Meter with Pulse Output

Overview

The CEI 62053-31 standard applies to the following meters:

  • iEM2000T

  • iEM3110

  • iEM3155

  • iEM3210

  • iEM3255

  • iEM3355

  • Meter with pulse output

The meter delivers a pulse output.

The Modbus information in the following table is given for a meter connected to channel 1.

The same channel (Ti24 interface) on the I/O Smart Link can take account of two meters:

  • One meter connected to input I1

  • One meter connected to input I2

(1) To address the channel N (1≤ N ≤ 11) registers, add 40 × (N – 1) to the channel 1 registers.

(2) The register contains the flow value.

  • The flow is: (3600 x pulse weight)/t, with t representing the time in seconds between two pulses. The result is expressed for one hour.

  • The pulse weight is 10 by default. The unit depends on the connected device: energy, gas, water, for example.

(3) The consumption value (associated with a channel) is obtained by multiplying the number of pulses (received by inputs I1 and I2 of this channel) by the pulse weight.
