Coriolis Flow Meter - RotaMASS 3-Series

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.

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. The state of the art converter provides a wealth of features including remote configuration via HART, multiple languages, advanced diagnostics, infrared programming and a four-line display for easy setup and operation.

High Pressure Hydraulic Oil

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.

Metering cryogenic fluids using the Rota MASS coriolis flow meter

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.

Metering High Temperature Fluids with the RotaMASS Coriolis Flow Meter

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.

Net Diesel Fuel Consumption

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).

Recycled Oil Containing Water

The use of recycled oil as an energy source presents a significant processing problem. ADMAG CA has been shown to provide reliable and stable flow measurement of recycled oil containing water.

Rotamass - Flue Gas Desulfurization

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.

Used Oil Refining

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.
