Flow meters, placing them in DJB store, Installing and commissioning of the flow meter and accessories. 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 manufacturer's in house volume flow calibration lab should be at least 3 times better than accuracy of the flow meter. Accuracy of manufacturer's 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. 0Separate Transmitter panel, LPU, FIT, MCB, power cable and signal cable of reputed make should also be provided.
