1INTRODUCTION
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.

1.2 How Does It Work?
Portaflow flow meters use a cross correlation transit time algorithm to provide accurate flow
measurements.
An ultrasonic beam of a given frequency is generated by applying a repetitive voltage pulse to the
transducer crystals. This transmission goes first from the downstream (blue) transducer to the
upstream transducer (red) as shown in the upper half of Figure 1. The transmission is then made in
the reverse direction, being sent from the upstream transducer (red) to the downstream transducer
(blue) as shown in the lower half of Figure 1. The speed at which the ultrasound is transmitted
through the liquid is accelerated slightly by the velocity of the liquid through the pipe. The
subsequent time difference T1 –T2 is directly proportional to the liquid flow velocity.
The Portaflow system can be set up to operate in one of four modes determined mainly by the pipe
diameter and the type of transducer set in use. The diagram below illustrates the importance of
applying the correct separation distance between the transducers to obtain the strongest signal.
Reflex Mode
This is the mode most commonly used. The
two transducers (U & D) are attached to the
pipe in line with each other and the signals
passing between them are reflected by the
opposite pipe wall.
The separation distance is calculated by the
instrument in response to entered data
concerning the pipe and fluid characteristics.
Reflex Mode (double bounce)
In this mode the separation distance is
calculated to give a double bounce. This is
most likely to occur if the pipe diameter is so
small that the calculated reflex mode
separation distance would be impractical for
the transducers in use.
Reflex Mode (triple bounce)
This illustration goes one step further to show
a triple bounce situation. This would normally
apply when working with very small pipes
relative to the transducer range in use.
Diagonal mode
This mode might be selected by the
instrument where relatively large pipes are
concerned. In this mode the transducers are
located on opposite sides of the pipe but the
separation distance is still critical in order for
the signals to be received correctly.
This mode might be used with the standard ‘A’
& ‘B’ transducer sets but for really large pipe
installation the optional transducer set ‘D’
might be recommended.

1.5 Display and connectors
The Portaflow unit is microprocessor-controlled, operated through a menu system using an inbuilt
LCD display and keypad. It can display the instantaneous fluid flow rate or velocity, together with
totalised values.
The instrument can also provide a variable current or variable ‘pulse’ (volumetric or frequency)
output that is proportional to the detected flow rate. This output can be calibrated to suit a particular
flow range and used with a range of external interface devices, such as those found in BMS or site
monitoring systems.
Portaflow 333 units can also act as a data logger. When operating in the data logger mode the
logged data can be output directly to a PC or printer using the RS232/USB interface or stored in the
instrument’s non-volatile memory for downloading at a later time. Up to 98k logging events can be
stored internally.

1.6.3 Menus and the menu selection keys
To navigate the Portaflow’s menu system, use the three keys on the right hand side of the keypad:
1. Use the UP & DOWN arrow keys to scroll through a menu list and select a menu item, as
indicated by an arrow-shaped cursor on the left-hand side of the screen.
2. Edit or open the active menu choice by pressing the ENTER key.
3. Use the UP and DOWN arrow keys to cycle through the available options or, for numerical
settings, use the keypad to enter the required value.
4. Press the ENTER key to confirm the new setting.
Some menus have more options than can be shown on the screen at the same time, in which case
the ‘overflowed’ choices can be brought into view by continuing to scroll beyond the lowest visible
item.
Menus generally ‘loop around’ if you scroll beyond the first or last items. Sometimes, this is the
quickest route to find the Exit command to close a menu.
If you select Exit on any menu it usually takes you back up one level in the menu hierarchy, but in
some cases it may go directly to the Read Flow screen.

2INSTALLATION
2.1 Positioning the Transducers
For accurate measurements, the transducers must be installed at a position where the fluid flows
uniformly. Flow profile distortions can result from upstream disturbance such as bends, tees, valves,
pumps and other similar obstructions. To ensure a uniform flow profile, the unit must be mounted
away from any cause of flow disturbance.
As a guide, we suggest this is best achieved by ensuring there is a straight length of pipe upstream
of the transducers of at least 10 times the pipe diameter, and 5 times the pipe diameter on the
downstream side, as shown in Figure x, but this may vary. Flow Measurements can be made on
shorter lengths of straight pipe, but when the transducers are mounted this close to any obstruction
the resulting errors can be unpredictable.
Figure 7 Location of unit
To obtain the most accurate results, the condition of both the liquid and the pipe must be suitable to
allow ultrasound transmission along the predetermined path.

