Operating instructions for KME flow meter for compressed air and gases
2 Product description
The KME flow meter operates on the thermal mass flow measurement principle and is suitable
for measuring the flow of compressed air and gases in pipelines. It can be used for measuring
the consumption of compressed air, nitrogen, argon, oxygen, CO2 or other non-corrosive and
non-flammable gases.
The KME measures the volume flow under standard conditions. The standard conditions
according to DIN 1343 (1013.25 mbar; 0 °C) are factory-set. Additionally, KME measures also the
mass flow, the standardized flow and the temperature.
KME has two signal outputs which can be configured as an analogue output (current), switch
output or pulse output for consumption metering.
The KME features an integrated consumption meter. The consumption volume can be shown on
the display and is retained even if the supply voltage is interrupted.

2.1 Modular design
One and the same transmitter can be used for each of
three pipe diameters:
KMe-715/-720/-725:
DN15 (1/2“) / DN20 (3/4“) / DN25 (1“)
KMe-732/-740/-750:
DN32 (1-1/4“) / DN40 (1-1/2“) / DN50 (2“)
The pipe diameter is easily changed via the display
menu or the Configurator software.
Once the gauge mounting block is mounted in the
pipeline, the transmitter can be installed and removed
without disconnecting the pipeline. As a result, the KME
is also ideal for temporary measurements or mobile use.
The sealing plug included in the scope of supply allows for operating the compressed air or gas
network even without the transmitter.
