Flow station DS 300
with consumption counter
Consumption
DS 300 displays the actual value (m

/h,
m
3
/min) and the total consumption.
A 4...20 mA output for m

/h and a pulse
output for m

are available for routing to a
superior building management system
(PLC)
Special features
 Usable from 1/2” to 12” (DN 300)
 All-in-one solution, small
installation expenditure
 2 displays, actual flow and total
consumption
 Easy installation and removal of the
sensor under pressure
 Highest accuracy due to 5 point
precision calibration
 Output 4 to 20 mA for m

 Easy handling:
– Inner diameter freely adjustable
– in DS 300
– 2 alarm values freely adjustable
– Optical display in case of alarm
– Consumption counter resettable
 Dew point sensor connectable
Flow measuring ranges VA 400 for compressed air (ISO 1217: 1000 mbar, 20°C)
The large measuring range of the
consumption sensors enable the
recordings of high consumptions
(e. g. on weekdays) and the determination
of leakages of a few litres/min
(e. g. weekends).
Flow station DS 300 with
consumption counter
consisting of:
 Multifunction measuring
instrument DS 300
 Consumption probe VA 400
 Available with and without
measuring section
Installation even under pressure via
customary 1/2” ball valve
