3 Description of the instrument
11
•
The display °C (LED4) cannot be selected.
Signal output 1
•
Switch signal is the limit value for volume flow, hysteresis or window
function as NO or NC contact
•
Pulse sequence for consumption quantity with 1 pulse/standard litre
(pulse length 2 ms) and 1 pulse/Nm³ (pulse length 100 ms)
Signal output 2
•
Switch signal is the limit value for volume flow, hysteresis or window
function as NO or NC contact
•
Analog signal (4 - 20 mA) for corresponding volume flow
•
Pulse sequence for consumption quantity with 1 pulse/standard litre
(pulse length 2 ms) and 1 pulse/Nm³ (pulse length 100 ms)

Compressed air counter
The compressed air counter may only be used for measuring the volume
flow of working compressed air with up to 16 bar positive pressure.

When using the totaliser function (consumption meter m³), the display value
must be multiplied by 1000.
As of DN 150 the display range with 4-digit representation of the m³/h is in-
sufficient. The display value is to be multiplied by 1000.
Based on the small size, the sensor only has a small contact surface. The
pressure loss is thus negligible (typ. 1 mbar).
