IoT Applications with Impulse reading

Power, water, gas, heat or similar remote consumption readings with impulse output.
Analysis of consumption savings and dynamic advance billing.
Detection of media leakage or sharp consumption change (water, gas leakage).
Irregular (volume based), daily or more frequent readings (15min-24h intervals)
Monitoring of load or overload of machines or equipment (with detection of short-term peaks)

SENSECOM-IMD (IMDS, IMDBS), IMN

IoT communication unit key features:

Remote consumption reading of electricity, water, gas, etc. using impulse sensor
Primary input – S0 impulse input
- impulse reading from power-meter (billing or secondary) or other meter having S0 impulse input
- S0 – galvanically separated 4,5kV (separately powered optron)
- Supports 2-level tariffs (differentiation by grounding to neutral wire)
Secondary voltage-free impulse input
- reading from a gas meter / water meter equipped with a voltage-free contact (or open collector connection, max 0.5V at max 0.5mA at closed state)
Broadcasting to the nationwide network:
- SIGFOX (models IMD)
- NB-IoT (models IMN)

DIN rail (width 3U), IP20
powered from the mains, backup 1h by supercap or extended to 24h*
Input for electronical seal*
Manipulation detection (accelerometer)
Linkable to repeater SENSECOM-WSH for hard-to-reach SIGFOX places (metal cabinets, shafts, basement, etc.) – aplicable for IMD models

* optional models

SENSECOM-IMT, IMHN

IoT communication unit key features:

Remote consumption reading of electricity, water, gas, etc.
Primary inputs:

- CNT0, CNT1 – voltage-free* impulse reading input from meters
  - CNT0 input can separate impulses into 2 counters based on media flow direction using DIR input
- DIR – voltage-free* input applied for media flow direction resolution
- DI – voltage-free* digital input (no galvanic isolation), applied for eg. flood detection

*Alternatively, an open-collector output limited to max. 0.5 V at max. 0.5 mA in the closed state can be connected. There is no galvanic isolation of input.

Broadcasting to the nationwide network IoT networks:
- SIGFOX (models IMT)
- NB-IoT (models IMHN)
