1949) How a Cover Meter Works? The change of inductance of an iron cored inductor known as ‘search unit’ due to the proximity of the reinforcing bar is used to measure the ‘cover’. The search unit is moved on the surface of the concrete and rotated till the maximum deflection is seen on the indicator. The meter is calibrated with the concrete block and thereafter the search unit is used to find the position of the reinforcement in structures. (Rao‚ 1949) Importance of Cover Meter in the Industry
