Brand new
FTM-LNGmass series Coriolis force mass flow meter
YesDesigned for LNG (Liquefied Natural Gas)Mass flow meter designed and developed
LNGmass is a Coriolis mass flow meter specially developed for liquefied natural gas (LNG) dispensers, even whenprocess temperature –196 °C (–321 °F)It can also be guaranteedHigh accuracy and stability. Thanks to its extremely compact design, the device can be installed anywhere, even in tight spaces.LNGmass has no moving parts and requires no maintenance.
The FTM-LNGmass series mass flow meter uses the Coriolis force effect to directly measure the mass flow of the medium passing through the flow meter. On this basis, it is specially designed and developed for LNG filling machines to improve its stability and high accuracy in low temperature environments. It can measure its mass flow, volume flow, density, etc. under harsh working conditions, and is suitable for filling, transportation, storage control, etc. in low temperature environments.
■ Reliable measurements even in extreme environments
■ Integrated process measurement equipment - (flow, density, temperature) multi-variable measurement
■ Save space required for installation - no front and rear straight pipe length requirements
■ Compact structural design: small space to achieve all functions
■ Quick commissioning: preconfigured devices
■ Automatically restore data to facilitate service
■ The Coriolis mass flow measurement principle is not affected by the physical properties of the fluid itself (such as viscosity and density).
■ Precise metering of low-temperature liquefied natural gas in liquefied natural gas (LNG) dispensers.
■ Flow rate up to 18 000 kg/h (660 lb/min)
■ Media temperatures as low as –196 °C (–321 °F)
■ Nominal diameter: DN 8 to 25 (3/8 to 1")
■ Sturdy and wear-resistant compact transmitter housing
■ Modbus RS485
■ Designed to meet application requirements
