Vögtlin red-y compact GCM-A3ES-BN00 Digital Mass Flow Meter, Air 2–100 mln/min
The GCM-A3ES-BN00 is a micro-flow version of the Vögtlin red-y compact GCM digital mass flow meter, calibrated on air for a working range of 2–100 mln/min (full scale 100 mln/min). It is a self-contained, battery-powered meter with a touch display, so you can measure gas flow anywhere without wiring, a PLC or a PC.
How It Works
Both red-y families use a thermal MEMS sensor. A small heated element sits in the gas stream, and the gas flowing past carries heat away in proportion to its mass flow. Because the measurement is of mass rather than volume, readings stay stable as pressure and temperature change, and every instrument is calibrated with real gas.
Key Features
- Battery powered (standard AA) or Micro-USB, so it can be used without any wiring
- Touch display with automatic orientation
- Accuracy ±2.0% FS (Eco/Eco plus) or ±1.0% FS (Special, up to 50 ln/min); turndown up to 1:100
- Three configurable alarms: max, min, range and totaliser
- Plug-in modules for external power, alarm relays or 4–20 mA/pulse output
- Anodised aluminium or electropolished stainless steel body
- Real-gas calibration for air, O₂, N₂, He, Ar, CO₂, H₂, CH₄ and C₃H₈
Applications
- Laboratory gas dosing, analytical instruments, leak testing and micro-flow research
- Portable checks and audits of gas consumption
- Temporary installations and field service where no power is available
Frequently Asked Questions
What flow range does the GCM-A3ES-BN00 cover?
It is calibrated on air for 2–100 mln/min. The full scale is 100 mln/min, and the lower figure is the bottom of the guaranteed range.
Can the GCM-A3ES-BN00 measure gases other than air?
Vögtlin calibrates with real gas for air, O₂, N₂, He, Ar, CO₂, H₂, CH₄ and C₃H₈, with other gases and mixtures on request. Tell us the gas when you order.
Does it need external power?
No. It runs on a standard AA battery or Micro-USB. Optional modules add external 15–30 VDC or 100–250 VAC power, alarm relays or a 4–20 mA/pulse output.
Do you need a controller instead of a meter?
The red-y compact regulator GCR adds a precision needle valve for manual flow setting.
