Introduction
PFM 5000 Standard has been designed to create hydraulic
balance in heating and cooling systems.It enables measuring of pressure flow and temperatures in a system. Using
differences in pressure, PFM 5000 is capable of turning
these two pressures on both sides of a valve into flow.Flow
through individual branches of the system can be measured, creating perfect balance in the whole system.
PFM 5000 Standard has a number of key features, that
makes it easy to use.
PFM 5000 Standard consists of two separate units: a main
pressure unit for measuring pressure, flow and temperature, and a computing unit for displaying results and data
analysis.
The main pressure unit is extremely robust, with a sturdy
frame and sound cover.Inside the pressure unit is a
differential pressure meter with an integrated true
differential pressure sensor for accurate digital data
processing.
The flow meter automatically corrects the flow for different
types of mediums being measured, such as antifreeze additives in cooling systems.
PFM 5000 Standard has the advantage of high class digital
technology, which enables it to compensate for inaccuracies,
normally associated with pressure measurements, such as
temperature dependency and non-linearity.In order to increase the accuracy of low pressure measuring and to enable
pressure connection deaeration, the main pressure unit is designed with incoming by-pass couplers for hydraulic zero setting.
This forms the basis for the accuracy of measurements.
The PFM 5000 Standard can be supplemented with an external thermometer connected via a coaxial connector.The
temperature of the working medium can easily be measured
by inserting the thermometer into the measuring nipples of
the valve, were you normally insert 3 mm measuring needles.
Specifications for other valve manufacturers than Danfoss are
pre-programmed in the memory of the PFM 5000 Standard.
The autonomous measuring mode of PFM 5000 Standard
allows independent data recording based on a preprogrammed period.The acquired data are initially saved in

PFM 5000 Standard can calculate complicated multi-branch
heating systems by simulating the hydraulic system with
balancing calculations based on two measuring in each
branch.
During balancing calculations, the PFM 5000 Standard
utilises a sophisticated method for calculating hydraulic
resistances within the system. As a result, the PFM 5000
Standard comes up with a proposal with the lowest energy
loss.This function dramatically decreases the time required
for balancing.

Working with projects
PFM 5000 Standard includes a built-in module for project
balancing calculations comprised of one horizontal and a
maximum of 100 vertical branches. The calculation assumes
that the pressure input of
the project is constant and that the project is devoid of
negative feedback hydraulic elements (for instance
differential pressure regulators within branches or
thermostatic valves).

Preparing for project balancing – measuring
1. Prior to measuring, the Initial presetting has to be set on
all balancing valves within the project including the common
valve. When re-balancing an existing or newly designed
project, it is most effective to enter the actual presetting of
balancing valves within.
2. Connect PFM 5000
Standard sensor to the
Project input pressure.

4. Connect PFM 5000
Standard sensor to the
balancing valve at any
branch and select the
appropriate branch in the
Branch tab. It is necessary
to measure both the Flow
through the valve with
Initial presetting of the
balancing valve and the
Available pressure in the
branch with the balancing
valve being closed. The
value measured will be
automatically filled in the
corresponding field.
5. Measuring of disposal
pressure. Close the balancing
valve in the branch prior to
measuring the available
pressure in the branch. The
value measured will again be
saved along with branch
data.
6. Measuring of initial flow

3. In order to minimize power losses in the project, PFM
5000 Standard starts balancing with a 3kPa pressure drop
on the balancing valve in the last branch. Next, the nonbalanced branches are optimized. If for any branch a higher
pressure drop is required on the balancing valve, the
computing will be restarted with an increased pressure drop
in the last branch. The balancing stops when the minimum
number of branches is not balanced.
4. The result of balancing
appears in the State field in
the Start Balancing
window.

Project with Central Pressure Input
We often come across systems with a central pressure input
with a distribution of the medium to either side of the input.
It is possible to balance such project by virtually dividing it
into two separate projects with
unidirectional branch distribution. The two projects are
measured and balanced individually and subsequently
drawn together using the Bind Projects command as
follows.

Replacement of sintered filters
When PFM 5000 Standard starts reacting slowly to changes in pressure or
when after powering up the pressure displayed exceeds 5 kPa, it is
necessary to change sintered filters as shown in the picture below. If there
is no improvement, please return to the manufacturer for servicing.
