These rotameters have a wide range of capacities and tube sizes. Metering accuracy is 2% of full scale (1% with custom calibration) over a 10:1 range. Beaded-guide tubes are available with 5- or 10-inch scales. End fittings for vertical and horizontal connections come in both threaded and flanged types. Choice of such wetted parts materials as brass, carbon steel, 316 stainless, PVC, TFE, Kynar ® , Buna-N, Viton ® , and EPR give a good balance between cost and maximum corrosion resistance. |
