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)

Features

Usage

• Acurate pressure measuring with true
pressure sensor with 24 bit pressure
procesing.

• Digital compenstion of temperature effects
and the pressure sensor nonlinearity.

• Correction of flow calculation based on
antifreeze liquid characteristics.

• Compatible with Android (7,0+) and iOS
devices.

The PFM 1000 must be connected on the high
side as well as on the low side of the valve using
the appropriate needles, connectors and hoses.
If you are to measure under high static pressure
it is recommended to connect the red hose first
in order to protect the membrane inside the
pressure sensor. If you connect the blue hose first
the pressure sensor may be damaged.
You can read flow and pressure on the Android
/ iOS smartphone which is separate from the
pressure sensor.

• Wireless data transferfrom measuring unit to
mobile Bluetooth Low Energy technology.

• User-friendly interface.

• Easy balancing valve selection from a
photographic menu.

• A record of the measured values with the
capacity of up to 2,000 recordings.

• Can be used as data logger

• Very robust construction, can withstand fall
from hight of 2m.

How to measure:

1. Select manufacturer

2. Select the type of valve

3. Select the dimension of the valve

4. Select pre-setting

5. Connect the valve to the pressure sensor

6. Zero adjust

7. Measure the flow
