Panametrics Gas Flow Ultrasonic Transmitter Features • Economical flow measurement in a compact transmitter The DigitalFlow XGM868 gas flow transmitter is a complete ultrasonic flow metering system for measurement of most gases including: • No moving parts • No pressure drop • Wide rangeability with 150 to 1 turndown ratio • Non-obstructive flow measurement • Tolerance to dirty streams • Low maintenance • Suitable for high temperatures • Two-path measurement available for maximum accuracy • Hydrocarbon gases • Vent gases • Biogases • Digester gases • Fuel gases • Waste gases • Incinerator air flow • Vapor recov

The DigitalFlow XGM868 gas ultrasonic flow transmitter is designed to measure the flow rate of virtually any gas. The DigitalFlow XGM868 flow transmitter offers a unique combination of rangeability, ease of installation, low maintenance and accuracy in a low-cost transmitter. The state-of-the-art XGM868 shares the many advantages offered by the other products in the Panametrics line of innovative ultrasonic flowmeters. The all-digital XGM868 creates no pressure drop; has no moving parts or parts that foul or collect debris; seldom requires maintenance; and provides reliable, drift-free...

Specifications Operation and performance Fluid Types Acoustically conductive gases Pipe Sizes 2 to 120 in. NB (50 to 3,000 mm) and larger Pipe Materials All metals. Consult Panametrics for other materials. Flow Accuracy (Velocity) ±1% to 2% of reading typical Accuracy depends on pipe size and whether measurement is one-path or two-path. Accuracy to ±0.5% of reading may be achievable with process calibration. Repeatability ±0.2% to 0.5% of reading Range (Bidirectional) –150 ft/s to 150 ft/s (–46 m/s to 46 m/s) Rangeability (Overall) 150:1 Specifications assume a fully developed flow profile...
