STACK-probe

Product Type: Flow Measuring Insertion Probe
Technology Type: Cantilevered or End-Supported Air Traverse Probe

Get worry-free flow monitoring with this rugged instrument that can be easily installed for stack flow monitoring typical to Continuous Emissions Monitoring (CEM) systems.

The Air Monitor STACK-probe is an airflow traverse probe based on differential pressure (Pitot-Fechheimer) technology for measuring airflow; the same technology that will be used during the certification process to verify relative accuracy of the flow monitoring system. Each STACK-probe consists of two separate round tube self-averaging manifolds; one to measure the stack total pressure, and the other to measure stack static pressure. Multiple Pitot-Fechheimer ports are positioned on each manifold on an equal area basis (for rectangular stacks) or on an equal concentric area (for circular stacks). Similarly, average stack temperature is measured using a temperature probe with multiple sensing elements spaced along the probe length.

– Low maintenance with no-moving parts design
– Rugged and structurally designed for challenging process conditions

Features and Benefits:

Structurally designed for cantilevered applications allowing simple installation through a single insertion port.
Built-to-last in corrosive environments with 316 stainless steel and Hastelloy materials.
No initial or periodic calibration is required to measure flow accurately.
No moving parts or active electrical circuits for low maintenance.
