PFM 1000 Measuring Instrument
Description
PFM 1000
Using the differential pressure measured by the measuring component in the system, PFM 1000 calculates the flow that runs through the
component (balancing valve or measuring orifice).
The application corrects the calculated flow also for anti-freeze mixes in cooling systems.
The flow can be measured in all branches of the whole hydraulic system and the whole system can be balanced.
The PFM 1000 has been designed to create hydraulic balance in heating, cooling and domestic hot water systems. It enables measuring of static pressure, differential pressure and flow.
PFM1000 components
•Main measuring unit
•Measuring needles & hoses
•Smartphone for displaying results and analysis (not included)
The main pressure sensor is extremely robust with a sturdy frame. Inside the pressure sensor is a differential pressure gauge with an integrated true differential pressure sensor for accurate digital data processing.
Conectivity between measuring unit and smartphone is wireless via Bluetooth.
PFM1000 can be connected to ANDROID and iOS devices using app downloaded from PLAY STORE (Android) or APPLE STORE (iOS)

Usage |
The PFM 1000 must be connected on the high |
How to measure: |
|
side as well as on the low side of the valve using |
1. Select manufacturer |
|
the appropriate needles, connectors and hoses. |
2. Select the type of valve |
|
If you are to measure under high static pressure |
3. Select the dimension of the valve |
|
it is recommended to connect the red hose first |
4. Select pre-setting |
|
in order to protect the membrane inside the |
5. Connect the valve to the pressure sensor |
|
pressure sensor. If you connect the blue hose first |
6. Zero adjust |
|
the pressure sensor may be damaged. |
7. Measure the flow |
|
You can read flow and pressure on the Android |
|
|
/ iOS smartphone which is separate from the |
|
|
pressure sensor. |
