With PFM Flex you will discover a number of advantages over traditional instruments, such as:
An easy-to-use interface, step by step. All the most common valve brands are included in the data base, new valve manufacturers can easily be added.

Mobility – Wireless connection to the measuring sensor. A sensor can communicate with several hand terminals. Measurement of two valves can be made simultaneously by a person with a hand terminal and two sensors. Graphic balancing and on-line log. Create commissioning reports from stored valve readings. Our ambition is to create a quick and easy workflow where the result, documentation and balancing report are in place when the site is finalized.

A good way to streamline the workflow is to create an commissioning project. The object’s blueprint and documentation contain information about the valves’ calculated settings and design flow.

•  Hydronic Balancing PDF
• Hydronic Balancing Slideshow

The Hydronic Balancing document contains a methodology for proportional balancing using Lambda values, measured value / design value as a percentage of the design value. Measured value, input design value and Lambda value are presented on the Application program Flex 2 & Flex 4 measurement menu.

A two sensor setup and communication over several building levels makes commissioning faster and easier to perform. 

För-inställning metod

 The installer sets the flow of the valves based on calculated pre-setting from the engineers. A few test measurements and adjustments are made. The hydraulic behavior of the system always deviates from designed values. Accordingly, this method will not give an optimal result. 

 Proportionell metod

 All correctly working methods to balancing a system are based on the Proportional Method. All terminal units, branches and risers are balanced to the same proportion, or ratio, of designed flow. When the total flow is adjusted at the pump, all units will have the correct flow. 

Over night Log at a laptop is possible to display at a smartphone over long distance.

The combined DP & Temperature device (DPT) enables Power and Energy survey’s, temperature and DT Log’s.

With two terminal devices, smartphone & laptop it’s possible to display both balancing valve measurements at the smartphone screen.

As long as the Sensors are within the Bluetooth range two sensor can be displayed by Split Screen Multi Window at a Smartphone/tablet.
