Product Description

The multipath meter with multiple advantages

The ultrasonic meter USM GT400 from RMG delivers highest accuracy and reliability based on field proven six path technology. Designed for use in a wide range of gas custody transfer and secondary metering applications, the GT400 measures directly bulk flow rate, swirls, cross-flow and asymmetry. Its patented live precision adjustment/echo measurement reduces metering uncertainty.

Proven Technology. Superior Performance.

A Better Solution

RMG’s USM GT400 is an intelligent
ultrasonic flowmeter which meets
today’s strict requirements for
accurate and stable measurements
in gas industry operations. It’s
a multipath meter with multiple
advantages: a field-proven
electronics, sophisticated
diagnostics, user-friendly software
to monitor the health of the flow metering system and a superior          six-path measuring technique. RMG’s six-path technology has been proven in demanding applications across the industry for more than a decade.

Proven Technology

Today, intelligent solutions are needed to measure and analyze the quality and volume of natural gas at every stage of its movement, storage and utilization. Gas industry organizations can meet this requirement with RMG’s Regulating and Metering product lines, which are available individually or as complete systems for gas metering stations. RMG by Honeywell has more than 150 years of experience, supplying solutions to the major gas transmission companies in Europe and Asia.

Application Know-how

We partner closely with industrial,
commercial and gas distribution
customers to provide the right flow
measurement solution to optimize
operations at gas-fired power plants,
liquefied natural gas (LNG) storage and
export terminals, city gate facilities,
petroleum refineries, metals and mineral
processing plants, combined heat and
power generation facilities, and all sites
utilizing natural gas as a feedstock.
