3. Product description
3.1 Data label
The data label includes the following information: product model type, power supply voltage,
output type, operation temperature/pressure and other specifications
3.2 Contents of factory shipping carton
Verify and inspect the contents you have received to ensure it is what you
ordered/requested.
A. Product (Paddlewheel flowmeter)
B. M12, 8Pin electrical cable
C. Documents
Operation manual
Inspection certificate for measuring accuracy (optional)
3.3 Product introduction
The principle of operation of the paddlewheel flowmeter uses the paddlewheel blades
rotation to measure the flow velocity, based on which the flowrate is calculated. The ERP1
paddlewheel flowmeter consists of the flow sensor/transmitter and the T-fitting pipe. With its
compact design, the unit is very easy 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 0.3~10m/s (1.0~30ft/s). 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 an operator or
user may conveniently read this data.
3.4 Product applications
The ERP1 can be used in a variety of industries; food and beverage, water treatment,
pharmaceutical, dyeing, chemicals, semi-conductor and PCB wet process control.

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
two 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
DC24V 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
When installing the EPR1 paddlewheel flowmeter be sureto provide minimum
upstream and downstream straight pipe run lengths for optimal performance and
accuracy. Refer to the below illustrations for minimum straight pipe
run lengths, specified in terms of a multiple of the pipe diameter
(DN25 / 1” or DN50 / 1½”).

The paddlewheel flowmeter can be installed in either a vertical or horizontal orientation.
The following requirements must be adhered to:
1. For horizontal installations the paddlewheel flowmeter must always be installed
level and not on an incline.
2. For vertical orientations the paddlewheel flowmeter should always be installed
“plumb” and not on a slope or incline.
3. The paddlewheel flowmeter should only be used in full pipe conditions.
4. Eliminate entrained air within the fluid flow as this may affect the measurement
accuracy of the paddlewheel flowmeter.

※Notes：
※Installation in the horizontal orientation must have the paddlewheel blade hanging
“down” into the T-fitting, NOT mounted with the blade pointing up into the T-fitting..
※Ensure that the installation is within the paddlewheel flowmeter specifications for
materials of construction, pressure and temperature.
※Select the appropriate pipe diameter based on the flow/velocity/pipe diameter.

5. Wiring instructions
5.1 Safety
1. Ensure that power to the paddlewheel flowmeter is disconnected so wiring is
performed only in power-off status.
2. Check to make sure that the power supply meets the power supply voltage
requirement specifications of the paddlewheel flowmeter.
3. If it is possible that the input power voltage might exceed the paddlewheel
flowmeter specification voltage please install an overvoltage protection device to
protect the paddlewheel flowmeter.
