1. description
The induction FM500 is designed for measuring both clean and waste water in water management applications.
The product is characterized by high accuracy and stability of flow rate measurement in whole range of flow rates from 0.33
to 33 ft/s in both directions for liquids ≥ 10µs/cm.
Measured values are displayed on a large graphical display, which is a standard component of the instrument as well as a
keyboard and three programmable isolated outputs for remote transmission of measure values. Two of these outputs can be
used as pulse or status outputs and the third one as an active current output. The standard delivery also includes an internal
data logger and RS232 communication port.
A GSM module for remote data reading via SMS text message can be ordered as an option.
Setting of flow meter parameters is performed using the keyboard and intuitive display menu or using service software via the
RS232 communication port.

5. installation note
If the instrument has been disconnected from it’s power supply for a period of more than 6 months, the internal clock battery
may be empty. It is recommended to check the time and date when putting the instrument into operation after extensive
downtime.
The battery will be automatically charged after the instrument has been connected to the power supply.
IMPORTANT
6. location
To ensure that the instrument functions correctly, the measuring section of the induction flow meter sensor - measuring tube
- has to be completely flooded with the measured liquid and the measuring section cannot be influenced by any disturbing
elements, such as valves, pumps, bends or sharp deviations in the tubing section.
Please observe the following instructions when installing the flow meter into the tubing:
1. If the system includes pumps, never place the flow meter sensor into the pump intake (A).
2. Place the flow meter sensor into the lowest point of the horizontal part of the tubing or into the ascendant tubing (B);
never place the sensor into the tubing in the flow top-down direction (C).
3. Ensure that steady (straight) parts of tubing are a minimum of 5 x inches before the instrument and 3 x inches behind the
instrument (D).
4. Tubing reductions with a slope up to 8ºare considered straight (E).
5. Prevent the instrument from being exposed to vibrations or direct sunlight (F).

7. electrical connections
1. Ensure that the flow sensor frame is connected to ground (⏚); it is recommended that the ground
terminal at the outside of the sensor is used for this purpose. This will prevent against undesirable
interference, particularly for detached versions when shielding the link cable between the sensor
and electronic unit while connected to the frame.
Remove the upper cover of the instrument to gain access to terminals for the power cable and
the signal cables.

2. Connect the flow sensor link cable to ABCDE ⏚terminals. (Not applicable for compact version, where the sensor was
connected in factory).
Terminal blocks on the sensor and on the electronic unit are labeled identically, so terminals A - A, B -B, C - C, D - D, E - E,
⏚ - GND have to be interconnected. Connect the shielding of the link cable only on the side of the sensor to the ground
terminal on the terminal block of the sensor. Standard length of the link cable between the sensor and the electronic unit
is 6 meters. The link cable is included in delivery. The standard length of the interconnection cable between the sensor
and the electronic unit is 20 feet. The interconnection cable is included as standard with the product.
Maximum length of the link cable is 82 feet (optional). The link cable should be always connected before the power
supply is connected to the transducer.
If the power cable has already been connected to the transducer, connecting and disconnecting of the link cable when
the transducer is under voltage is prohibited.
3. The induction flow meter is powered by mains voltage 230V / 60Hz connected to the power supply terminal block
labelled as L - PE - N, or by low voltage 12 VDC or 24 VAC connected to terminals labeled L - PE - L.
The polarity of supply conductors makes no dierence in case of using the 12 V DC power supply.
Connect the power cable to the terminals.
The induction flow meter does not have its own ON-OFF switch, so it must be fused and switched ON-OFF in another
device, such as a switchboard.
The protection of electric circuits is ensured by protective fuse T100mA, or 1A for the 12 - 24 V version, located next to the
power terminals.
Switch power supply on only after the sensor link cable and external device signal cables are connected!
4. Connect external devices that utilize current output or pulse outputs to terminals BIN1, BIN2, and ANAL. All outputs are
isolated.

8. instrument start
1. When the power supply is switched on, the instrument display shows step-by-step messages POWER ON and TEST INT
CL 1 to TEST INT CL 30.
2. After completing internal tests, the instrument enters to measuring mode. Basic data includes immediate flow rate and
total volume in positive and negative flow directions.
To display the next page, press the button. This page displays the dierence between total volumes DELTA V, total
operating hours from initial start of the instrument and the value of the maximum flow rate 100%FLOW. The next page
displays the highest and the lowest immediate flow rate reached at a particular measuring point.
3. Briefly press the EXE button to display the last line of the data logger. The line number is displayed in the upper-right
corner and its maximum value is 100. Press the or button to scroll up or down a line in the display.
The data logger line (one screen of display) shows time data (date, hour, minute) and total volumes in particular time.
In addition to this data, the instrument will also display one of the following optional values:
Immediate flow rate Q
Maximum flow rate reached during particular period MAX
Minimum flow rate reached during particular period MIN
Average flow rate reached during particular period AVR (Average)
Briefly press the button to return the instrument to basic mode. The instrument will automatically return to basic mode
after approximately 60 seconds of inactivity.

9. instrument configuration
This manual describes configuration of only those parameters that are useful to be changed when the instrument is used in a
typical way.
We do not recommend changing of parameters other than those mentioned in this manual.
Detailed description of software is included in technical documentation for service engineers.
Press the button and hold it for approximately 3 seconds to switch the instrument from ‘Measuring Mode’ to ‘Main Menu
Mode’.
