Does severe fluctuation in the E+H flow meter indicate two-phase flow?

This results in large fluctuations in the flow meter’s readings. The flow meter is installed on the ethylene balance line leading to the tank area of the facility; if a gas-liquid two-phase condition exists, how can this situation be eliminated?
? Is it definitely electromagnetic? Haven’t seen two-phase flow in telegraphy ； And I’ve also never seen liquid ethylene being treated with electromagnets.
How long has it been in use? How is the installation location?
What is the temperature at the top of the ethylene distillation tower? What is the temperature of the storage tank? If the local (minimum) ambient temperature is higher than both of the above temperatures, no condensation will form on the balance line.
