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.

Getting started
1. Smartphone has touch-sensitive display and usually
three basic buttons:
Home – it serves for return to Smartphone main window.
Back – it returns the current window of a back. While
application is running, you can return up to the phone main
window and application stops.
Menu – phone or application menu.
2. Insert SIM card to your Smartphone. Unlock SIM card by
standard procedure for mobile phones.
Make sure that you have arranged internet services to your
SIM card due to downloading about 50 MB of data during
Smartphone activation. Next amount of data will be
charged during PFM5000 application download.
3. Create Google Account.
4. Fill requested fields.
