Compact Orifice Plate - All in one
Starting from:
$1,200.00
Categories:
An orifice-based flowmeter assembly that combines an orifice plate carrier with an integral 3-valve manifold for direct mounting of a differential pressure transmitter. This creates a single, compact flowmeter unit for ease of installation.
The McMenon FPD175 is a cost-effective, space-optimized orifice plate flow meter designed to serve liquid, gas, and steam systems with both versatility and precision. Featuring an integrated orifice plate, DP manifold, and optional temperature sensor, this single-body solution simplifies installation, enhances accuracy, and minimizes maintenance.
Available in concentric and conditioning plate formats, the FPD175 offers excellent pressure recovery and requires less upstream/downstream piping than traditional assemblies. Designed for high-temperature resilience and engineered for ASME and DIN flange compatibility, it’s the smart choice for reliability across mid- to high-pressure environments.
Its compact design and optional remote mounting kits make it especially suitable for modular systems, confined spaces, and industrial modernization projects—reinforcing Eleven57 Energy’s mission to make high-performance instrumentation accessible and measurable at scale.
Applications: plant utility lines, steam monitoring, process control loops, compressed gas systems.
McMenon FPD175 Orifice Plate Flow Meter – Comprehensive Specifications
General Specifications:
Typically a wafer-style orifice carrier (sized for standard pipe diameters) that includes correctly positioned tap ports and a built-in block/isolating manifold. Allows a DP transmitter to bolt directly onto the assembly, eliminating impulse tubing. Supports various orifice bore sizes (for liquids, gases, or steam) and standard pressure ratings (often up to ANSI 600 or higher). Materials and flange ratings are chosen per application; assembly is usually leak-tested as one unit.

Industries & Solutions:
Used in applications where a traditional orifice + separate transmitter installation is impractical or space-limited. By combining the primary element and transmitter, it minimizes potential leak points and installation errors. Common for clean fluids (gas, steam, liquids) in industrial plants looking for a plug-and-play DP flowmeter solution.
- Industrial steam systems and district heating loops
- Chemical and petrochemical processes
- Compressed air and utility gas distribution
- Modular process skids and mobile equipment
- Energy optimization in legacy infrastructure
