• Measurement of norm volume flow In the

nnnn

measuring range 6.7 to 27500 m3/h (DN65

nnnn

to DN350 or 21/2"-10"); consumption quantity in

nnnn

Nm3; media temperature in °C

nnnn

• Exchangeable fittllng: Probe removal under

nnnn

pressure possible (testo 6447 only)

nnnn

• Material selectable betwen galvanized steel and

nnnn

stainless steel

nnnn

• Sensor positioned exactly In measurement stretch

nnnn

with defined Inner diameter and volume flow

nnnn

adjustment ensure highest accuracy

nnnn

• Highest flexibility thanks to different signal outputs:

nnnn

- Analog output 4 to 20 mA (4-wlre )

nnnn

- Pulse output

nnnn

- 2 switch outputs (parameterlzable: consumption

nnnn

or volume flow-dependent, opener, closer,

nnnn

hysteresis, window)

nnnn

• Built-in totalizer, even without additional analysis

Specifications

nnnn

The compressed air counters testo 6441 to testo

nnnn

6444 are designed for the measurement, monitoring

nnnn

and recording of compressed air consumption, and

nnnn

therefore also for the determination of leakages in

nnnn

compressed air systems, consumption-based

nnnn

allocation of costs and the Implementation of peak

nnnn

load management. The compressed air counters

nnnn

testo 6441 to testo 6444 record norm volume flow

nnnn

according to the calorimetrie principle, which means

nnnn

the measurement procedure is Independent of the

nnnn

process pressure and does not cause a permanent

nnnn

pressure drop. The version testo 6447 offers

nnnn

everything the testo 6446 provides, In addition the

nnnn

removal of the probe under pressure is possible

nnnn

(patented screw fitting). The larger nominal values

nnnn

refer especially to Important compressed air

nnnn

pipelines, often the main supply line after

nnnn

preparation.

nnnn

Areas of application:

nnnn

• Leakage detection, compressed air consumption
