ITM-MAGMETER-T500-ED2

Induction ﬂ ow meter T-500 is designed for measuring both clean and waste water in water management

applications.

The instrument is characterized by high accuracy and stability of ﬂ ow rate measurement in whole range of

ﬂ ow rates from 0.1 to 10 m/s in both directions.

Measured values are displayed on a large graphical display, which is standard component of the instrument

as well as a keyboard and three programmable isolated outputs for remote transmission of measured values.

Two of them can be used as pulse or status outputs and the third one as an active current output. The stan-

dard delivery includes also an internal datalogger and RS232 communication port.

A GSM module for remote data reading via SMS text messages can be ordered as an option.

Setting of ﬂ ow meter parameters is performed using the keyboard and intuitive display menu or using service

software via RS232 communication port.

If the instrument has been disconnected from power supply for period longer than 6 months, the internal clock

battery can be empty. It is recommended to check time and date when putting the instrument in operation after

longer downtime.

The battery will be automatically charged after the instrument has been connected to power supply.

To ensure the proper function of the instrument, the measuring section of the induction ﬂ ow meter sensor –

measuring tube – has to be completely ﬂ ooded with the measured liquid and the measuring section cannot be

inﬂ uenced by any disturbing elements as valves, pumps, bends or sharp deviations in the tubing section.

Therefore, observe the following instructions when installing the ﬂ ow meter into the tubing:

If the system includes pumps, never place the ﬂ ow meter sensor into the pump intake (A)! 1.

Place the ﬂ ow meter sensor into the lowest point of the horizontal part of the tubing or into the ascendant 2. tubing (B); never place the sensor into the tubing in the ﬂ ow top-down direction (C)!

Ensure that steady (straight) parts of tubing are min. 5 x DN before the instrument and 3 x DN behind the 3. instrument (D).

Tubing reductions with slope up to 8° are considered as straight (E). 4.

Prevent the instrument from being exposed to vibrations or direct sunlight (F). 5.

4. Important

5. Location

1. . Ensure that the ﬂ ow sensor frame is connected to ground. Use the ground terminal at the outside of the

sensor for that purpose. This will prevent from undesirable interference, especially for detached versions when

shielding of the link cable between sensor and electronic unit is connected to the frame.

Remove upper cover of the instrument to get access to terminals for power cable and for signal cables.

CAUTION!

Keep on mind that induction ﬂ ow meter is an electric device; so next steps can be performed only by

a qualiﬁ ed person!

3. The induction ﬂ ow meter is powered by mains voltage 230V/50Hz connected to power supply terminal block

labelled as L - PE - N, or by low voltage 12 V DC or 24 V AC connected to terminals labelled L – PE – L.

The polarity of supply conductors makes no difference in case of using the 12 V DC power supply.

Connect the power cable to terminals.

The induction ﬂ ow meter does not have its own On-Off switch so it must be fused and switched on/off in other

device (e.g. switchboard).

The protection of electric circuits is ensured by protective fuse T100mA, or 1A for the 12 – 24 V version, located

next to 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.

2. Connect the ﬂ ow 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 labelled 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. La longitud estándar del cable

de interconexión entre el sensor y la unidad electrónica es de 6 metros. El cable de interconexión está incluido

en el envío.

Maximum length of the link cable is 25 meters (optional). The link cable should be always connected before

power supply is connected to the transducer.

If the power cable has been already connected to the transducer, connecting and disconnecting of the link cable

when the transducer is under voltage is prohibited.

Internal datalogger enables recording of measured values in chosen intervals either periodically or once at a

time and their storing in instrument memory.

Stored values can be subsequently read on the display or on a PC via RS232 communication link.

The datalogger records following parameters by default: total volume in positive direction V+, total volume in

negative direction V-, instrument status at the moment of reading Exx and real time at the moment of reading t.

Alternatively you can choose recording of one of additional values: immediate ﬂ ow rate Q, maximum ﬂ ow rate

during chosen interval MAX, minimum ﬂ ow rate during chosen interval MIN or average ﬂ ow rate during chosen

interval AVR.

All samples containing above mentioned data are stored in memory as a single record.

Capacity of the sample memory is 100 records. Samples are recorded step by step and they are assigned

addresses from 1 to 100. After recording of 100 samples, the oldest sample with address 1 is deleted, memory

is readdressed and the new sample is inserted to address 100. The memory content is not corrupted if power

failure occurs.
