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. 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)
