Page 5: 1: General Description
1: General Description 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. -
Page 6: Principles Of Operation
The Portaflow PT500 system employs two ultrasonic transducers attached to the pipe carrying the liquid and compares the time taken to transmit an ultrasound signal in each direction. If the sound characteristics of the fluid are known, the Portaflow microprocessor can use the results of the transit time calculations to compute the fluid flow velocity. -

Supplied as standard for use on pipes 1.97” to 78.74” (50mm to 2000mm) outside diameter. Transducer set 'D' Type 'D' transducers are optional equipment that can be used by the Portaflow PT500 on pipes from 59” to 196” (1500mm to 5000mm). They are supplied complete with ratchet straps for ‘diagonal mode’ attachment. -
Page 11: 2: Installation
Installation Transducer Positioning In many applications an even flow velocity profile over The Portaflow equipment expects a uniform flow profile as a a full 360° is unattainable due, for example, to the distorted flow will produce unpredictable measurement presence of air turbulence at the top of the flow and errors. -
Page 12: Transducer Attachment (Type 'A' & 'B')
Transducer Attachment (Type ‘A’ & ‘B’) Type ‘A’ & ‘B’ transducers are fitted to adjustable guide rails which are secured to the pipe using wrap-around chains and mechanically connected together by a steel separation bar. The separation bar also acts as a ruler to allow the distance between the transducers to be accurately set to the value determined by the Portaflow instrument. -
Page 13: Fitting The Transducers
On each guide rail, attach one end of a securing chain to a hook on the tensioning bar (B), wrap the chain around the pipe (G) and then attach it to the hook on the other end of the tensioning bar whilst keeping the chain as tight as possible. -

3.1.1 Using the instrument for the first time Before you use your Portaflow PT500 for the first time you should first charge the battery, then select the display language and set-up the internal clock, as described below. Charging the battery Connect the external battery charger to the charger socket at the bottom of the instrument then switch on the utility supply. -
Page 17: Enabling/Disabling The Backlight
If the point at which you intend to take the measurement is likely to require regular monitoring it is best to set it up as a ‘Site’ within the Portaflow PT500, which then stores the site parameters (See Managing Named Sites). - Page 18 Before you can use the Portaflow system you need to obtain the following details (this information will be required when setting up the Quick Start menu): • The pipe outside diameter • The pipe wall thickness and material • The pipe lining thickness and material •...

Page 24: Instrument Calibration
Instrument Calibration The Portaflow is fully calibrated before it leaves the factory; however the following adjustments are provided to allow you to further ‘fine tune’ your instrument to suit local conditions and application where necessary. Apart from the zero flow offset adjustment, these are normally carried out only where the instrument is to be used in a permanent or semi-permanent location. -
Page 25: Adjusting The Calibration Factor
Key Point: In order to cancel any applied offset you must either read flow via Quick Start or switch the Portaflow instrument OFF & ON. Any value that you trim-out using the offset adjustment will be added/subtracted from the flow reading across the whole range. - Page 26 Pipe Material Roughness Factor Non ferrous metal 0.01 Glass Plastics Light metal Drawn steel pipes: 0.01 •Fine planed, polished surface •Plane surface •Rough planed surface Welded steel pipes, new: •Long usage, cleaned •Lightly and evenly rusted •Heavily encrusted Cast iron pipes: •Bitumen lining •New, without lining •Rusted / Encrusted...

Page 28: Performing Monitoring & Logging Functions
Performing Monitoring & Logging Functions 3.6.1 How to measure totalised flows (manually) The basic measurement indicated on the FLOW READING screen is the instantaneous flow rate, which in some applications may vary over a period of time. Average flow rates are therefore often required in order to get a better understanding of an application’s true performance. - Page 29 Calculating the average flow To calculate the average flow wait for the allotted monitoring period to expire then divide the indicated total flow by the time taken. This will give you the average flow in m/s, galls/hours or whatever units you select. Note that in a bi-directional flow situation you must calculate the difference between the indicated positive and negative flow totals before carrying out the average flow rate calculation.

Page 47: Warning & Status Messages
Warning & Status Messages FLOW RATE ERRORS No flow signal Interpretation: This message appears when the transducers cannot send or receive signals to each other. Response: Firstly check that all cables are connected, transducers are on the pipe correctly with sufficient couplant on the face. This condition could also be due to a partially empty pipe, aerated liquid, particulate content too high or when the condition of the pipe being measured is poor. - Page 48 BT Module Not Found! Interpretation: No response from the internal Bluetooth Module. Response: Try again. If still no response contact Greyline Instruments. Failed to connect to printer! Interpretation: The unit has failed to make connection with the default Bluetooth printer.
- Page 49 BATTERY ERRORS Battery Low Interpretation: The battery has discharged to below 30% remaining. This leaves the instrument with approximately 4 hours remaining, depending on power usage, before it needs recharging. Response: Recharge the internal battery at the earliest opportunity. Do not leave the instrument for a prolonged period with a fully discharged battery.
