Flow measurement of ethylene
Flow measurement of ethylene gas, as well as ethylene-comonomer gas mixtures under high pressure
High-pressure ethylene and comonomer gas flow measurement
In the world of high-pressure ethylene chemistry, plant operators face many challenges when using conventional flow measuring technologies. A solution is needed that not only enhances process control but also enables predictive maintenance, effectively reducing downtime. Being able to ensure precise flow measurement of ethylene gas and ethylene-comonomer gas mixtures under extreme pressures is absolutely essential, as is the ability to completely avoid any risk of leakage.

The Flexim FLUXUS G608 CA Energy is a portable ultrasonic flow meter and is ideal for carrying out complete energy efficiency tasks (e.g. according to DIN ISO 50001 standards) within hazardous areas (ATEX Zone 1/2 and FM Class I, Div.2 approval) by allowing the measurement of compressed air flow rates as well as the monitoring of thermal energy quantities and the flow rate determination of any kind of liquid or gaseous media with just one device. It is engineered to survey whole compressed air infrastructures, balancing the facilities, measuring on nearly every individual leg, determining the efficiency of compressors and last, but not least, to quantify and localize leaks.
- non-intrusive measurement for precise bi-directional, highly dynamic compressed air, gas, liquid and thermal energy flow rates
- Ideal for inner pipe diameters ranging from DN6 to DN2100 (DN6000 for liquids) and pressures from 43.5 PSI upwards (on plastic pipes at atmospheric pressure and below)
- Portable, easy-to-use flow transmitter with 2 flow channels, multiple inputs/outputs and an integrated data logger with a serial interface
