Tubing kits are offered to integrate VPFlowScope In-line sensors more easily and to assure accuracy. The tubes are made of stainless steel. The tubing kits for the 0.5 inch and 1 inch have respective lengths of 20x diameters before and 5x diameters after the flow sensor. For the 2 inch, due to weight, the tube has 15x diameters before and 5x diameters after the flow sensor. We offer tubing kits in BSP and NPT thread styles.
