Why Choose ATLAS Single-Jet Water Meters?

ATLAS EC20 and EH20 mechanical single-jet water meters are designed for accurate, reliable hot- and cold-water consumption measurement. Single-jet technology, Class 2 accuracy and high repeatability support monitoring in homes, commercial buildings and central distribution systems.

A durable brass body and PN16 rating accommodate different installations. The EC20 cold-water model has a T50 temperature class, while the EH20 hot-water model is T90. Model-dependent IP54–IP65 protection options allow selection for the application environment.

An easy-to-read register, rotatable through 180° on some models, simplifies meter reading. M-Bus, pulse and LoRa/LoRaWAN communication options allow use with ATLAS CNV data collectors and LoRaWAN gateways for central reading and remote consumption monitoring.

ATLAS EC20 and EH20 mechanical single-jet water meters

The ATLAS EC20/EH20 series water meters are high-precision meters designed to measure hot and cold water consumption. They are manufactured from brass. They offer high repeatability and measurement accuracy. Designed to integrate with any type of automation and remote reading system, they feature built-in and optional communication systems (M-Bus, Pulse/Output, LoRa/LoRaWAN). ATLAS CNV data loggers can be used with a LoRa Gateway.

The temperature class is T90 for the EH20 and T50 for the EC20.
