Sonix® Ultrasonic Meters


No Need for Moving Parts. Or Costly Repairs.

Using digital ultrasonic technology, our Sonix® ultrasonic meters are designed with no moving parts, virtually eliminating the cost of repairs. These meters retain their calibration. They also provide alerts for tampering and for malfunctions. Their compact design affords flexible installation options.

The electronic platform allows you to include automatic meter reading more cost effectively and to upgrade the meter with the latest options while it is still in service.

For remote data collection and storage, Sonix meters feature a pulse output option. The two-wire pulse output enables them to send data to any Form A pulse accumulation hardware. The combination of Sonix meters and remote data collection devices provide a sound solution for today’s growing need for measurement accuracy and lowest total cost of ownership.

Benefits to you

Dig Safely!
Sensus is committed to the safe use of natural gas. That’s why we’ve partnered with the Common Ground Alliance to mark all gas meters sold in the United States with a “Call 811 Before You Dig” decal. It’s a simple way to educate and remind homeowners to make sure underground lines are marked before digging—to avoid damage or injury.
