1-yearfrom the delivery date we will repair the unit at our factory or provide you
with a replacement unit or sub-assembly at our discretion. A return authorization
number must be obtained from FineTek before returning any unit.
➢If the EPR1 product failed to operate out-of-the-box, and this failure was not due to
transportation, handling or incorrect Installation, then you can request a
replacement unit within 7 days from the delivery date.
➢When returning a product to the factory, return the entire device and do not
disassemble the unit as previously mentioned. In addition, wherever possible
please returning the device please ensure it is packed to avoid damage during
transportation.
➢The EPR1 product is designed for general use. Special applications, extraordinary use
and overloading or operating beyond published specifications may void the warranty.
➢The product is not warranted in the following situations or conditions, therefore
charges will result for repair of product:
⚫The product is beyond its warranty term.
⚫The defect or damage to the product is caused by the incorrect operation or
by not following the installation and operation instructions contained within the
operation manual.
⚫The product damage is a result of force majeure factors, including but not
limited to natural disasters, floods, fires, earthquakes, lightning, severe
weather conditions such as hurricanes, typhoons, tornadoes etc., human
error such as use of improper voltage, high-humidity, water leakage, stains,
corrosion, loss, improper storage etc. and other abnormal factors.
⚫The damage is caused by installation, addition, expansion, modification and
repair of parts not authorized specifically or certified by FineTek.
⚫If the data label information on the product is incorrect or unclear so as to not
be able to read or confirm the product serial number.
2.2 Repair warranty
Repaired product is warranted for 6 months from the delivery date. The warranty is
limited to the part(s) replaced or repaired during the repair. If the repaired or replaced
part is defective within this term the same part(s) will be repaired or replaced free of
charge.

B.M12,8Pinelectrical cable(Withdisplay)
C. Operationmanual
3.3 Productintroduction
The principle of operation of the paddlewheelflowmeter uses the paddlewheel blades rotation to
measure the flow velocity, based on which the flowrate is calculated. The ERP5 paddlewheel
flowmeter consists of the flow sensor/transmitter and the T fitting pipe. With its compact design,
the unit is veryeasy to install. The sensor "K value" is determined during upon factory calibration
with an accuracy of 3%. The paddlewheel flowmeter will provide good linearity within the units
rated velocity range of 0.3~10 m/s (1.0~32 ft/s) at Plastic Blade or 0.5~8 m/s (1.6~26 ft/s) at
Stainless Blade. The EPR1 paddlewheel flowmeter is available with or without a local display.
The EPR1 with local display has built in memory to store the accumulated or totalized flow data
so anoperatororusermayconvenientlyreadthisdata.
3.4 Productapplications
The Paddle Wheel Flow Meter is applicable to neutral or corrosive liquids that are non-
granular or non-viscous. It connects with an analog output and pulse output signal to form
a monitoring system, which can display instantaneous flow and accumulated flow.
Moreover,itcanformacontrolcircuittoadjustthevalveoroperatetheswitch.
The ERP5 can be used in a variety of industries; food and beverage, water treatment,
pharmaceutical,dyeing,chemicals,semi-conductorandPCBwetprocesscontrol.
※The detected medium must not contain any iron filings, particles which will attached the
rotary paddle wheel and affect the accuracy and also cause damage. If there is possibility
to have iron filings, particles in the process or pump operation, please install the magnet
scree n filters (please consider the Pressure loss) on upstream side for the minimum
distance15timesofpipediameter.

4.5 Assembly Instructions
With Display
1. Flow meter T-fitting.
2. Install the O-ring into the sealing groove and let it
expand naturally.
3. Pass the film seat, facing downward, through the
hole and the O-ring.
4. Install the screw X4; fasten them evenly and flatly.
*Locking torque:
Plastic blade = 8~10kgf-cm (0.784~0.98N.m)
SUS blade = 10~12kgf-cm (0.98~1.176N.m)
5. Point the M12 joint of the display towards yourself
and insert into the recess at the precise angle. Attach
flatly and turn clockwise till the edges are aligned.
6. Fasten 1 positioning screw and tighten it.
* Locking torque = 6~8kgf-cm (0.588~0.784N.m)
*Note: Perform Steps 1~6 for installation of the entire
machine. If only the meter head is installed, please
perform Steps 5 and 6.
Please install the screw locking torque in accordance with
the prescribed range.
Without Display
1. Flowmeter T-tube.
2. Install the O-ring into the sealing groove and let it
expand naturally.
3. Pass the transmitter blade, facing downwards,
through the hole and the O-ring and attach it flatly and
in alignment.
4. Install 4x screws; fasten them evenly and flatly.
*Locking torque:
Plastic blade = 8~10kgf-cm (0.784~0.98N.m)
SUS blade = 10~12kgf-cm (0.98~1.176N.m)
*Note: Please install the screw locking torque in
accordance with the prescribed range.

4.6 Troubleshooting
Error
Inspection
Solution
The pipe has fluidic
while the display value
hasn’t changed
Please check if the
blade is stuck by
debris
Display Type: Please remove the
one screws on the side of Fig. 6
above; then please
counterclockwise remove the
display of Fig. 5, and then loosen
the four screws of Fig. 4 to clean
the body blade of Fig. 3.
Non-display Type: The body
blade of Fig. 3 can be removed
and cleaned by loosening the four
screws of Fig. 4.
(When cleaning the blade, a
small brush adding some water
for cleaning is recommended.)
Inaccurate
measurement
Please check the
parameters
Please check if the setting
parameters and K value
have been changed, and
check if the flow display unit
is correct.
No display or no signal
Please check the
power supply and
connector
Please check if the input power is
DC10~32V and the quick
connector is locked properly. If
the above steps are executed,
but problems cannot be solved,
please contact the sales
representative

4.7 Mounting location
◼The straight pipe must be long enough on the upstream side and downstream side
where the flow meter is installed. This can obtain an evenly distributed and stable flow
field so as to guarantee the measuring accuracy. When installing the flow meter, please
choose optimal distance based on the pipe dimension and field environment. Generally,
the longer the section of the straight pipe is, the better. The table below lists the
minimum distance based on the times of D (D=pipe diameter).
