FLOWSIC600
|
|
| |
Ultrasonic Gas Flowmeter The FLOWSIC600 measures the actual volumetric flow rate, actual accumulated volume, gas velocity or velocity of sound in gases with high measurement acuraccy over wide measuring ranges. It is ideal for flows with high dynamics. The FLOWSIC600 2PLEX is ideal for custody transfer because of its 4-path meter for billing and the integrated 1-path meter for monitoring of internal faults.
The FLOWSIC600 is designed for uni- and bi-directional gas metering in pipelines up to DN 1200 (48") and pressure loss free installation. Its low energy consumption allows operation with solar energy. Applications The FLOWSIC600 is suitable for custody transfer metering, for company internal metering and billing as well as for automatic control and measurement tasks in the process measurement.
Fields of application are all divisions of natural gas industry, power plants, the chemical and petrochemical industry, the cement and other consuming plants.
