Installation/testing/commissioning charges after disconnecting their connections etc. so as not to damage the civil structure. Drilling the water tank, if required, for insertion of capacitance sensor, fixing it securely with fasteners fixing the new controller at site as per requirement and making the wiring the signal and power connections along with complete thimbling/tapping etc. as per the site requirement. Complete laying, checking and connecting the wiring connections, checking and tightening the loose ends of connections, replacing any defected nut bolts and insulators etc., as per site requirement, fixing the MS canopy. Programming of requisite software for energizing the sensor and controller. Ttesting& commissioning the entire system after completing the above work first at passive mode and then repeating the steps in active mode.
