The Model 140MX from Hawk Measurement, Middleton, MA, is an oscillatory flowmeter that uses a specially designed geometric shape to produce self-induced oscillations. The device has no piping run requirements and offers typical accuracy of 1% of flow rate, 0.25% of flow rate repeatability, and 12:1 turndown. The flowmeter works with pipe sizes of 0.75 in., 1.0 in., and 1.5 in. and with fluids with viscosities up to 80 cS.
