About the entity

Diehl Metering
Company specialized in smart metering systems engineering and engineering services. Provides the complete process chain from measurement to invoicing, including services and solutions enabling to tackle Non-Revenue Water or drive asset management.


The figures are unquestionable: more than 3 billion people worldwide do not have access to drinking water, and by 2025, approximately 1.8 billion people will live in water-scarce regions. Several factors explain it: diminishing groundwater reserves, massive agri-food industry, inadequate or obsolete distribution infrastructure, lack of waste water treatment, excessive resource consumption, resources available free of charge, etc. As a consequence, groundwater is becoming depleted faster than it can be replenished. A World Bank report published in May 2016 suggests that water scarcity, exacerbated by climate change, could cost certain regions up to 6% of the domestic product growth.

The main water management challenges are a global concern: they concern all countries, all continents and all sectors of activity, from the public sector, industry and businesses, to the end user.

Diehl Metering offers a reliable and sustainable solution for water management: Smart Metering

The total estimated cost of water losses in the world is 68 billion dollars per year (source: Liemberger and Wyatt NRW figures for 2018, Miya Arison Group). Non revenue water is water produced but 'lost' before it reaches the consumer due to several reasons: leaks, inaccurate metering, fraud or poor network management.

Meters and other measuring equipment communicate using Diehl Metering radio technologies for automatic reading (AMR - automatic meter reading / AMI - advanced metering infrastructure). New technologies, such as LoRa or NB-IoT, are also available, for greater flexibility. Associated software, such as IZAR PLUS PORTAL (a very safe data hosting service, ISO 27001 certified), provides strategic data to make decisions on network maintenance and configuration.

Diehl metering solutions have proven their worth in different world regions: enhanced network performance (optimised costs), water savings (non revenue water reduction), optimised billing (no estimations) and reading performance (100% of readings completed, billions of data treated). The experience and reliability of Diehl Metering reflect and now expand to the concepts of smart city, smart industry and retail businesses.
