Clamp-on Flow Meter - Hire from £50 per day.
Non-Invasive Measurement of Liquid Flow
Bringing simplicity to the non-invasive measurement of liquid flow. Offering the user quick and accurate flow measurement with its easy to follow menu and simple set up. Results can be achieved within minutes of opening the case!
Compact, rugged and reliable, the Portaflow range has been designed to provide sustained performance in industrial environments.
How it works:
This transit time ultrasonic flow meter is designed to work with clamp-on
transducers, providing accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!
When ultrasound is transmitted between the transducers, the speed at which the sound travels through the liquid is accelerated slightly by the velocity of the liquid through the pipe. When ultrasound is transmitted in the opposite direction, the flow of the liquid causes the transmitted sound to decelerate. The subsequent time difference is directly proportional to the flow velocity in the pipe. Having measure the flow velocity and knowing th pipe cross-sectional area, the volumetric flow can be easily calculated.
