PFM 5001 Measuring Instrument
Brand: Danfoss
The PFM 5001 has been designed to create hydraulic balance in heating, cooling and domestic hot water systems. It enables measuring of pressure flow and temperatures in a system.
Using differences in pressure the 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.
Features- Separated main pressure sensor and converter
- Data analysis based on Android smartphone (not iPhone) or pc via Bluetooth
- Upgradable with additional sensors and routers to extend range
- Possible to choose from different pressure sensors (kPa, bar, etc.)
- Accurate pressure measuring with true differential pressure sensor and 24 bit ADC
- Hydraulic by-pass for exact small differential pressure measuring
- External PT-100 thermometer
- Working with projects
- Programmable autonomous recording mode
- Main sensor powered by rechargeable Li-Ion battery
