Electrical Maintenance Fund of 14 Dwarka Greens, A Multistoried Composite Houses comprising of 1640 Dus 316 Dus 1 BHK 316 Dus 2 BHK and 1008 EWS) situated at Pocket-5, Sector-14, Dwarka, Ph-II

Wireless Water Level Controller Unit: Supplying, Installation, Testing & Commissioning of 230V AC operated Wireless Water Level Controller Unit with water level indicator by 7 Segment LED display (56mm height) to indicate water level of single/ multiple Overhead or Underground tanks (Maximum 6 Tanks) in percentage with 1% esolution. It will receive water level data wirelessly from Level Transmitters and operate motor (Single/ Dual) accordingly to the set configurations. It will also indicate the flow status, motorized valve status and Audio/ Visual alarm for Overflow alert. Full, Low and Overflow limits for each tank is configurable independently. It will have modbus output for BMS system/ GSM Gateway/ other devices. It consists multiple safety features like high/ low voltage, dry run protection, max run time, minimum number of valves to operate, pipe line pressure etc. It also consists timer based operational features.

Supply, installation, testing & commissioning of 5V DC operated microcontroller based control module to operate multiple motors/ priming pumps/ motorized valves (Maximum 4 Nos in total) in pre-determined sequence. It will have 230V 10amp potential free relay (8 Nos) to operate motors as per desired configurations. It will have capability to configure the settings through wifi. It will also have start and stop button to operate the sequential operation. It can also receive command from external controller to operate the sequential operation in pre-determined sequence. Duration of motorized valve & priming pumps should be configurable independently to assist priming of main pumps. It should also have lock of motor operation which can be access through wifi.

Wireless Water Level Data Transmitter for Overhead tank: Supply, Installation, Testing & Commissioning of ultra-low power inbuilt battery operated water level data transmitter (IP68) with capacitive type water level sensors to measure water level with 1% resolution and flow status and transmit the data wirelessly to controller cum receiver unit. It will have auto calibration sensor for full level and input for motorized valve status and conductive flow sensor to communicate it wirelessly to controller

Wireless Water Level Data Transmitter for Underground tank: Supply,Installation, Testing & Commissioning of ultra-low power inbuilt battery operated water level data transmitter (IP68) with capacitive type water level sensors to measure water level with 1% resolution and flow status and transmit the data wirelessly to controller cum receiver unit. It will have auto calibration sensor for full level and input for motorized valve status and conductive flow sensor to communicate it wirelessly to controller

Wireless Data Repeater: Supply, Installation, Testing & Commissioning of 230V AC operated Wireless signal/ Data Repeater for re-transimitting the wireless data signal of transmitters/ other repeters to further distance to enhance the range. It will have LED Display for indication of Signal strength of recieved signals. It can be configured to recieve the signals of perticular transmitters ID/ Repeatrs.

Motorized Valve: Supply, installation, testing & commissioning of Motorized Valve of ON/OFF Type 230V Single Phase operated Electrical Actuator with aluminium body (IP 67 - weather proof) with limit switch and feedback switch for valve status. It consists a connected Butterfly Valve (working pressure 6Kg/cm.sq.) with SS304/ CI Disc and CI Butterfly Valve Body with Wafer type End Connections. It includes cutting of existing pipe line, fixing/ welding flange of suitable material and size and fixing with suitable size nut bolts with gasket but it excludes any excavation work, dismentling of CC/ RCC work, any civil work, power supply wiring etc. Size: 65mm dia Nominal bore
