Page 3: Product Description
2.1 O PERATING PRINCIPLE IZAR PULSE i is a ring equipped with a sensor based on the inductive principle and with a specific electronic system that exploits the information to be transmitted in the form of an open-collector signal (polarised). -
Page 4: Characteristics Of The Pulse Output
RECAUTIONS OF USE It is essential to observe the polarity and supply voltage in order to generate proper usable signals and protect IZAR PULSE i from any damage (if supply exceeds 30V/50mA). Refer to the label on the product. Diehl Metering declines any liability in the event of non-observance of the installation instructions. -

Page 8: Standard Version
IZAR PULSE i 3-wire takes into account the flow direction by compensating negative pulses. In case of a backflow, IZAR PULSE i 3-wire will emit no pulse. When the flow goes back to normal, IZAR PULSE i 3-wire starts emitting pulses again only once the volume of backflow has been compensated for (up to the limit of 65,535 pulses). -
Page 9: Izar Pulse I 4-Wire - Standard Version
WIRE STANDARD VERSION IZAR PULSE i 4-wire provides information on the volumes of water transiting in both flow directions (subject to the use of suitable electronic processing). The exploitable electric information is transmitted via a cable with 4 insulated conductors. -

PECIFIC VERSIONS 4.1 IZAR PULSE DRY CONTACT IZAR PULSE i dry contact version can be connected to most standard equipment on the market (CTM...). Connection IZAR PULSE I - DRY CONTACT IZAR PULSE i Dry contact features 2 non-polarized output wires. Therefore, it may be connected in any direction (yellow and green wires). -

WIRE VERSION OUTPUT WITH CONFIGURABLE PULSE WEIGHT Connection IZAR PULSE i 4-wire - 1 output with configurable pulse weight It is essential to observe the polarity and supply voltage in order to generate proper usable signals and protect IZAR PULSE i from any damage. -
Page 13: Izar Pulse I - 2 Outputs With Configurable Pulse Weight + Fraud
OUTPUTS WITH CONFIGURABLE PULSE WEIGHT FRAUD IZAR PULSE i « 2 outputs + fraud » enables to generate pulses on 2 different wires and to use the 3rd wire for “fraud” detection Information can be sent simultaneously on 2 different devices while maintaining a monitoring on tampering (unclipping or cable cut). -
Page 14: Izar Pulse I - 2 Outputs With Configurable Pulse Weight + Flow Direction
OUTPUTS WITH CONFIGURABLE PULSE WEIGHT FLOW DIRECTION IZAR PULSE i « 2 outputs + flow direction » enables to generate pulses on 2 different wires and to use the 3rd wire to determine the direction of the water flow. The direction wire is linked to the output 1. The output 2 compensates for negative pulses and only sends positive pulses. -
Page 15: Izar Pulse I - 2 Outputs With Forward And Reverse Flow Direction + Fraud
OUTPUTS WITH FORWARD AND REVERSE FLOW DIRECTION FRAUD IZAR PULSE i « +/- » enables to generate pulses on 2 outputs: 1 positive output and 1 negative output and to use the 3rd output for the “fraud”. It is therefore possible to send information on the volume of incoming and outgoing water on the same device while keeping information on tampering (unclipping, cable cut…). -
Page 16: Izar Pulse I - 2 Outputs - Forward And Reverse Flow Direction + 1 Specific
FORWARD AND REVERSE FLOW DIRECTION SPECIFIC IZAR PULSE i « +/- » enables to generate pulses on 2 outputs: 1 positive output and 1 negative output and to use the 3rd output for an additional pulse. It is therefore possible to send information on the volume of incoming and outgoing water on the same device while keeping an output for billing. -
Page 17: Izar Pulse I - 3 Outputs With Configurable Pulse Weight
4.7 IZAR PULSE OUTPUTS WITH CONFIGURABLE PULSE WEIGHT IZAR PULSE i 3 outputs version enables to generate pulses on 3 different wires. Information can therefore be sent to 3 devices simultaneously, such as an external radio, a dosing pump and a display unit. -
Page 18: Installation Precautions
NSTALLATION PRECAUTIONS 5.1 I DENTIFICATION Make sure that IZAR PULSE i is compatible with the meter on which it is clipped (marked “Ti” or “Ha + Ti”). 5.2 I NSTALLATION If there is a cover on the meter, take it off by pushing out the hinge pin. If the cover does not have a metal hinge, remove it by hand. -
