D08-8C Flow Accumulator
Operating Instruction
1. APPLICATION
D08-8C Flow Accumulator provides operating power supply, flow accumulating, instantaneous flow
rate and cumulate flow rate digital display of MFC/MFM. General speaking, D08-8C Flow
Accumulator is compatible with D07 series MFC & MFM, and it can also compatible with other MFCs.

3. OPERATION PRINCIPLE
D08-8C Accumulator is consisted of ±15V power supply, 5V power supply, modulus converter,
instantaneous flow & cumulated flow displayer, 6 keys and communication part. The flow test
voltage (0V~+5V) that came from MFC/MFM converts to digital signal after pass through A/D
converter to operate and cumulate processing in SCU( Single Chip Micyoco ). After that, the
instantaneous flow rate is delivered to four-place-LED displayer, the displaying units are SCCM
(Standard Milliliter/Min) or SLM (Standard Liter/Min); it also could be: SLM or KSLM (Standard
Kiloliter /Min, viz. Standard M3/Min). The cumulated value is delivered simultaneously to
6-place-LED displayer, the displaying units are SCC (Standard Milliliter) or SL (Standard Liter);
it also could be: SL or KSL (Standard Kiloliter, viz. M3).
The maximum cumulated flow could match to 999999 SL, if MFM unit is SCCM, the preliminary
cumulated flow unit is SCC, when cumulated value matched to 1000 SCC, the cumulated flow
unit will change to SL automatically. If cumulated value exceeds the maximum, the
arithmometer will reset automatically and begin accumulating from zero. If user used 100
SCCM MFM, the minimum cumulated time could match to 166666.67 hours(about 19 years).
Our Flow Accumulator is quite good at long-time continuous accumulation, circulate
accumulation, cumulated value radix point and unit automatic adjustment.
D08-8C Accumulator offers Serial Communication function, it can communicate with master(PC)
via Standard RS232 or RS485 Serial Communication Interface ( RS-232 and RS-485 is
switched by the slide switch S2 on circuit board). Please refer to the Chapter 4.5 for more
details of the serial communication. Please refer to appendix one for more details of the
communication protocol.
4. INSTALLATION & CONNECTION
4.1 Dimensions: It used standard plastic chassis, as showing in figure 1:

4.2 Installation Tapping Dimensions: ( 67×67 )mm
4.3 Installation Mode: Standard Inlay Installation
4.4 Front panel view(Figure 2) and rear panel view(Figure 3)

4.5 Seriel communication connection(Figure 4)
Page 4of 34
Figure4. 9-pin Standard D-Sub socket
When you use one Master(PC) communicated with one D08-8C Accumulator, we commend RS232
communication mode; When you use one Master(PC) communicated with many D08-8C
Accumulators( the maximum is 16 ), we commend RS485 communication mode;
When you select RS232 communication mode:
Please connect pin 2(TXD) , pin 3(RXD) and pin 5(SG) showed in figure 4 to PC’s standard
RS232 serial port’s corresponding pin 2(RXD),pin 3(TXD) and pin 5(Signal COM);
When you select RS485 communication mode:
Please connect pin 6(A ＋) , pin 7(B －) showed in figure 4 to the Master(PC)’s standard
RS485 serial port’s corresponding pin(A ＋), pin(B －). In fact, this is the Half-Duplex RS485
Communication Mode, you should set every 8C Accumulator to the different address, the
Master(PC) can discern every 8C Accumulator by the different address, in this mode you can use
one Master(PC) communicate with 16 8C Accumulators (if you want know more about the
communication protocol, please read the Appendix One).
4.6 15 pin Standard D-Sub connection with MFC
Page 5of 34
Figure 5. 15 pin Standard D-Sub connection with MFC
It can be directly connected with MFC through D-Sub by cable.
4.7 ~220V power connection is showed in figure 3. For the sake of safety GND must be connected.
5. OPERATION
5.1 Startup
There is no power switch of Flow Accumulator, it could be operated after external alternating
current connecting.
5.2 Initial State
“ Valve Drive ” is default when you connect external alternating current, the green “ Valve Drive ”
LBD will light at the same time. Full scale readout defaults to 100.0SCCM; communication address
Page 6of 34
defaults to 1, and cumulate flow unit defaults to SCC.
5.3 Keys Definitions
The D08-8C Accumulator is operated and configured by the six keys in the front panel, The keys’
meaning is shown below:
“SET “Key
This key is used to implementation functions under mentioned in 5.4, it has six submenus.
“OK” Key
This key let users enter the menu and save the value they have set.
“＋” Key
This key can increase the value of Full Scale, Flow Setpoint and Address, when you quickly press
this Key one time, the value will goes up “1”, when you press this key and continue several seconds,
the value will goes up continuously.
“－” Key
This key can diminish the value of Full Scale, Flow Setpoint and Address, when you quickly press
this Key one time, the value will goes down “1”, when you press this key and continue several
seconds, the value will goes down continuously.
“AUTO” Key
MFC’s valve defaults to “ Valve Drive ” when the power is connected. This key can make MFC’s
valve reset to “ Valve Drive ” state when MFC’s valve is in “OFF” or “PURGE” state.
“OFF” Key
This key is used to set MFC’s valve state to “OFF” state.
