Operation Manua Bookl 

The Portaflow 300 brings a new simplicity to the non-invasive measurement of liquid flow. This clamp-on ultrasonic
instrument offers the user quick and accurate flow measurement from outside the pipe.

Micronics engineers have utilised their 15 years experience of developing portable flow measuring instruments to design a
compact rugged and reliable unit. The instrument gives a digital readout of velocity or volumetric flow rate and total integrated
flow in either imperial or metric units. Outputs include an RS232, 4-20mA and pulse that allow the user more versatility when
collecting application data.

The Portaflow 300 is supplied in a waterproof carrying case which houses the electronics, transducer assemblies and all
mounting hardware suitable for most flow applications. A separate carrying case is used when transducer set D is included
within the kit of parts supplied.

The instrument is able to work on a wide variety of pipe sizes from 13mm up to 5000mm, simply by selecting the correct
transducers and attaching them to the outside of the pipewall using the hardware provided. Transducers work up to
200c as standard.

Operation is push button easy such that the user is only required to know the pipe dimensions and the type of pipe wall
material. All other application parameters can be measured by the instrument itself.



The Portaflow 300 is a Transit Time ultrasonic flow meter that has been designed to work with clamp-on transducers, thus
enabling liquid flowing within a closed pipe to be measured accurately, without the need for any mechanical parts to be
inserted through the pipe wall or to protrude into the flow system. When ultrasound is transmitted between transducers X and Y,
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 measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.
Micronics engineers have developed a measurement technique which has the ability to resolve extremely small time differences
down to 25 pico seconds (25x10 -12 seconds), thus giving extremely good performance on small pipes or in large pipes with
low velocity flows.

Flow range

Flow range is dependent on the pipe size and the velocity of the liquid being measured. The 4 transducer sets have been
specifically designed to cover a wide range of pipe sizes and flow ranges. Transducer set C trebles the velocity range of transducer
set B, allowing for higher velocity flow to be measured on larger pipes. Transducers can be used in either Reflex or Diagonal mode
to provide the performance best suited to every application.

Data logger

The built in data logger has a 100K memory which is able to log 50,000 readings. Data can be stored in 5 second to 1 hour intervals.
Each individual site or application can be programmed with the name of your choice, which makes the stored data easily identifiable
when being displayed on the screen or being downloaded. The data for each site is stored in the memory until it has been cleared.
The stored data can be displayed on the instrument in text or graph format. The instrument is also capable of downloading the stored data via the RS232
output port to a printer or PC onto a standard spreadsheet.
