- Integrated Rupture Disk: Standard safety venting protects site personnel during secondary containment overpressure.
- Total Insight Diagnostics: Continuous online checking of drive gain and tube integrity eliminates unplanned shutdowns.
- SIL 2 / SIL 3 Capable: Fully verified for emergency shutdown systems (ESD) and safety instrumented functions.
❌ Engineering Limitations (Cons)
- Upper Temperature Bound: Capped at +150°C (For higher temps up to +350°C, choose ROTAMASS Supreme).
- Weight Profile: Heavy-walled containment housing increases overall unit weight compared to standard meters.
- Higher Initial Capital Expenditure: Higher initial investment required due to thick-wall Hastelloy/316L metallurgy.

💡 Expert Procurement Guidance: Replacing Existing High-Pressure Flowmeters
When engineering a replacement or retrofit for an existing high-pressure meter (such as legacy Micro Motion or Endress+Hauser units), our technical team strongly advises verifying the following 4 parameters before issuing a Purchase Order:
- 1. Connection Profile & Pressure Rating: Verify whether your line uses 9/16" or 3/4" AutoClave high-pressure fittings vs. ASME Class 1500/2500 raised face (RF) or ring-type joint (RTJ) flanges.
- 2. Static Pressure vs. Hydrostatic Test Pressure: Ensure the 700 bar continuous limit covers your system's design pressure spike limits during pump startup.
- 3. Communication Protocol Alignment: Confirm whether your control room configuration requires HART 7, Modbus RS-485, Foundation Fieldbus, or PROFIBUS PA.
- 4. Hazardous Area & SIL Certification: Check if local site compliance mandates ATEX/IECEx Zone 1/2 or FM Class I Div 1 approvals, and verify if the SIL 2 safety manual is required for ESD loop integration.
7. Field Operations Guide: Preventing Gas Locking in High-Pressure Installations
In high-pressure liquid lines (such as chemical injection systems), vapor pockets or dissolved gases can break out during pump startup cycles, causing "gas locking" and drive gain spikes. Follow this engineering sequence to configure and vent the line safely:
Orient the Sensor for Liquid Drainage
For heavy liquid applications, install the ROTAMASS Intense sensor with the measuring tubes pointing downwards (flag orientation or bottom bent layout). This mechanical profile ensures that any tiny gas bubbles float up and out of the meter core naturally.
Execute Controlled Pressurization Block Flushing
Slowly open the upstream high-pressure valve to allow fluid into the system, keeping backpressure high. Run the chemical injection pump at a low volume for several minutes to compress and force out bubbles through a downstream bypass line.
Monitor Drive Gain Metrics via Total Insight
Access the Total Insight diagnostic dashboard. Check the raw Drive Gain value. A steady, ultra-low drive gain percentage confirms that the measuring tubes are entirely flooded with pure liquid phase, ensuring peak accuracy.
8. Frequently Asked Questions (Procurement & Technical FAQ)
Q: Why is the ROTAMASS Intense series uniquely optimized for high-pressure installations?
A: Unlike standard flowmeters whose measuring tubes can distort or burst under intense internal stresses, the Intense series is manufactured with heavy-walled measuring loops, reinforced secondary outer containment housing, and a built-in rupture disk natively supporting up to 700 bar (10,000 psi).
Q: Is the ROTAMASS Intense certified for safety-critical plant infrastructure?
A: Yes. The ROTAMASS Intense carries full Functional Safety assessment documentation with SIL 2 certification (and is SIL 3 capable when deployed in redundant 1oo2 configurations), making it fully compliant for installation in emergency shutdown systems (ESD).
Q: What calibration and quality traceability documentation comes with each unit?
A: All our Yokogawa ROTAMASS flow meters are 100% original, factory-fresh builds. Every instrument ships with intact serial numbers, factory hydrostatic test certificates, and formal EN 10204 3.1 Material Test Certificates (MTC).