Portaflow 222 & 333 User Manual Micronics
Page 10 Issue 3.1 Feb 20
In many applications, an even flow velocity profile over a full 360° is unattainable due, for example,
to the presence of air turbulence at the top of the flow and also possibly sludge at the bottom of the
pipe. Experience has shown that the most consistently accurate results are achieved when the
sensors are mounted at 45°with respect to the top of the pipe.
IMPORTANT: DO NOT EXPECT TO OBTAIN ACCURATE RESULTS IF THE UNIT IS
POSITIONED CLOSE TO ANY OBSTRUCTION THAT DISTORTS THE UNIFORMITY OF THE
FLOW PROFILE. MICRONICS LTD ACCEPTS NO RESPONSIBILITY OR LIABILITY IF
PRODUCT HAS NOT BEEN INSTALLED IN ACCORDANCE WITH THESE INSTRUCTIONS.
2.2 Attaching the Transducers
Type ‘A’ & ‘B’ transducers connect to adjustable guide rails 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 indicated
by the Portaflow unit.
NOTE: THE USE OF CHAINS TO FIX THE GUIDE RAIL TO THE PIPE CAN BE ELIMINATED ON
STEEL PIPES BY USING THE OPTIONAL MAGNETIC GUIDE RAILS. IN ALL OTHER
RESPECTS THE SETTING UP OF THE SENSORS IS THE SAME AS FOR STANDARD GUIDE
RAILS.
2.2.1 Cleaning the contact area
Prepare the pipe by degreasing it and removing any loose material or flaking paint in order to obtain
the best possible surface. A smooth contact between pipe surface and the face of the sensors is an
important factor in achieving a good ultrasound signal strength and therefore maximum accuracy.
2.2.2 Assembling the guide rails on the separation bar
1. Slide the separation bar (D) into the front of the left hand guide rail, align the front edge of the
guide rail with ‘0’ on the ruler scale (E) and secure it in place by tightening the thumbscrew (C).
2. Slide the other end of the separation bar into the front of the right hand guide rail, align the front
edge of the guide rail to the required separation distance (obtained from the Portaflow unit) on
the ruler (F), then secure it in place by tightening the thumbscrew.
NOTE: IF MAGNETIC GUIDE RAILS ARE USED ON STEEL PIPES THEN ONLY THE
LOCATION AT 45° ON THE PIPE APPLY ON THE NEXT TWO SECTIONS.
2.2.3 Fixing the guide rail assembly to the pipe
1. 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.
2. Rotate the complete guide rail assembly so that it is approximately 45° with respect to the top of
the pipe. Then tighten the chain by turning the tensioning thumb-wheel (A) on each guide block
until the assembly is securely attached to the pipe.
NOTE: IF YOU ARE UNABLE TO GET SUFFICIENT TENSION ON THE CHAIN TO HOLD THE
ASSEMBLY IN PLACE, FULLY SLACKEN THE TENSIONING THUMB-WHEEL AND SHORTEN

2.2.4 Fitting the transducers
1. Slide the transducer cover plate (A) fully towards the outside of the guide assembly to allow
sufficient access to fit the transducer.
2. Clean the face of the transducer, removing all traces of dirt and grease.
3. Apply a 3mm bead of ultrasonic couplant along the centre length of the transducer (E).
Figure 9 Applying ultrasonic couplant
4. Fit the transducer into the guide block –ensuring the lugs on the sides of the transducer are
correctly located into the slots on the sides of the guide block.
5. Slide the transducer cover plate over the top of the transducer and tighten the thumbscrew
finger-tight to secure the transducer in place. When securing the cover plate take care to leave
sufficient room around the transducer connector to connect the cable.

2.3 Connecting Temperature Probes (Portaflow 333 only)
The temperature sensors must be located at the input and output of the system that is being
monitored. The area of pipe where they are to be attached must be free of grease and any
insulating material. It is recommended that any coating on the pipe is removed so that the sensor
has the best possible thermal contact with the pipe.

2.4 Connecting Outputs
The output cable provides a 4-20mA current source that can drive a maximum load of 620Ω and 3
digital output pairs for pulse or alarm outputs.
The isolated pulse output is provided by a SPNO/SPNC MOSFET relay which has a maximum load
current of 500mA and maximum load voltage of 24V AC/DC.
This output is suitable for SELV circuits only.
The pulse output is a Volt, or potential free contact and, when selected as a low flow alarm, is
configurable NO/NC.
The 4-20mA current output is available on the white (high polarity) and black (low polarity) wire pairs
(pins 1&2 on the connector). The alarm current due to a flow outside the range specified or due to a
loss of signal is set at 2.5mA.
Using the instrument’s menu system (see page 34), you can:
Select the current output function Off/On
Select the current output signal range (4-20mA, 0-20mA, 0-16mA)
Calibrate the current output signal to a required flow range

2.5 Connecting the Power Supply
Operating power is provided by an internal battery that can be charged from the utility supply using
the supplied external charger. When you first receive the unit you must put the battery on charge for
a minimum of 6.5hrs before use. A fully charged battery will power the instrument for up to 20hrs
depending on the output utilisation and backlight usage.
2.5.1 Charging the battery
1. Connect the external battery charger to the charger socket at the bottom of the instrument then
switch on the utility supply.
2. When switched on, the instrument indicates charging with an animated battery symbol to the
left of the date.
3. Leave the instrument on charge for at least 6.5 hours before using it for the first time.
2.5.2 Optimising battery life
The backlight can be configured in the Setup Instrument menu (see page 18) to be either
permanently OFF, timed to switch off after 5-120s of keypad inactivity, or permanently ON. If the
backlight is active continuously it will reduce the available battery operating time to 8 hrs. Similarly, if
the 4-20mA output is used constantly at 20mA, the battery life would reduce by 50%. It is therefore
beneficial to turn off the backlight and 4-20mA output facilities when they are not required.
When the instrument is operating in the Flow Reading mode the percentage battery charge level is
displayed symbolically on the LCD screen. A warning message is triggered if the charge falls to
approximately 30%, at which point there is up to four hours of battery operation remaining,
depending on usage. The battery can be charged both while the instrument is in use or when
switched off. The instrument’s internal data is stored in non-volatile memory and will not be lost
even if the battery discharges completely.
THE BATTERY IS NOT A USER-CHANGEABLE ITEM. THE INSTRUMENT MUST BE
RETURNED TO YOUR DISTRIBUTOR IF THE BATTERY NEEDS REPLACING.
ONLY USE THE SUPPLIED CHARGER, OR SPECIAL ADAPTOR LEAD. FAILURE TO
COMPLY WITH THIS WILL INVALIDATE YOUR WARRANTY.
