Introduction PFM 5001 has been designed to create hydraulic bal-
ance in heating and cooling systems. It enables mea-
suring of pressure, flow and temperatures in a system.
Using differences in pressure, PFM 5001 is capable of
turning these two pressures on both sides of a valve
into flow. Flow through individual branches of the sys-
tem can be measured, creating perfect balance in the
whole system.
PFM 5001 has a number of key features, that makes it
easy to use.
Complete set of PFM 5001 consists of:
two separate measuring units - measuring unit for
measuring pressure, flow and temperature
computing unit for displaying results and data
analysis
convertor
routers, max. 3 pcs – optional accessories
The main pressure unit is extremely robust, with a
sturdy frame. Inside the measuring unit is a hydraulic
part with an integrated true differential pressure
sensor for accurate digital data processing.
The flow meter automatically corrects the flow for dif-
ferent types of mediums being measured, such as an-
tifreeze liquids in cooling systems.
PFM 5001 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 5001 utilises a
sophisticated method for calculating hydraulic resis-
tances within the system. As a result, the PFM 5001
comes up with a proposal for the lowest energy loss.
This function dramatically decreases the time required
for balancing.
PFM 5001 has the advantage of high class digital tech-
nology, which enables 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 mea-
suring and to enable deaeration of the pressure hoses,
the main pressure unit is designed with incoming by-
pass for hydraulic zero setting.

Introduction
(continued)
This increase the base accuracy of the measurement.
The PFM 5001 can be supplemented with an external ther-
mometer connected via a coaxial connector. The tempera-
ture of the working medium can easily be measured by in-
serting the thermometer into the measuring nipples of the
valve, were you normally insert 3 mm measuring needles.
Specifications for valve manufacturers are pre-pro-
grammed in the memory of the PFM 5001.
The autonomous measuring mode of PFM 5001 allows in-
dependent data recording based on a pre-programmed pe-
riod. The acquired data are initially saved in the measuring
unit and can subsequently be analysed in computing unit .

Switching on
and off 1. Press ON/OFF button to switch on PFM 5001. The
sensor switches off automatically 60 minutes after the
end of communication with Smart phone.
Introduction
HEC
Getting
started 1. Smart phone has touch-sensitive display and usually
three basic buttons:
Home – it serves for return to Smart phone main
window.
Back – it returns the current window back. While
application is running, you can return up to the phone
main window and application stops.
Menu – phone or application menu.
. Insert SIM card to your Smart phone. 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 Smart phone activation. Next amount of data
will be charged during PFM 5001 application download.
