Measuring device Danfoss PFM 1000 10 bar [8981176]

Easy-to-use PFM 1000 measuring device for measuring static pressure, differential pressure and flow in heating and cooling systems. The package includes a case with the PFM1000 measuring device, 2 AAA batteries, 2 R21 adapters, measuring hoses 2 x 1.5 m (red & blue), measuring needles and user manual.
The device's pressure measurement unit measures the pressure in the balancing components of water-circulating systems (e.g. in the balancing valve) and sends the measured values ​​to a mobile device running Android or iOS via Bluetooth. The free PFM1000 application, which can be downloaded to the mobile device, has a clear user interface, where valve selection from the image menu is easy. The software covers valves sold in Finland well. If for some reason the application does not include a valve, you can enter the valve's Kv value, and the application will calculate the flow based on this value. The PFM 1000 measurement unit is very durable, and its sturdy frame can withstand a fall from 2 meters.

The PFM 1000 measuring device is very accurate. Its accuracy is based on the following factors:
• Highly accurate pressure measurement using a differential pressure sensor and 24-bit processing of pressure sensor data.
• Possibility of zeroing the pressure difference for pressure measurement of very low pressure differences. The zeroing of the measurement is done in the hydraulic bypass of the pressure inputs.

The PFM 1000 device uses advanced digital technologies that compensate for inaccuracies commonly found in pressure measurements, such as temperature dependencies and measurement nonlinearity. Measurement data can also be saved independently and directly on the pressure measuring unit. The measuring unit has a timer circuit that allows you to program periodic recording of the measurement independently in the mobile device application. When the recording is complete, the measuring unit turns off and the recording remains stored in the measuring unit until the application reads it. It is also possible to save the current values ​​directly on the mobile device.
