1 INTRODUCTION
1.1 General Description
The Portaflow range of portable flow meters uses clamp-on transducers to enable the flow of a
liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts
through the pipe wall or protrude into the flow system.
Using ultrasonic transit time techniques, the Portaflow is controlled by a micro-processor system
which contains a wide range of data that enables it to be used with pipes with an outside diameter
ranging from 13mm up to 1000mm (depending on model) and constructed of almost any material.
The instrument will also operate over a wide range of fluid temperatures.
All models have the following standard features are:

Large, easy to read graphic display with backlighting.

Simple to follow dual function keypad.
 Simple ‘Quick Start’ set up procedure.

Continuous signal monitoring.

Pulse output (volumetric or frequency).

4-20mA, 0-20mA or 0-16mA output.

Rechargeable battery.

Battery management.

Diagnostics.
Volumetric flow rates are displayed in l/h, l/min, l/sec, gal/min, gal/h, USgals/min, USgals/h, Barrel/h,
Barrel/day, m³/s, m³/min, m³/h. Linear velocity is displayed in metres or feet per second. When
operating in the ‘Flow Reading’ mode the total volumes, both positive and negative, are displayed
up to a maximum 12-digit number.
The flowmeter can be used to measure clean liquids or oils that have less than 3% by volume of
particulate content. Cloudy liquids such as river water and effluent can be measured along with
cleaner liquids such as demineralised water.
Typical applications:

River water.

Seawater.

Potable water.

Demineralised water.

Treated water.
