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.

Pressure Measuring Zero, Deaeration of Measuring Hoses
For measuring low differential pressures (under 500 Pa), it is necessary to reset the pressure measuring
of the measuring unit.
The reset function will be activated from the Sensor zero setting selection list. You will be led
through the reset procedure by gradually emerging pictures. By rotating the pressure reset knob to
the left, the pressure inlets are hydraulically connected and physically there is zero pressure difference
between them. In the pressure measuring unit, the zero pressure value is set. Then, turn the reset
button to its default position.
The connection of the pressure inlets can also be used to bleed the connection hoses of the
measuring unit. For media temperatures above
50 ° C, venting of less than 10 seconds is recommended to avoid unnecessary heating of the pressure
unit measuring circuits.

Heating Engineering
Calculations
Heating engineering calculations allow and make easier solutions of partial tasks and calculations in
balancing hydraulic systems.
There are the following four calculations in the PFM 1000 application:
1. Preset calculation - calculates the valve preset for the flow requested in the current branch.
2. Pressure loss calculation - calculates the pressure loss on the valve for the requested flow and
preset.
3. Available pressure calculation - The “available pressure” is understood to be the minimum pressure
in the branch after the requested flow is attained for the given preset.
4. Valve authority calculation - The valve authority is the ratio between the pressure drop on the
fully opened control valve and the pressure in the whole branch in percent. This quantity helps in
dimensioning the valve and evaluating whether the given valve is suitable for the branch. For the
optimal use of the system regulation, this should be in the range of 50 up to 100%. When this value is
less than 50%, the valve is not dimensioned properly.
Press the Calculations in the application’s main menu. Select the requested valve and its preset in the
respective selection fields of the Calculations introductory screen.
Preset Calculation
It calculates the valve preset in the current branch for the requested flow.
Enter the requested flow in the first Preset calculation screen and confirm the entry with the OK
button. Confirm with the actual flow with Save current measured flow button in the next screen.
Close fully the control valve in the next screen. Confirm the measured pressure value with the Save
current disposal pressure button. Based on the measured values and the requested flow, the PFM
1000 application calculates the needed valve preset and displays the result in the Calculations
window in the Results section of the screen.
