0 to 20 mA, 0 to 10 mA
Temperature Input (DPF808 Series): K (0 to 999C), E (0 to 800C), J (0 to 999C) RTD Pt100 (-200 to 600C)
