Recommended for clean fluids like water, glycol, oil and most chemicals. Portaflow ultrasonic sensors strap-on the outside of vertical or horizontal pipes from 2" to 40" (50 to 1000 mm) diameter. The ultrasonic signal travels through all common metal and plastic pipe materials. Sensors can be mounted without shutting down flow and there is no obstruction or pressure drop. Flow rate and totalizer are displayed continuously along with battery status, signal strength. Press one key to instantly change the units of flow measurement (e.g. from gallons to liters). Real time flow can be displayed in large numeric values or as a graph.
