ROTAMASS is the integral and remote type Coriolis Mass Flow Meter. Both types have highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved.
Coriolis Flow Meter ROTAMASS employs a flame-proof type converter case suitable for use in the hazardous area together with its intrinsically safety type detector.
Coriolis Flow Meter ROTAMASS's signal processing, housing protection and its detector's special decoupling system against external loads and vibrations, realize high performance in real applications.
Details
The RotaMASS 3 Series mass flow meter features a heavy wall, seamless, dual tube design uniquely decoupled from any process vibration or pipeline stress guaranteeing reliability and output stability. Nine different detectors enable customization of the meter for the best combination of mass flow range, pressure drop, and accuracy at the lowest possible cost. The versatile RotaMASS can be used in the most difficult applications from cryogenics to molten liquids as well as sanitary applications and aggressive chemicals. With its multi-measurement and multi-parameter capability, the RotaMASS is essentially a process control station.

- Yokogawa's integrated solutions contribute to safe and steady production at gas liquefaction plant in Norway.
A power plant in the Northeast was under pressure to meet State EPA requirements of reporting fuel consumption (used for emissions monitoring). The issue was digging a costly trench from the pump house to the control room building in order to run fiber optic cable that delivers a flow meter signal to the plant's historian where reports could be generated. The cost would be $20,000.00 alone to dig the trench.
Flow measurement of high pressure hydraulic fluid to servos to monitor leaks can translate to huge savings. However, measuring these fluids can be difficult due to the high pressures involved and entrained air, moisture and contamination.
Liquid Nitrogen, Carbon Dioxide, Argon, Oxygen, and LNG/LPG are some examples of cryogenic fluids which are perfect for a Coriolis mass flow meter. Their fluid properties change wildly with small variances in temperature or pressure. The biggest problem is that most meters on the market literally freeze up and stop working when metering these fluids.
Molten sulfur, bitumen, pitch, paint resins and liquid toffee are just a few of the fluids transported at high temperature. Their fluid properties change wildly with small variations in temperature, which presents a problem for most metering technologies, while the coriolis flow meter is perfect for such measurements.
Flow Measurement of diesel fuel is a relatively basic flow meter application. However, measuring net fuel consumption on a 2.2 megawatt diesel generator is uniquely complex. The diesel engine requires a supply fuel line (fuel from the tank to the engine) and a return fuel line (fuel from the engine back to the tank).
Fossil fuels have long been used as a heat source in power generation. Coal is one of the more common fuels, but environmental concerns have led to a great deal of time, effort and money being spent on the reduction of pollutants resulting from the use of coal.
Necessary oil is a family owned oil re-processor with a presence in the states of Tennessee, Virginia, North Carolina, South Carolina, West Virginia, Kentucky, Indiana, Ohio, and Pennsylvania. A fleet of trucks pick up used oil and discarded coolant from oil change shops and industrial users.
The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Therefore, since being introduced for practical use in the late 1970s, its market has rapidly expanded in many industries such as oil, chemicals, and foods.
