2. GENERAL CHARACTERISTICS
Main task of !"#$%is measurement of instantaneous flow (flow rate), and counting of
total flow (e.g. passage of fluid or gas ), The device can be used as regulator, to control
industrial process.
Measurement of instantaneous flow can be indicated in range: 0 to 999999 (plus decimal
point) and can be expressed in any scalable user units of flow and three time measures
(second, minute, hour). Total flow can be indicated in range from 0.000 to 4294967295 user
units with maximum resolution of 0.001 units. Device can operate with different flow sensors,
acceptable flow factors of sensors from 0.01 to 10000.00 pulses per unit (with resolution 0.01
pulses/unit), additionally these flow sensors can be equipped with either electronic (open
collector) or contact output.
ensors can be powered from sensor supply output (stabilized, 24VDC +5%,
- 10%, 100mA). The device can be equipped with two or four relay (or OC type) outputs, which
can be driven due to instantaneous flow, total flow or batcher counter value. Optionally !"
#$%with two relays outputs (or OC-type outputs) can be equipped with active current output,
passive isolated current output or active voltage output. Build in R 485 interface enables
access to all internal registers, and supports MODBU RTU communication protocol. The

4.3. CONNECTION METHOD
Caution
- Installation should be conducted by qualified personnel . During installation all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC
regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with minimal possible nominal
current value must be used (recommended bipolar, max. 2A) and a power supply
circuit-breaker located near the unit. In the case of using a monopolar fuse it must
be mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in
the case of a short circuit of the cable from the side of the unit the cable shall be
protected against destruction with an electrical installation fuse.

- Wiring must meet appropriate standards and local regulations and laws.
- In order to secure against accidental short circuit the connection cables must be
terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.
- In the case of the unit being fitted with separable clamps they should be inserted
into appropriate connectors in the unit, even if they are not used for any
connections.

- If the unit is equipped with housing, covers and sealing packing, protecting
against water intrusion, pay special attention to their correct tightening or clamping.
In the case of any doubt consider using additional preventive measures (covers,
roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric
shock.
- After the installation is completed do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.

–Avoid common (parallel) leading of signal cables and transmission cables together with
power supply cables and cables controlling induction loads (e.g. contactors). uch cables
should cross at a right angle.
–Contactor coils and induction loads should be equipped with anti-interference protection
systems, e.g. RC-type.
–Use of screened signal cables is recommended. ignal cable screens should be
connected to the earthing only at one of the ends of the screened cable.
–In the case of magnetically induced interference the use of twisted couples of signal
cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used
with R -485 serial transmission connections.
–In the case of measurement or control signals are longer than 30m or go outside of the
building then additional safety circuits are required.
–In the case of interference from the power supply side the use of appropriate anti-
interference filters is recommended. Bear in mind that the connection between the filter
and the unit should be as short as possible and the metal housing of the filter must be
connected to the earthing with largest possible surface. The cables connected to the filter
output must not run in parallel with cables with interference (e.g. circuits controlling relays
or contactors).

4.4. MAINTENANCE
The unit does not have any internal replaceable or adjustable components available to
the user. Pay attention to the ambient temperature in the room where the unit is operating.
Excessively high temperatures cause faster ageing of the internal components and shorten the
fault-free time of unit operation.
In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with
small amount of detergent or in the case of more significant contamination ethyl or isopropyl
alcohol.
Using any other agents can cause permanent damage to the housing.
Product marked with this symbol should not be placed in municipal waste. Please
check local regulations for disposal and electronic products.

6. PRINCIPLE OF OPERATION
After turning the power supply on, device ID and software version are showed on the
display, next the controller goes to the measurement mode.
6.1. MEASUREMENT MODE
In the measure mode, device displays instantaneous measurement (flow value or time
per one unit of flow, depending on „,!” parameter value) equivalent to quantity of input
pulses, total flow or batcher counter value.
Displayed value presentation is defined by parameters D,E, DE and DE
with resolution defined by parameters D,!4E, D!4E and D!4E.
... 879 876 543 . 219
“F unit” “F PrEc”
... 876 543 . 219
“F unit” “F PrEc”
Instantaneous flow (flow rate) is displayed in units defined by parameter D,E and
D,E (min., sec. or h), with resolution defined by D,!4E (max. 5 digits after decimal
point). Pulses delivered to device's input (Figure 4.13) are recalculated according with
procedure showed below:
• if duration of low or high level (between pulses) is lower than time defined by parameter
D,41E(see Tab.7.1 page 33), these pulses are recognized as noise (or bouncing) and will
be ignored
• if duration of both levels are in acceptable range, but input frequency is higher than defined
by parameter D,41E, device goes to alarming state - relays and current output are
switched to their alarm states defined by parameters D0=0 E of particular menus. In
alarm state flow counter displays E"F"E message, in place of flow result.
•In all other cases (while frequency and pulses duty cycle gets acceptable values) input
pulses are delivered to internal prescaler. The prescaler (see description of parameter
D!2= 4=E) should be set to value equal to the quantity of pulses per one unit.
Frequency after prescaler is recalculated accordingly to user defined unit (parameters
D,E and D,E), and after that final flow value in units or thousands of units (e.g.
litres or cubic meters) per hour, minute or second is obtained. This result is displayed on
the display and is used to determine states of relays and current output, additionally the
result is accessible via R 485 interface as a set of holding registers.
–If input frequency is in acceptable range but result is longer than 6 digits, warning
message D"."E is displayed in place of the result. In that case parameters
D,E, D,EandD,!4Eshould be corrected to obtain proper result.
–While time per one unit of flow is displayed (parameter D,!E = “!4”):
• If flow value equals 0, then 0 value is displayed.
• If value of period is to high to be fitted on 6 digits, message D".="E
(Overload) is displayed instead of the result.
•If flow value is different than 0 but value of period is to small to be fitted on
6 digits, message D"2="E(Underload) is displayed instead of the result.

