Honeywell’s ER 350 simplifies pressure monitoring

Local gas distribution and transmission companies utilize Electronic Pressure Recorders to monitor pressure in the Gas distribution and transmission grid. Electronic Pressure Recorders are a key element in the gas value chain, contributing to the security and availability of gas within the gas distribution network.

Honeywell’s ER 350 Electronic Pressure Recorders are intended to simplify and optimize pressure monitoring applications. This new Pressure Recorder, based on the EC 350 electronic corrector platform offers best-in-class accuracy, expanded memory, advanced diagnostics and integrated cellular communications. The ER 350 also reduces maintenance requirements and is intuitive and simple to use.
