PanaFlow HT

# Product Introduction
PanaFlow HT is a SIL-certified flow meter designed for liquid flow measurement under nominal temperature or extreme high/low temperature working conditions. As the first ultrasonic flow meter certified by SIL (Safety Integrity Level), this device is specially engineered for safety-critical applications such as flow measurement in coking plants. Its high reliability effectively reduces risks of casualties, equipment and asset losses, environmental pollution, and damage to corporate reputation. Meanwhile, it also delivers excellent performance in non-safety-critical scenarios that require reliable ultrasonic flow measurement.


# Features and Advantages
• Drift-free flow measurement
• No routine calibration required
• Maintenance-free operation
• Unlimited pipe compatibility
• Reliable measurement design – IEC61508 certified
• Flow measurement for ultra-high process temperature applications (600°C/1112°F)
• Flow measurement for ultra-low process temperature applications (-200°C/-328°F)
• Bidirectional measurement


# Product Parameters
## Product Specifications
### Fluid Type
Liquids: Sound-conductive liquids, including most clean liquids, as well as liquids containing a small amount of entrained solids or air bubbles.


### Flow Measurement
Patented Transit Time™ mode


### Size
Standard: 3 inches to 16 inches (80 mm to 600 mm)
Optional: Custom sizes up to 72 inches (1800 mm) available upon request


### Accuracy
±0.5% of reading
For nominal sizes of 3 to 4 inches (80 mm to 100 mm): Range 7 to 40 ft/s (2.13 to 12.19 m/s)
For nominal sizes of 6 to 36 inches (150 mm to 900 mm): Range 3 to 40 ft/s (0.91 to 12.19 m/s)


±0.9% of reading
For nominal sizes of 3 to 4 inches (80 mm to 100 mm): Range 3 to 7 ft/s (0.91 to 2.13 m/s)


Final installation shall meet the following requirements: The fluid flow profile is fully developed (typically 10 pipe diameters upstream and 5 pipe diameters downstream of the straight pipe section), and the fluid is single-phase.
Applications with piping layouts generating turbulence (e.g., two out-of-plane elbows) may require additional straight pipe sections or flow conditioning devices.
Larger size meters are available upon request.


### Repeatability
±0.25% of reading
For nominal sizes of 3 to 4 inches (80 mm to 100 mm), range 7 to 40 ft/s (2.13 to 12.19 m/s)
For nominal sizes of 6 to 36 inches (150 mm to 900 mm), range 3 to 40 ft/s (0.91 to 12.19 m/s)


±0.5% of reading
For nominal sizes of 3 to 4 inches (80 mm to 100 mm), range 3 to 7 ft/s (0.91 to 2.13 m/s)


### Range (Bidirectional)
0.1 to 40 ft/s (0.03 to 12.19 m/s)


### Turndown Ratio (Overall)
400:1


### Sensor System and Materials
Bundle Waveguide Technology™ (BWT) system probes and brackets: 316L stainless steel
Optional: Alternative buffer materials available upon request


### Sensor Temperature Range
Normal temperature for liquid: -310°F to 600°F (-190°C to 315°C)
High temperature for liquid: -310°F to 1112°F (-190°C to 600°C)
