About Flowmeter

Flow meters record air consumption of single machines or of entire network sections and expose leakage before it shows up on the energy bill. The units run on compressed air and neutral gases at maximum operating pressures of 8 to 16 bar, and part of the range measures down to -0.9 bar into the vacuum region.

What matters when choosing

• Size BG 0 to 4 sets the measurable flow rate. Choose it from the actual consumption of the machine rather than from the pipe cross section.
• Thread and DN: female threads from G 1/2 to G 2, male threads from R 1/4 to R 2 and nominal widths DN 8 to 50 mm are available. Small consumers connect through the Ø 8 mm push-in port.
• Analogue or IO-Link version: analogue fits existing current-loop evaluation, IO-Link delivers reading and diagnostics straight to the controller.
• Series FLUX, FLUX 0 or FUTURA together with the function set: pure flow meters exist alongside combined units with switching output, pressure gauge, thermometer and pressure switch.
• Protection class and housing: IP 65 in an aluminium housing for the machine floor, IP 40 in a technopolymer housing for protected installation.

Typical applications

• Metering consumption per machine to allocate compressed air cost
• Tracing leakage in network sections by comparing night and shift consumption
• Permanent monitoring of blow-off and purge air, where rising demand points to worn nozzles
• Energy efficiency projects that log trends through the control system
• Supervision of test and leak-check stations where a steady flow rate is part of the test condition

The intended medium is compressed air or neutral gas, and some units require oil-free compressed air. The 51 items in this group are manufactured in Italy, Germany, Taiwan, China and the USA.
