More about the meter
What kind of meter is at my home or business?
The gas meter at your home or business is a one-way communication meter using Automated Meter Reading technology and an Encoder Receiver Transmitter (ERT) to remotely, safely and securely send lower-power radio signals (meter data) to our meter readers.
Our meters are equipped with different types of ERTs depending on several factors, and all operate on a +24 dBm output-power radio frequency.
As of May 2024, we added ultrasonic meters to our suite of residential meters. This meter is about 70% smaller than traditional, mechanical residential meters and features a digital reading display, and new internal safety shut-off valve. This meter, shown below, uses the same ERT as mechanical meters, but it is encased within the meter body.
This new meter is called "ultrasonic" because it measures the passage of gas ultrasonically via vibration in sound waves that travel from end of the meter to the other.

How is my meter data communicated to meter readers?
During the three-day billing window, we deploy trucks to “read” the meters via lower-power radio transmitter signal. Our trucks are equipped with a data collector that receives meter data within a 902-928 MHz band. Meter data is then exported to and connected with our billing records to ensure the most accurate billing.
No protected personal information is transmitted to or from your meter.
Is my meter a smart meter?
No, the NW Natural meter is an AMR (Automated Meter Reading) meter, which uses one-way communication. A smart meter uses two-way communication to continually transmit data back and forth between a customer and utility. AMR meters are powered by a battery and emit lower-power radio frequency, much lower than FCC guidelines. There are no demonstrated health effects resulting from the meter’s low-power radio frequency.
You can read more about the Itron AMR meters we use at the Itron website below under Sources.
Can I ask NW Natural to remove the ERT from my meter?
Yes, you have the option for NW Natural to remove the ERT, at your expense. The minimum charge for removing an ERT is $172, plus ongoing monthly charges, which cover manual gas meter readings.
Can I ask for an ultrasonic meter, or opt out of receiving one?
No. One cannot select the meter model. However, if you already received an ultrasonic meter and want it removed, you can request to replace the ultrasonic meter with a mechanical meter and remove the ERT, at your expense. The minimum charge for removing an ERT is $172, plus ongoing monthly charges, which cover manual gas meter readings.
