The Model GFM is a low cost mass flowmeter with digital readout for gases. Each meter incorporates an advanced straight tube sensor. The LCD readout is removable for remote reading installations, a feature especially useful in instrument panel designs. The flowmeter is made from aluminum, and had direct reading displays. The flowpath consists of anodized aluminum, 316 stainless steel, brass and O-rings made from Viton®. 1⁄4” fittings. The flowmeter is powered by a power supply transformer or rechargeable battery pack, which must be purchased separately.
