1.1 Introduction
This manual describes the operation of the Greyline Portaflow PT500 portable flowmeter. The flowmeter is
designed to work with 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 PT500 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 5000mm and constructed of almost any material. The instrument will also operate over a wide range of fluid
temperatures.
Easy to operate, the Portaflow PT500 standard features are:
•
Large, easy to read graphic display with backlighting
•
Simple to follow dual function keypad
•
Simple ‘Quick Start’ set up procedure
•
98k stored data points

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 Portaflow PT500 applications include:
•
River water
•
Seawater
•
Potable water
•
Demineralised water
•
Treated water
