Magnetic flowmeters are generally not used for the velocity/flow measurement of hydrocarbons due to their ?
Correct answer: B. Low electrical conductivity
- A. Low thermal conductivity
- B. Low electrical conductivity
- C. High viscosity index
- D. Low flash point
Explanation
Magnetic flowmeters operate by inducing a voltage in a moving electrically conductive fluid. Most hydrocarbons have very low electrical conductivity, so they cannot generate a usable measurement signal.
