Gas flowmeter

The flowmeter bodies are cut and precision machined from solid, clear acrylic plastic
blocks. This construction not only produces a handsome finished product, but permits complete
visual inspection. As a result, the flowmeters are especially popular for medical and laboratory
equipment applications.

Scales are easy to read - The front scale location and white background provides excellent
visibility. The direct reading scales are hot stamped into the plastic and will not wear off.
Mid-range calibration is established with a master flowmeter.

Durable and attractive construction - The machined acrylic bodies of the flowmeters are
practically unbreakable. The tapered bore is precision machined to a smooth surface that provides
perfect visibility of the indicating float. The DFG 4T.6T.8T models are available with either brass
or stainless steel inlet and outlet connections and are tapped for 1/8" NPT thread. DFG 4T.6T.8T
models have either 1/4" back or 3/8" end connections. All standard models employ Buna-N o-rings
for leak proof operation and are available with either back or end connections for horizontal or
vertical piping. Precision metering valves in brass or stainless steel are available.
