  • Durable acrylic housing includes hot-pressed, easy-read flow scales
  • Features accuracy within ± 5% of full scale

Terra Flowmeters are our most popular gas regulators for low-volume flows; they are suitable for total pressures up to 100 psig and temperatures to 150°F (66°C). Bodies are cut and precision-machined from solid, clear acrylic* blocks for easy visual inspection and maximum durability. Precision-machined bores provide accuracy to within ± 5% of full scale.

Two-inch reading scales are hot pressed into the plastic; front scale location and white background provide excellent visibility. Select from among three different flow ranges, according to enclosure size (see chart below).

Caution: Terra Flowmeters should not be used with fluids or gases that may attack acrylic plastic body.

*Acrylic is damaged by alcohol and other cleaning agents.
