NIT No. 13 (23-24) Item No. 9

SITC of 300 mm dia. full bore electromagnetic flow meter, working on faradays law of electromagnetic induction and should be having two parts the flow sensor (primary head) and Flow transmitter / converter. The Flow sensor shall have 2 built in sensing electrodes of SS 316. The liner material shall be strictly PTFE or Hard Rubber with drinking water approval from CFTRI. The liner approval should be submitted with the offer. The flow meters should be calibrated at 3 points with water as medium at the manufacturer in house NABL accredited volume flow calibration facility in India. In case the flow meter manufacturer facility is not NABL accredited then flow meter calibration should be compulsory done at FCRI Palakkad only. Operating pressure : Max pressure 10 Kg/cm2 g, Operating temperature: 0 °C to 60 °C max , Fluid: Water, FLOW SENSOR ( PRIMARY HEAD), Type : Pulsed DC excitation, MOC of Flow tube/Meter Tube: SS 304, Lining material : Hard Rubber or PTFE, Measuring Electrode material: SS 316. Meter Flange type & MOC : Fixed Welded Flanges in CS. (Lap joints flanges or Wafer Design not acceptable), Meter Flange Pressure Rating: ANSI 150#, Flow Sensor Coil housing type & MOC: Fully Welded Construction., Material: SS 316, Junction Box MOC: SS 316 or Die Cast Aluminium, Earthing Type. Grounding Ring of SS 316 on both sides of the meter, Ingress Protection: IP 67. FLOW TRANSMITTER (CONVERTER), Type: Microprocessor based, Remote/compact Version, Power supply: Universal…100…230 VAC (-15% / +10%), 50/60 Hz OR 24 VDC suitable for Solar system, Type of display: 2 Line Backlit LCD display, Display parameter: Instantaneous Flow, Sum Totalizer Flow, Forward / Reverse Totalizer, Flow Direction, Status symbols, Measuring accuracy: ±0.5% of the measured value for velocity > 0.5 m/S, Input: From flow Sensor, Outputs: 1 X 4-20mA ( HART), 1 X Pulse,1 X MODBUS RS 485,1 X Status (For Diagnosis),Communication Interface:,1 X MODBUS RS 485, 1 X HART, Application Diagnostic Functions: Empty Pipe Detection, Flow Exceeding Limit, Device/ Hardware Error, Totalizer Overflow, High Electronics Temperature. Enclosure MOC: Die Cast Aluminium, Enclosure protection class: IP 67, Programming: Keypad or Magnetic or Optical, Cable Glands: 4 nos. M20 X 1.5 Polyamide cable glands. The job involves cutting of the road. Installing and commissioning of the flow meter and accessories and rebuilding the road. The flow meter should be IP 68 to stop damage by ingression of water/seepage. Custody and responsibility of the above system will be in customer's scope after commissioning. In case of foreign manufacturers who do not have manufacturing facility in India the Flow meter 3-point water calibration should be compulsory done at FCRI Palakkad only. The accuracy of manufacturers in house volume flow calibration lab should be at least 3 times better than accuracy of the flow meter. Accuracy of manufacturers in house volume flow calibration lab should be mentioned in NABL accreditation and should be less than +/- 0.1%. Testing of meters: Magnetic flow meter manufacturer should carry out the following test on every single flow meter during the manufacturing process and below test certificates should be provided for review during inspection and finally all certificates supplied along with the material: Three Point Water calibration certificate, Hydro test certificate, Material test certificate for Electrode, Coil housing & flow tube, Test and Guarantee Certificate. Separate Transmitter panel, LPU, FIT, MCB should also be provided. Make Forbes (Krohne) Marshall /Siemens /EIP/ Any DJB Approved make
