Measurement Devices

At Romet, our measurement devices are engineered to provide critical endpoints that deliver accurate and reliable gas path data throughout the natural gas transmission and distribution system. By utilizing our devices, operational efficiencies are optimized, providing a foundational step to accessing a wealth of data for informed decision-making.

 

  • RMT and RM rotary meters generate natural gas flow measurement,
  • Ideal for commercial and industrial applications (600-56,000 cfh, 16-1600 cmh),
  • Patented pinned timing gear design for precision measurements.


RMT Rotary Meter Series

Principles of Operation

Romet measurement devices employ positive displacement rotary technology, which utilizes the rotation of two figure-eight shaped impellers for measurement. These impellers, mounted on low-friction bearings and positioned at 90 degrees to each other by precision timing gears, contra-rotate in semi-cylindrical housings enclosed by head plates. Close tolerances and timing gears ensure an effective capillary seal while preventing contact between the impellers and housing. As gas enters the meter's inlet, a pressure differential between the inlet and outlet causes the impellers to rotate, displacing a precise volume of gas with each revolution. This volume is transmitted to a readout module which allows the collection and organization of data.

Diaphragm Conversion Kits

Romet's diaphragm meter change-out kits offer an effortless transition to our edge point devices, a superior platform for data generation, accumulation, and transmission. 


Our conversion kits are pre-sized, factory-tested, and require no welding or pipe cutting, enabling easy installation with common field tools by one or two-person crews. This dramatically cuts field installation costs and scheduling.
