AmbiPower
Smart metering and smart grid solutions for utilities
The utility & metering business of Ambimat Electronics — reading meters remotely and bringing field data into operations.
Powering the next stage of utility transformation
Utilities are moving from periodic, manual data collection toward connected operations — and most need a route that starts from the infrastructure they already run.
Reading is slow and manual
Reading meters by hand is costly and error-prone, and it limits how often a utility actually sees its data.
The field is hard to see
Distribution networks are harder to run without visibility into what is happening on feeders and at substations.
Replacement isn't realistic
Most utilities need to modernise on top of their existing meter estate rather than replace everything on day one.
The utility & metering business of Ambimat Electronics
Established in April 1982, Ambimat has 44 years of experience. AmbiPower is its utility and metering business, serving power, water and gas distribution utilities from Ahmedabad, Gujarat, India.
Our mission
To help utilities minimise losses and improve quality of service with practical metering and smart-grid solutions.
Our approach
We focus on solutions that build on the infrastructure a utility already has — reading existing meters, and bringing field data into operations — rather than requiring a wholesale replacement to get started.
AmbiPower
Two problems we help utilities solve
Getting readings out of meters
Reading meters by hand is slow, costly and prone to error, and it limits how often a utility sees its data. Automated and mobile reading collect data without a manual visit — and can be added without replacing the meter.
Bringing field data into operations
Distribution networks are harder to run without visibility on feeders and at substations. Instrumenting the network — so field equipment reports status and measurements back to operations — is the basis for a smarter grid.
Five products, two solution lines
Retrofit Module
A cellular automatic meter reader that reads a utility meter — water, gas or energy — and forwards readings to the utility's Head End System over a mobile network, so meters can be read remotely without a field visit.
- ›Reads water, gas or energy meters in the field
- ›On-device processing to reduce data sent over the network
- ›Scheduled, on-demand and long-window meter reads
- ›Event-based SMS notifications
Sits at the meter, reads it locally and communicates with the utility's Head End System over cellular — fitting an existing metering estate without replacing the meter.
UDR App
A mobile app that reads meters through the optical port and sends readings to the utility's billing servers. It stores readings on the device and uploads them later, so a constant data connection is not required at the meter.
- ›Reads meters over the optical port from a standard mobile device
- ›Works with single-phase and three-phase meters
- ›Stores readings on the device, uploads when connected
- ›Replaces paper-based meter reading
Runs on a standard mobile device carried by a meter reader, delivering data to the utility's billing system — replacing manual transcription of readings.
Available on Google Play.
DESU — Data Extraction & Storage Unit
A gateway that collects data from field devices over a range of communication buses and forwards it to a SCADA server over a LAN or cellular connection — the layer between on-field equipment and the utility's software platform.
- ›Collects data from field devices over multiple communication buses
- ›On-board buffering so data is not lost during outages
- ›Forwards data to a SCADA platform over LAN or cellular
Sits between field devices and the SCADA platform, gathering data on site and delivering it upstream so field data reaches operations systems reliably.
Remote Terminal Unit (RTU)
A modular, scalable controller that connects digital and analog field devices back to the SCADA system and forwards their data to the SCADA backend over a LAN or cellular connection.
- ›Interfaces with digital and analog field devices
- ›Modular, scalable input / output
- ›Backhaul to SCADA over LAN or cellular
Installed in the field or at a substation, it interfaces with local devices and relays their status and measurements to the control room's SCADA system.
RST Reset Unit
Monitors the environment of an IT-rack and RTU and lets the power be reset remotely over SMS or LAN, with temperature monitoring and SMS / e-mail alerts. (“RST” refers to the Reset Unit.)
- ›Ambient temperature monitoring of the IT-rack
- ›Remote power reset over SMS and LAN
- ›SMS and e-mail alerting with a reset audit trail
Installed with the IT-rack or RTU it watches. It reports temperature and status, raises alerts, and lets an operator restart equipment remotely rather than travelling to site.
Move from periodic collection toward connected operations
Reading meters by hand is slow, costly and error-prone. AMR collects readings without a manual visit; AMI adds two-way communication. AmbiPower supports reading in two complementary ways — cellular at the meter, or over the optical port from a mobile device.
- ›Automated or mobile reading instead of manual transcription
- ›A digital path from meter to billing
- ›A staged route that builds on the existing meter estate
Bring the field into the control room
Instrumenting the network — so field equipment can report status and measurements back to operations — is the basis for a smarter grid. AmbiPower provides field devices that bring data back to the control room over LAN or cellular.
- ›More visibility of field equipment in the control room
- ›A path to bring distributed sites into SCADA
- ›Fewer site visits to recover monitoring equipment
From the field, into operations
Where the products earn their place
Turn meter reads into clean, timely data for billing.
- ›Retrofit automated reading onto existing meters
- ›Remote reading where field visits are costly
- ›Remove transcription errors from the billing feed
Cut the trips field teams make to reach equipment.
- ›Walk-route reading without fixed comms at the meter
- ›Reading in areas with intermittent coverage
- ›Recover an unresponsive RTU without a site visit
Give operators visibility of distributed field assets.
- ›Concentrate substation & feeder data for SCADA
- ›Extend SCADA visibility to distributed sites
- ›Watch rack temperature at unstaffed sites
What a utility can reasonably expect
Less manual work
Automated or mobile reading instead of manual transcription.
A cleaner data path
A digital path from meter to billing, with fewer transcription errors.
More field visibility
More visibility of field equipment in the control room.
Fewer site visits
Fewer trips to recover monitoring equipment in the field.
Builds on what you have
A staged route that builds on the existing meter estate.
A path to AMI
Coverage can be extended over time as part of a move toward AMI.
A staged, low-risk path to adoption
Scope is defined together and depends on your environment and objectives. Each stage builds on the infrastructure already in place.

The portfolio at a reference level
Choosing how meters connect
There is no single right answer — cellular and RF mesh both work, and many utilities use a mix. Match the technology to the area, then confirm with a survey before rolling out.
Each meter connects on its own over existing mobile networks — suits meters that are spread out. Low-power options (NB-IoT, LTE-M) trade throughput for reach and low power, a good fit for small, infrequent messages.
Meters relay data for one another toward a data concentrator, which shares a smaller number of upstream connections — suits dense areas where meters are close together and can relay for each other.