User manual - FLOW METER SPI-638
Total flow is displayed in units defined by parameter DE with resolution defined by
parameter D!4E (max 3 digits after decimal point). If total flow counter overflows, warning
DE is displayed alternatively with maximum counter value. Total flow counter can be
zeroed using D/E option of D0=E submenu, using @S A button (press and hold by at
least 2 sec.), electrically via total flow cl aring input or via R -485 interface by writing of value
0000h to any of total flow counter result registers.
Zeroing by @SA button can be activated using „/=” option of D0=E submenu.
Zeroing via total flow cl aring input can be activated using „4/=” option of D0=E
submenu (see page 38).
Batching counter value is displayed in units defined by parameter DEwith resolution
defined by parameter D!4E (max 3 digits after decimal point). If batcher counter overflows,
warning D0E is displayed alternatively with maximum counter value. Batching counter can
be zeroed using D/=0Eoption of D0/FE submenu, using @SA button (press and hold by
at least 2 sec.), electrically via batch r cl aring input or via R -485 interface by writing of value
0000h to any of batcher counter result registers.
Zeroing by @SA button can be activated using „/=” option of D0/FE submenu.
Zeroing via batch r cl aring input can be activated using „4/=” option of D0/FE
submenu (see page 36).

while total flow is displayed. If batcher counter is displayed then DSE LED is pulsing.
Batching counter can be displayed while batcher mode only (set „ /4”=”0” in
G4=0'Esubmenu).
Functions of @BAand@Abuttons depend on kind of presently displayed value:
• If instantaneous flow (flow rate) is displayed (LED marked DSE is off) or batcher counter
value (DSE LED is pulsing), user can check main threshold values and numb r of batch s
count r (which indicates how many times batcher was started). After pressing @BA or @A
buttons, name of the threshold (e.g. E4=!'E) and its value or E0/E label and
numb r of batch s count r will be displayed on the display in alternating mode.
If @BA or @Awill be pressed in 5 sec again, the next threshold will be displayed, else the
device comes back to the measurement mode. If a free access is enabled (see description
of ”SECu” menu), user can change the value of particular threshold pressing button
@484(A (see: PARAMETERS EDITION). Using @S A button while numb r of batch s
count r is displayed and confirm G/=40HE message by @484(A button causes zeroing
numb r of batch s count r.
• If particular parameter has been changed and confirmed in quick view mode, its
new value is displayed in alternating mode with parameter name by few seconds.
Confirmed changes may be checked or user can switch viewed parameter
pressing @BAor @A button.
•Numb r of batch s counter is incremented after each start of batching process
(every first start after batcher counter zeroing).

exceeds 6 digits, then decimal point of the most left digit is pulsing. To view most
significant digits, it is required to decrease resolution or/and change unit.
• If total flow counter value is displayed ( LED marked DSE is on), and its length exceeds 6
digits, buttons @BA and @A enable switching between more and less significant digits.
Positions of currently displayed digits are signalized by flashing decimal points (see
example below).
Example of switching between less and more significant digits of total flow result .

Let, total counter result be equal 1236789876543.21:
–while less significant 6 digits are displayed, flashing most left decimal point signalizes
that result is longer than 6 digits, to show more significant digits press @BA,
–while medium digits are displayed both most left and most right decimal points are
flashing (Figure 6.1). Most right decimal point signalizes than result has less significant
digits – to see these digits press @A button. Most left decimal point signalizes
additional more significant digits. Press @BA button to see these digits.
–while most significant digits are displayed, most right decimal point is flashing, and
signalising that result has less significant digits, to see these digits press [v].
All accessible parameters (e.g. pulse input settings, decimal point position) can be
changed by entering the menu (see: DEVICE PROGRAMMING). Use the local keyboard or
the remote controller to do it. (Note: all parameters can be remote changed via R -485
interface).
Counting of pulses and controlling or relays is realised regardless of operation mode
(after entering to menu mode counting and controlling is continued in “background”.
