1. Product description
1.1 General description
PFM Flex 4 (PFM = Pressure Flow Meter) is an instrument for
pressure- and flow measurements. The intended usage is checking-
and documentation of water flow in heating- and cooling constructions.
PFM Flex 4 consists mainly of a Measuring Sensor and a Hand
Terminal (PPC) including the BalanceFlex program software. The
Sensor measures differential pressure as well as temperature and
communicates via Bluetooth with the Hand Terminal.
The Hand Terminal software comprises data of most of the existing
balancing valves on the market. From the Hand terminal list of
Balancing Valves, the operator choose the actual one (manufacture,
model, dimension, position (giving the corresponding KV). This valve
data together with measured DP are the basics for calculation of the
correct flow which will be displayed on the Hand terminal screen.
Measurement readings can be shown in a graphical form in the Hand
Terminal. Readings of balanced values with respective valve data can
be saved and later shown on the Hand Terminal screen or even on a
PC screen that is connected to the Hand Terminal. The Hand Terminal
has a rechargeable battery, type Lithium Ion as well as a system
battery. Charging of Hand Terminal is done via enclosed charger.
The PFM Flex 4 includes more functions than just commissioning
items. Media and Log functions, on-line graphical display of DP,
temperatures and flow. Temperature difference (DT) can be measured
or given manually to on-line graphic display of Power capacity and
Energy amount carried by a particular flow. Flex 4 can be used at heat
pump and solar installations, error tracing, at cooling and air
conditioning systems.
The Sensor has two connections for hoses that are to be connected
over the measuring object. There is also a handle device on the Sensor
for opening and closing of the measuring cell.
The Sensor has a rechargeable battery pack of 6.600 mAh. Charging is
done via the enclosed battery charger.

2. Handling
The instrument PFM Flex 4 is robust
and easy to handle but should not
be exposed to careless usage.
Avoid exposing the instrument to
temperatures below zero degrees C
if there is water in the Sensor.
To empty the Sensor just open the
Sensor valve (by-pass position) and
shake the Sensor.
If the instrument is not being used for
a period, we recommend overhaul
charging of Sensor and Hand
Terminal.

3. Preparations - Measuring
3.1 Measuring Sensor.
Start the Sensor by pressing the
On/Off button. A green led indicates
that the Sensor with its’ computer as
well as Bluetooth transmitter is ”on”.
Bluetooth connection to a Bluetooth
object such as Handterminal is
indicated by the blue led lighting.
Before connecting the Sensor to a
flow system or balancing valve, an
Offset calibration must be performed.
See 3.2.4.2. Page 15.
Connect hoses to the Sensor’s two
pressure ports. Blue to blue and red
to red. Connect measuring needles to
hoses. Connect needles to the
pressure outlets of the measuring
object. Needle with red hose to
pressure outlet with the higher
pressure (often red marked) and
needle with blue hose to the other
(blue marked) outlet. After completed
measurements, the Sensor is put ”off”
by pressing the On/Off button.
If the Sensor by any reason would
jam or if it is not possible to come in
contact with it, the Reset function is to
be used. Push the Reset button to
perform a soft reset.

3.2 Hand Terminal.
Before doing the settings you
must start the Hand Terminal by
pressing the On/Off button on the
upper right of the Pda front. On
the upper left there is a blue light
which indicates the Bluetooth
function of the Hand Terminal.
Close to the right, there is another
lamp which lights red/orange,
when the Hand Terminal is being
charged. Please also see
Technical Data, Power Supply,
Hand Terminal.
The Start Menu of the Hand
Terminal is now visible.
At the upper right corner of the
Hand Terminal there is a terminal
pen. This pen facilitates when
doing menu choices on the
screen.

Preparations – Measuring, cont’d
Tap ”Start” or the MS symbol at the upper left to
scroll down the program list. In the list, you will
find ”BalanceFlex”. Tap ”BalanceFlex” in order to
start the BalanceFlex measuring program. (For
info regarding other programs and functions,
please see the enclosed HP Manual).
When starting the BalanceFlex program, the
program browser automatically starts to search for
objects (Measuring Sensors) with Bluetooth
transmission. Please also see ”Browser”, 3.2.1.2,
page 10.
The main menu of the BalanceFlex measuring
program is now displayed. Se picture to the right.
After a few seconds, short and rising tones are
heard. These tone signals inform that contact is
established between the Sensor and the Hand
Terminal via the Bluetooth function. The contact is
also confirmed when the battery indicator turns
green in accordance with the Sensor’s battery
status, as well as the serial number of the Sensor
is displayed above the battery indicator. (If battery
level is low, the Sensor should be charged; see
Technical data, Power supply, Sensor). The serial
number of the Sensor is also presented on a label
at the back side of the Sensor.
Before choosing Measuring Method (represented
by ”1” resp ”2” below ”Measuring Method”),
Settings,(for example units) could be performed.
