AES-ZA smart diaphragm gas metering
Precise measurement, remote monitoring and reliable gas metering.
Solid build quality, high accuracy and advanced technical details make the AES-ZA diaphragm gas meter a high-grade measuring instrument. It provides precise measurements, consistent measuring stability, a long service life and high reliability. High-grade materials help make the meter resistant to corrosion.
The AES-ZA smart diaphragm gas meter combines the AES-ZA mechanical diaphragm gas meter with a built-in shut-off valve and a smart controller with a communication module.
Suitable for natural gas, town gas and other gases conforming to EN 437.
The product overview states a lithium battery life of more than 10 years. The specification lists a standard battery life of 10 years; actual service life depends on installation location, signal coverage and ambient temperature.
