| DigitalFlow™ XGM868i
GE Panametrics Gas Flow Ultrasonic Transmitter
Applications
The DigitalFlow XGM868i gas flow transmitter is a complete ultrasonic flow metering system for measurement of most gases including:
Hydrocarbon gases
Vent gases
Biogases
Digester gases
Fuel gases
Waste gases
Incinerator air flow
Vapor recovery
Stack gases
Other gases
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-the-art XGM868i shares the many advantages offered by the other products in the GE 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.

Note 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) |
|
|
Note 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 |
|
|
Note 3 Stated accuracy may be achieved with total straight run as little as 10D using flow profile correction - contact factory for details |
