Gas utility meter optical reading
Natural gas and LPG meters at boilers, kitchens, kilns and furnaces usually have a mechanical register and no output. A camera reader photographs the digits and the cloud AI model records the register, so fuel use reaches your reports daily.
THE PROBLEM
Fuel is a big bill read once a month
Gas is one of the largest energy costs for kitchens, laundries, foundries, ceramics and process heating. Yet many sites read their sub-meters monthly, from a meter in a ventilated cabinet or an outdoor regulator skid, and never see how use changes with shifts, batches or weather.
Gas meters are also the hardest instruments to replace. The pipework is regulated, the work needs a qualified gas engineer, and the meter may belong to the supplier. Fitting a pulse output often means a meter change anyway.
Reading the register optically leaves the gas train untouched. The question is where the meter is and what the area classification around it requires, and that is where we start.
HOW WE SET IT UP
Compatibility first, then cameras
Meter face assessment
We look at the register type, the window, and how the meter is housed. Diaphragm and rotary meters with rolling digits are typical candidates.
Area classification review
Meters near regulators and vents can sit in a classified hazardous zone. We review the zone with your safety team and specify a suitably rated installation or a mounting point outside the zone.
Readings into energy reports
Register values become daily gas consumption, which can be converted to energy and set against production, covers served or degree days.
Image kept as evidence
Every value carries the photo it came from. When a supplier bill and your figure disagree, you have the register image for that date.

FAQ
Questions buyers ask us
Can a camera read a gas meter safely?
Yes, with the right installation. The camera leaves the gas train untouched, and if the meter sits in a classified hazardous area we specify a suitably rated installation or a mounting point outside the zone, agreed with your safety team.
Do I need permission from the gas supplier?
The reader mounts beside the meter, so the meter and its seals stay exactly as the supplier left them. It is still good practice to check any supplier rules for the meter location, which we cover during the survey.
What types of gas meters can be read?
Meters with a visible mechanical register, such as diaphragm and rotary meters, are the usual fit. We assess each meter face and its housing from photos before quoting.
How is the data used?
Register readings become daily consumption in RIOD Live or on your own server. Teams use them to track fuel per batch or per shift and to check supplier bills.
Need daily gas data from existing meters?
Share photos of the meters and where they are installed. We will assess the fit, including any hazardous-area needs, and propose a pilot.
