The FLD Helium-Series from DwyerOmega is engineered for high-purity helium gas flow measurement with direct-read, panel-mount convenience. Designed for applications where helium accuracy matters, the meter features a precision variable-area (float) mechanism within a rugged construction of 316 stainless steel or anodized aluminum. With a sapphire float and clear printed scale, users can quickly read flow rates with confidence.
Built for demanding conditions, the FLD Helium-Series supports process pressures up to 200 psi (13.8 bar) and temperatures to 121 °C (250 °F). The unit offers ±5% full-scale accuracy and ±0.25% repeatability, and a turndown ratio of 10:1 - giving broad measurement range with reliable precision. A 6-turn control valve is integrated for fine adjustment of flow.
Ideal for calibration labs, inert gas systems, leak-testing rigs or any helium-based flow application, the FLD Helium-Series delivers clear readout, high reliability and materials that resist helium’s unique properties and evacuation requirements. With a direct-read scale, panel-mount installation and robust construction, it brings simplicity and performance together for helium flow monitoring tasks.
