The Portaflow 204 Transit Time, clamp-on ultrasonic flow meter has been designed to help Service/Maintenance and commissioning Engineers make quick, accurate flow readings of any liquid, with pipes from 13mm to 115mm NB.

This compact rugged instrument gives a readout of velocity or volumetric flow rate and a total flow in litres and gallons. There is no shut down time, lost production or contact with process liquid when making the measurement, as the instrument is completely non-invasive.

Simple to set up, the Portaflow 204plus is able to measure flow from 0.02 metres/sec up to 8 metres/sec. It is able to measure flow on almost any clear liquids such as water, oils and chemicals, in any pipe material over temperature range of -20°C to +125°C.

Set up is menu driven with the user entering the pipe dimensions, material and temperature. When measuring liquids other than water, speed of sound data must be entered. Programming the instrument and mounting the transducers using the hardware provided, can be completed in under 2 minutes, with stable flow data becoming available immediately.

The unit powered by mains (110/240V) or the internal Ni-Cad rechargeable battery pack, giving an operating life of 8 hours. Thoroughly reliable with a rapid response time of one or two seconds, the Portaflow 204 is an unbeatable instrument for fast and accurate flow measurements.
