🧭 Société des Compteurs Métalliques

Historical Origins

The roots of the enterprise go back to 1872, when Gabriel Chamon and Gabriel Nicolas acquired a Paris workshop manufacturing gas meters. The business rapidly expanded during the growth of urban gas, water and electricity networks in France.

In 1881 the business was reorganised as the Compagnie des Compteurs, becoming one of France's foremost manufacturers of utility metering equipment. The board included figures from major French gas-distribution companies, giving it privileged access to rapidly expanding utility markets. Société des Compteurs Métalliques was part of the industrial group that evolved into the renowned Compagnie des Compteurs, one of France's largest manufacturers of utility metering equipment. Originating from a Paris gas-meter workshop established in 1872, the company expanded into water, gas and electricity metering and became a dominant supplier to municipalities, utilities and public infrastructure projects throughout France and the French colonial world. Its products ranged from small domestic volumetric water meters to large Woltmann meters for municipal distribution systems. Manufacturing centred on extensive works at Montrouge near Paris, where thousands of skilled workers produced precision metering instruments noted for their durability and accuracy. Acquired by Schlumberger in 1970, the company's technological legacy continued through Compteurs Schlumberger, Actaris and ultimately Itron, making it one of the principal ancestors of modern utility metering technology.

Expansion into Water Meter Manufacturing

Originally focused on gas meters, the company quickly expanded into:

- Water meters

- Gas meters

- Electricity meters

- Industrial measuring instruments

- Utility control equipment

As French cities developed modern utility networks during the late nineteenth century.

The firm's water-meter production became a major part of its business and was exported throughout:

- France

- Belgium

- Switzerland

- North Africa

- French colonial territories in parts of the Middle East and Asia

Major Manufacturing Sites

The company expanded far beyond its early Paris workshops.

Montrouge became a major factory complex after being established after World War I.

The Montrouge works occupied approximately eight hectares and became one of Europe's largest meter-producing facilities. By the early twentieth century thousands of employees worked there.

Additional manufacturing facilities supported increasing production.

Water Meter Products

The company manufactured a very broad range of water-measurement equipment.

Domestic Water Meters

- Small volumetric meters for residential service connections.

- Rotary and Piston Meters

- Positive-displacement designs used where high accuracy at low flows was required.

- Turbine Meters

Industrial and municipal meters designed for larger pipe sizes and higher flow rates.

- Woltmann Meters

- Large bulk-water meters for waterworks, pumping stations and distribution systems.

- Compound Meters

- Combination meters intended for networks experiencing both low and high demand conditions.

By the late twentieth century it was one of Europe's most important utility-metering groups.

The lineage continued through:

- Compagnie des Compteurs

- Compteurs Schlumberger

- Actaris (2001)

- Itron (acquired Actaris)

This gives the company one of the longest continuous histories in world metering.

Importance in Water Meter History

Société des Compteurs Métalliques/Compagnie des Compteurs occupies a position as one of the foundational industrial meter manufacturers of the modern utility era.

Its products were installed in enormous numbers and influenced metering standards across much of the French-speaking world.

The first water meters

The first water meters, inspired by gas meters, were developed in 1815 by the Siemens brothers, patented in 1820, then experimented in England and Germany. The turbine-powered device that measured the speed of water moving through a pipe and indicated the volume of water moved was found to be unreliable. Perfected, it gave rise to a series of models, such as dry Doris and wet Doris, still manufactured by the CdC in the 1950s.

In France, the first free-flowing water meter, consisting of a tank that was filled and emptied alternately, was built by Mr. Philips and officially installed in Chartres to measure the water supplied by the city to the Chemin de Fer de l'Ouest.

The Kennedy single-cylinder counter inspired the French engineers Samain and Frager. The latter, an engineer at the Maison Michel & Cie in Paris, invented a counter with two horizontal cylinders in 1872, to which he made numerous improvements in 1883 and gave it a vertical shape. Gifted with remarkable precision and sensitivity with his "gout recording", built by the CdC from 1888 onwards, he enjoyed success for nearly forty years.

In the United States, a disc counter designed around 1880, known as the Thomson counter, gave rise to a model improved by the Compagnie des Compteurs (CdC), the Star counter created before 1900. Rotary sub-ring counters, which were also introduced in the United States between 1880 and 1890, were the ancestors of the first odometer of this type, built from 1911 at the CdC under the name Stella, which became Naïade in 1932.
