The KFR line of flowmeters offers the perfect balance between low-cost, accuracy and range availability. Bridging the microflow and large flow ranges, this meter can provide an effective solution to many industrial applications.

The KFR has a one-piece acrylic body with PVC or metal fittings for durability. To take the guesswork out of reading the flow, large lettering and extra hash marks make the scale clearly visible. Further enhancing readability, the low flow meters offer an inherently stable float design, while the larger meters feature a float stabilization mechanism. In the larger flow ranges, the stabilization mechanism allows KFR to offer you a smaller installation footprint and a correspondingly lower price.

To further increase the value of the KFR product line, the low volume flowmeters (models KFR-1000 through KFR-4000) are available with integral needle valves. Accuracy, value, low cost. Three not-somutually- exclusive attributes made possible by the KFR.
