Analog thermal mass flow-meter Aalborg

AALBORG®'s enhanced model GFM is a low cost, self-contained THERMAL MASS FLOW METER designed to accurately measure the flowrates of gases.

A tiltable LCD readout is built into the top of the meter. Readings are in direct engineering units in terms of specific gases. Remote reading installations are possible by means of an optional extension wire supplied with a modular phone plug.

Flowrates are unaffected by temperature and pressure variations.

Aluminum and stainless steel models are offered. Zero and span adjustments are conveniently accessible from the outside, a dip switch is added for external adjustment of decimal point of the LCD readout.

Optional rechargeable battery kit is available for portability.
