Level Measurement – Electrical Devices
Measuring and detecting the level of liquids and solids with electrical devices. Single-point level devices, such as ball floats, diaphragms, and rotating paddles that activate electrical switches; continuous liquid level measurement with a float-actuated cable rotating a multiple-turn potentiometer; donut float containing magnets actuating
follower magnet on cable; level detection with conductivity electrodes; and level detection with a vibrating paddle actuated by a solenoid.
Prerequisites: Working knowledge of electricity and familiarity with sight and float instruments.
