Providing, Supplying, Installing, Testing and Commissioning (SITC) of Ultrasonic Open Channel Flow Meter Kit and its accessories at 30MLD STP site Location in Hukumpeta area in RMC.

Providing, Supplying, Installing, Testing and Commissioning (SITC) of Ultrasonic Open Channel Flow Meter Kit suitable for continuous monitoring of flow in open gravity sewage/storm water channels up to 30 MLD capacity, complete with non-contact ultrasonic level sensor having IP68 protection, corrosion-resistant housing, measuring range suitable for channel depth, accuracy ±0.25% or better, and integrated temperature compensation. The system shall include a microprocessor-based flow transmitter with preloaded calibration curves for standard Parshall Flumes, Venturi Flumes and V-Notch/Rectangular Weirs, local dual-line backlit LCD display indicating level, instantaneous flow, totalized flow and diagnostics. The transmitter shall support 4-20 mA analog output, RS-485 Modbus communication, programmable relays, data logging, password protection, surge protection and weatherproof enclosure. The item shall include mounting brackets, sensor cable, cable glands, power supply arrangement, calibration, commissioning, testing, documentation and all accessories required for complete operation as directed by the Engineer-in-Charge.

Providing, Supplying, Installing, Testing and Commissioning of Complete V-Notch Flow Measurement System comprising SS-304 sharp-crested V-Notch Weir, non-contact ultrasonic level sensor (IP68), flow transmitter with pre-programmed V-Notch discharge equations, local LCD display, 4-20 mA output, RS-485 Modbus communication, mounting arrangements, calibration and commissioning complete for continuous flow monitoring applications

Providing, Supplying, Installing, Testing and Commissioning (SITC) of Integrated Industrial GPRS/GSM Telemetry RTU suitable for remote monitoring and transmission of flow, level and equipment status data from field installations to Municipal Central Monitoring Server. The RTU shall be microprocessor-based, industrial grade, with inbuilt Quad-Band GSM/GPRS/4G communication modem and SIM card interface, capable of transmitting real-time data packets using MQTT, HTTP/HTTPS, TCP/IP and JSON protocols. The unit shall support minimum 4 Analog Inputs (4-20 mA), 4 Digital Inputs, 2 Relay Outputs, RS-485 Modbus RTU communication and onboard memory for data logging during communication failure. The RTU shall be provided with industrial power supply, surge protection, watchdog timer, configurable reporting intervals, remote firmware upgrade capability, and local diagnostic LEDs. The system shall include a high-gain outdoor external antenna, antenna cable, mounting hardware, weatherproof IP65 enclosure, configuration software, integration with Municipal SCADA/Cloud Server, testing, commissioning, documentation and all accessories required for complete and satisfactory operation as directed by the Engineer-in-Charge.

Providing, Supplying, Installing, Testing and Commissioning (SITC) of Internal Data Logger Storage Module for telemetry-based flow monitoring systems, comprising high-capacity industrial-grade non-volatile flash memory for local storage of time stamped flow, level, alarm and system diagnostic data. The module shall support automatic data logging during GSM/GPRS/4G communication outages and seamless synchronization of stored records to the central server upon restoration of network connectivity. The memory capacity shall be sufficient to store a minimum of 100,000 records or 12 months of historical data, whichever is higher. The module shall provide secure data retention without power, error-checking mechanisms, overwrite protection, configurable logging intervals, event-based recording, and compatibility with MQTT/HTTP/JSON telemetry systems. The item shall include firmware integration, configuration, testing, commissioning and all accessories required for complete operation as directed by the Engineer-in-Charge

Providing, Supplying, Installing, Testing and Commissioning (SITC) of IP65 Outdoor Weatherproof Enclosure Panel made of heavy-duty UV-resistant polycarbonate or powder-coated mild steel construction, suitable for outdoor wall/pole-mounted applications. The enclosure shall be IP65-rated for protection against dust and water ingress and shall be provided with lockable latches, hinged door, mounting brackets, cable glands, DIN rails, internal wiring channels and ventilation arrangements. The panel shall be designed to accommodate and securely house the telemetry controller/RTU, GSM/GPRS/4G telemetry card, battery bank, power supply unit, surge protection devices, terminal blocks, MCBs, internal fuses and associated accessories. The item shall include all mounting hardware, internal interconnections, earthing arrangements, anti-corrosion treatment, testing, commissioning and all incidental works required for complete and satisfactory operation as directed by the Engineer-in-Charge.
