The Yokogawa ROTAMASS Intense series is specifically engineered for critical high-pressure containment environments where standard Coriolis flowmeters experience structural fatigue or metrological dropouts. Designed to manage fluid and gas loops at extreme operational limits, the Intense series features a reinforced sensor enclosure capable of withstanding working pressures up to 700 bar (10,000 psi), making it the industry benchmark for oilfield chemical injection, industrial gas bottling, and high-pressure hydraulic loops.
Driven by Yokogawa's advanced Total Insight (TI) technology lifecycle platform, the ROTAMASS Intense provides more than just standard mass flow tracking. It delivers synchronous direct multi-variable measurement of mass flow, density, and temperature, from which it continuously computes real-time volume flow, reference density, complex fluid concentration matrices, and inline viscosity for Newtonian liquids.

In high-pressure liquid lines (such as chemical injection systems), vapor pockets or dissolved gases can break out of solution during pump startup cycles, causing severe "gas locking" errors inside Coriolis tubes. Follow this engineering sequence to configure and vent the line safely:
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.
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 any remaining atmospheric air bubbles through a downstream bypass line.
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 the system is optimized for high-precision accuracy.

• For low-flow bench scale test loops and ultra-low fluid micro-dosing applications, explore the Yokogawa ROTAMASS Nano.

Request a Rapid Technical RFQ (Quotes in 2 Hours)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. It natively supports working conditions up to 700 bar (10,000 psi) while maintaining strict metrological tracking.
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). This makes it fully compliant for installation in emergency shutdown systems (ESD) and high-integrity pressure protection arrays.
A: Absolutely. All our Yokogawa ROTAMASS transmitters and sensors are 100% original, brand-new factory builds. Each unit ships with its factory serial numbers intact, formal hydrostatic pressure validation reports, and EN 10204 3.1 Material Test Certificates (MTC) to fulfill strict compliance audits.
