Introduction PFM 5001 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 5001 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 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 different types of mediums being measured, such as antifreeze 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 resistances 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 technology, 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 measuring and to enable deaeration of the pressure hoses, the main pressure unit is designed with incoming bypass for hydraulic zero setting.

Introduction This increase the base accuracy of the measurement. (continued) The PFM 5001 can be supplemented with an external ther-

mometer 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 valve manufacturers are pre-pro- grammed in the memory of the PFM 5001.

The autonomous measuring mode of PFM 5001 allows independent data recording based on a pre-programmed period. The acquired data are initially saved in the measuring unit and can subsequently be analysed in computing unit .

Switching on and off

Introduction

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.

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.

2. 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.

3. Create Google Account.

4. Fill requested fields.

7. PFM 5001 main menu.

PFM 5001 application is installed on the Smart phone. You need only insert SIM card to phone and set up call and internet services.

It is necessary to create Google account if you want later download upgrades of PFM 5001 application.

8. Return to Smart phone Main Window by Back button.

Bluetooth settings

1. Enter Phone set up by Settings Button

3. Switch On Bluetooth.

Notice! Very important!

Before switch On the bluetooth connection you have to switch On the measuring units and wait for initalisation for 4s (green led diod stop blinking), after that switch On the convertor and again wait for initalisation. In the last step switch On bluetooth on your smart phone. If you don´t do that, you will not see (not find) the convertor and measuring units.

2. Enter Wireless & networks.

4. Continue by Scan for devices.
