Compact flowmeter manages up to six common plant gases

1The ZFM Mass Flow Meters (photo) provides multigas, multirange functionality to 8 bars. This device currently handles up to six gases: nitrogen, air, oxygen, argon, helium and carbon dioxide). When the instrument is connected to the RS-232/RS-485 port of a PC or laptop, the accompanying ZFM configuration utility software lets the user select different gas types and flow ranges without removing the instrument from the installation. This flowmeter provides extensive self-diagnostic capabilities, and has an automatic sensor zero-offset adjustment (via digital interface or local pushbutton control), a digital interface and configuration port (optional Modbus RTU with isolated RS-485 tranceiver), and two programmable totalizers. Seven models are available. — Aalborg Instruments, Orangeburg, N.Y.
