Zenner GPRS/NB-IoT Smart Diaphragm Gas Meter - Remote Valve

Description

The transition to smart metering requires hardware that is both technologically advanced and metrologically sound. The Zenner GPRS/NB-IoT Smart Diaphragm Gas Meter is built upon the foundation of a high-quality ZENNER mechanical diaphragm gas meter. This ensures that while the communication is digital, the underlying volume measurement retains the long-term stability and reliability that the industry trusts.

The core innovation of this device lies in its integrated smart controller equipped with a GPRS/NB-IoT communication module. NB-IoT (Narrowband Internet of Things) is particularly advantageous for gas meters as it offers deep signal penetration into basements or shielded areas where meters are often located. This ensures consistent data delivery to the central server without the need for complex gateway infrastructure.

Furthermore, safety and management are significantly enhanced by the built-in shut-off valve basement. This feature allows utility operators to remotely close the gas supply in the event of a detected leak, emergency, or for administrative purposes. By combining measurement, communication, and flow control into a single unit, this smart meter reduces installation complexity and operational costs.

Brand

Zenner

ZENNER gas meters impress by the solid processing of high-quality materials combined with a large number of technical details. In the manufacturing process we purely use materials of the highest quality that meet the requirements for product lifetime, security and technical precision.

For example, the housing of our diaphragm gas meters are made of high quality steel or aluminum. The raw material of the essential parts are imported from Europe.

In addition we purely use tested component connections to guarantee that the meters are solid, safe and leakproof. The corrosion resistance is ensured by the use of galvanized steel and die-casting aluminum. In addition to meters are mainly used in residential, commercial and industrial settings.
