DigitalFlow™ XGM868i Panametrics Gas Flow Ultrasonic Transmitter The DigitalFlow XGM868i gas ultrasonic flow transmitter is designed to measure the flow rate of virtually any gas. The DigitalFlow XGM868i flow transmitter offers a unique combination of rangeability, ease of installation, low maintenance and accuracy in a low-cost transmitter. The state-of-theart XGM868i shares the many advantages offered by the other products in the Panametrics line of innovative ultrasonic flowmeters. The all-digital XGM868i creates no pressure drop; has no moving parts or parts that foul or collect debris; seldom requires maintenance; and provides reliable, drift-free operation. The flow rate can be displayed locally or transmitted to a remote system via an analog or digital communications link.

DigitalFlow™ XGM868i Datasheet I PANAMETRICS • Economical flow measurement in a compact transmitter • Wide rangeability with 1500 to 1 turndown ratio • Tolerance to dirty streams • Suitable for high temperatures • Two-path measurement available for maximum accuracy All of the DigitalFlow XGM868i's electronic components are housed in a compact transmitter package that can be installed right at the flow measurement point. This greatly simplifies wiring of the transducers and results in trouble-free operation. In addition to the standard single-channel model, an optional two-channel model provides...

DigitalFlow™ XGM868i Datasheet I PANAMETRICS 1. Accuracy and sensitivity are dependent on pipe diameter, molecular weight and temperature. All accuracy specs assume molecular weights greater than 24 kg/kmole and temperatures less than 100 °F (38 °C) 2. Accuracy is dependent on straight run. All accuracy specs assume a fully developed flow profile or a minimum straight run of 20D upstream and 10D downstream 3. Stated accuracy may be achieved with total straight run as little as 10D using flow profile correction -contact factory for details
