Smart Meters and Concerns about Overcharging

There has been a growing resistance to meters in regions worldwide. Many customers believe that their utility bills have surged following the installation of these devices. The main source of discontent stems from the shift from electromechanical meters to new smart meters. Let's take a look why this perception persists and how utility companies can tackle these issues through on site accuracy tests using our RS350.

Differentiating Between Old and New Meter Technologies

Electromechanical (Ferraris) meters which have been in service for years often experience wear and tear over time. One common problem is the rotating disk inside the meter coming into contact with the braking magnet. This contact leads to a scratching sound and causes the meter to slow down, resulting in an underestimation of energy consumption. In some instances inaccuracies can reach, up to 10% or more.

On the hand, new smart meters are engineered for precision, usually operating within +/ 1% of actual energy usage. They are finely calibrated to meet accuracy criteria, ensuring that customers are billed correctly for their energy usage.
The shift, from using an electromechanical meter to a precise smart meter may give the impression that utilities are charging too much.

Why Accurate Metering Matters

Having meters is essential for both consumers and utilities. For consumers, fair billing helps build trust and satisfaction. Utilities rely on data for managing the grid planning and promoting energy efficiency. The move to meters is important for reaching these objectives. It needs to be handled carefully to address consumer worries.

Addressing Consumer Worries

To ease concerns about overcharging, utilities can take steps;

  • Open Communication
    Educate consumers on the differences between old and new meters and how wear and tear affects accuracy in older models.
  • On Site Accuracy Tests
    Conduct on site accuracy tests using certified testers like our RS350. These tests can demonstrate the precision of the meters compared to the older electromechanical ones.
  • Customer Support
    Provide strong customer support to address any questions or worries consumers have about their new meters and billing.

On Site Accuracy Testing with RS350

Our RS350 is a certified tester specifically made for conducting, on site accuracy tests for meters. By utilizing this device utility companies can validate the precision of both meters offering clear results to customers. The RS350 is designed to pinpoint and correct any discrepancies, enhancing consumer trust, in the switch to meters.


Transitioning from meters to smart meters is an important move for ensuring accurate and equitable billing practices. While concerns regarding overcharges are valid, they can be alleviated through communication and on site accuracy assessments conducted by certified technicians like those using our RS350 device. By following these steps, utility providers can maintain consumer confidence while upholding the reliability of their metering infrastructure.
