Features and Benefits:
- Automatic purging at regular field-selectable intervals. The AUTO-purge III utilizes short duration, high pressure (up to 125 psig) air to maintain signal lines and the sensing ports of the total and static pressure manifolds in a clean, unobstructed condition. The automated purge cycle can be programmed at user-selected intervals to achieve accurate measurement performance for the process flows with entrained particulates.
- Purge cycle protection of flow measurement. The last transmitted process outputs are maintained for the purge cycle for consistent flow data collection.
- Transmitter isolation from purge function. Solenoid piloted spool valves isolate and protect the transmitter while the high-pressure purge air forcefully flushes out all particulate matter on the measurement station or probe array.
