Introduction
PFM 1000 Instrument
Features
The PFM 1000 instrument is designed for hydraulic balancing of heating and cooling systems. It allows
measuring static pressure, differential pressures and flow in the said systems. Using the differential
pressure measured by the measuring component in the system, PFM 1000 calculates the flow that
runs through the component (balancing valve or measuring orifice). The application corrects the
calculated flow also for anti-freeze mixes in cooling systems. The flow can be measured in all branches
of the whole hydraulic system and the whole system can be balanced.
The core of the instrument consists of the pressure measuring unit that measures pressure in
balancing components of hydronic systems and sends the measured values to the Bluetooth Low
Energy (hereinafter just BLE) technology in a mobile device with the Android or iOS operating
systems. The PFM 1000 measuring unit is very robust with a massive heavy-duty frame that can
withstand a fall from 2 meters. Inside the measuring unit, there is a hydraulic section with a builtin symmetrical differential sensor for accurate digital processing of measured data. The PFM 1000
measuring instrument is very accurate and this accuracy is based on:
• Very accurate measuring of the pressure with a fully differential pressure sensor and 24-bit
processing of data from the pressure sensor
• Possibility of resetting the differential pressure for pressure measuring of very low differential
pressures. The resetting of measuring is done at the hydraulic bypass of pressure inputs.
The PFM 1000 instrument uses advanced digital technologies that compensate inaccuracies usually
occurring in pressure measuring, such as temperature dependencies and measuring non-linearity.
Another feature of the PFM 1000 instrument consists in recording measurements. Data from
measuring can be recorded independently and directly in the pressure measuring unit. The
measuring unit is equipped with a time circuit that allows programming a periodical recording of
measurement independently on the application in the mobile device. Once the recording is complete,
the measuring unit turns off and the record remains stored in the measuring unit until the application
reads it out. Another method of recording consists in recording of current values directly into the
mobile device.
Using the BLE transmission, the PFM 1000 application communicates with the measuring unit; a
user-friendly interface can be handled via the user mobile device. The application processes pressure
values and allows displaying the flows in the measured system based on features of balancing
components stored in the mobile device’s storage. The application stores in the mobile device’s
storage balancing valves of most leading European producers. If, incidentally, a valve in not contained
in the application, you can enter the valve’s Kv and the application will calculate the flow from this
value.
You can handle the software by direct touching required fields, or you can use the menu in the upper
section of the screen.

this item remains empty. When you will be measuring with the automatic connection of one unit
without searching and you will want to connect another pressure unit, you must delete this field.
Once the Battery type is selected, enter the used AAA battery type in the pressure unit. This setup is
very important for the correct calculation a display of the battery condition indication. You can find

Pressure Unit Turn-on
Measuring
When switched on, the instrument initialises itself. This take several seconds and the
green light indicator on the instrument is flashing quickly period 200ms during the
initialisation. Do not establish the Bluetooth connection with the measuring instrument
until this light indicator stops flashing and is on steadily. If the green light indicator fleshes
with 1 second period, there is an error in the BLE module initialisation. Try to switch off the
instrument, wait for several seconds and turn it on again.
Once the Measuring button is selected, a window is displayed on the introductory screen for
searching and connecting with the measuring unit. After the Scan button is pressed, the PFM 1000
application will search for and display available PFM 1000 devices. Select your PFM 1000 unit from
the displayed list using the last four digits of the serial number and confirm the option by pressing
the Connect button. This function occurs in many other places in the PFM 1000 application. If you
check the Always use the selected device option, the PFM 1000 application will connect with this unit
automatically and will not search for any other. Once the Measuring button is pressed, the Measuring
screen will appear straight away.
You can cancel the Always use the selected device from the Application Setup, the Sensor Preferences /
Always use Bluetooth Address option. Here, delete the Bluetooth address of your pressure unit module.
Measuring Window
Based on the differential pressure measured, type of measured medium, its temperature, valve and
its preset, the application displays the differential pressure in measuring points of the attached fitting
and compute the flow through this fitting.
The status line in the screen’s bottom displays several important pieces of information:
1. The last four digits of the serial number of the pressure unit connected.
2. The percentage status of the battery of the pressure unit connected.
3. The validity of calibration of the pressure unit connected.
4. The firmware version of the pressure unit connected.
You can find settings available in the Measuring window in the context menu after pressing a button.
You can find the button in the upper right corner of the screen.

Select Valve
You can select the required valve by pressing the Select valve selection list.
After clicking on the blue Manufacturer line, the list of valve manufacturers contained in the PFM 1000
instrument database will open from which you select the manufacturer required by you. The database
of valves in the instrument contains valves the world’s leading manufacturers. When selecting the
valve and its preset, the Kv values provided by the manufacturer will be used for the flow calculation.
The Kv values are recalculated by the mathematical function from manufacturers’ tables.
After clicking on the blue Se lect Type line, the list of valves of the given manufacturer will open from
which you can select the required valve type. For simpler orientation and selection, also the photo for
each valve type will be displayed for you.
Valve Preset
You can change the valve preset from the Change presetting selection list.
For every valve, the preset field displays the interval in which you can enter the preset.
Medium
You can select the heat-transfer medium of the measured system by pressing the Select Medium
selection list.
If you select as the medium the Ethylenglycol or Propylenglycol ant-freeze mix, you will have to
enter the given anti-freeze mix concentration in the Concentration field. Then, the application will
recalculate the flow calculation using this value. Also, you can find under the Concentration field data
on the extent in which the concentration can be specified and entered.
Kv Direct Setup
In case the database of valves does not contain the valve you require you can measure the flow using
the Kv direct specification.
You can obtain the table with preset values and Kv values from the documentation of the respective
valve manufacturer.
