FPD350
T5 McMenon Averaging Pitot Flowmeter FPD350
Averaging Pitot Tube - 2" Diameter Probe
Starting from:
$2,300.00
Categories:
A multi-point averaging pitot flowmeter designed to measure flow by sampling at several points across the pipe, yielding an averaged differential pressure signal proportional to flow. It provides stable readings and low permanent pressure loss.
The FPD350 T5 delivers reliable differential pressure flow measurement for a broad range of process conditions. With modular adaptability and strong repeatability, it suits continuous improvement programs and industrial upgrades across multiple verticals.
Built with Eleven57’s commitment to scalable, measurable instrumentation, the T5 supports balance-of-plant monitoring, cost reduction initiatives, and environmental data collection.
Applications: water/steam flow, chemical batching, mid-pressure process control, sustainability compliance initiatives.
McMenon FPD350 Averaging Pitot Tube – Comprehensive Specifications
Covers pipe diameters from roughly 2″ up to very large conduits; available in custom lengths and mounting configurations. Features bi-directional measurement capability (if required) and performs well at low Reynolds numbers (good for viscous flows). Typical accuracy ~±1% of flow (with calibration) and repeatability better than 0.2%. The sensor has no moving parts and requires minimal straight-run (generally a few pipe diameters) due to the flow averaging effect.

Industries & Solutions :
Used in many flow monitoring scenarios such as plant steam flow, furnace air intake, ventilation exhaust, and large-scale cooling or heating loops. Particularly beneficial in retrofits or space-constrained installations, since it imposes a very small pressure drop and tolerates flow disturbances better than single-point sensors.
- Manufacturing and assembly lines
- Water and steam utilities
- Food and beverage process control
- Mid-scale chemical and blending facilities
- ESG and plant-level environmental reporting
