Question

Which of the following electrode/s are used in the silo?

(a) High Level Electrode

(b) Low Level Electrode

(c) High Level Electrode and Low Level Electrode

(d) Medium Level Electrode

The question was posed to me in an interview.

My query is from Storage in section Collection and Reception of Milk of Dairy Engineering

Answer 1

Right option is (c) High Level Electrode and Low Level Electrode

To elaborate: An electrode is often fitted in the tank wall at the level required for starting the agitator. The agitator stops if the level in the tank drops below the electrode. This electrode is known as the low-level indicator (LL). A high-level electrode (HL) is fitted at the top of the tank to prevent overfilling.
