Accurate Flow Measurement from Outside a Pipe

The PT400 Ultrasonic Flowmeter is designed for clean fluids like water, glycol, oil and most chemicals. Sensors can be mounted without shutting down flow and there is no obstruction or pressure drop. The ultrasonic signal travels through all common metal and plastic pipe materials. 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 rate can be displayed on the large LCD display as numeric values or as a graph.

The Portaflow PT400 ultrasonic sensors clamp on the outside of vertical or horizontal pipes. Select a Sensor pair for the range of pipe sizes you will monitor:

'A' Transducers for 0.51" to 4.5" Outside Diameter (13 to 115 mm)*
or
'B' Transducers for 2" to 39.37" Outside Diameter (50 to 1000 mm)*
