FIELD TELEMETRY · PROTOCOL TRANSLATION

Telemetry for the Sites

Everyone Else

Copper lines are disappearing. Cellular is unreliable. Manual reads are a safety risk. FlexPT creates a private LoRa network that connects your legacy EVC devices to modern MQTT infrastructure — in minutes, with no SIM card and no recurring carrier fees.

THE PROBLEM

Three Problems.

One Device.

Copper is disappearing.

Carriers are retiring the copper lines telemetry was built on. Sites that worked for decades are going dark — with no clear replacement path.

SOLVED BY FLEXPT

Cellular is inconsistent.

Rising carrier fees and unreliable coverage routinely leave critical sites offline. Spotty signal in basements, vaults, and remote locations makes cellular an unreliable foundation.

SOLVED BY FLEXPT

Manual reads are risky.

Every walk-up puts a person at a live gas site. Fewer visits mean safer people and safer property — but only if you have an alternative.

WHAT IT DOES

Drop-In Telemetry

That Just Works.

Connects Directly

Popular gas correctors and pressure recorders via dual RS-232 serial ports.

Translates Instantly

Major EVC protocols into modern MQTT / Sparkplug B payloads.

Private LoRa Network

No SIM cards, no carrier contracts, no recurring fees. License-free sub-GHz radio.

Secured End to End

Every payload protected with TLS-encrypted MQTT.

Deploys in Minutes

No programming, no drivers, no proprietary polling software.

Configures from a Browser

Built-in web interface with live serial data and gauges — nothing to install.

FIELD PROVEN

Field Proven. Secure.

Certified.

FlexPT's private LoRa link is validated in live, real-world field testing. Typical coverage reaches 1 mile or more, with relay node range extension available for challenging terrain.
