SUPERtrol II Flow Computer Simplifies Energy and Environmental Monitoring |
|
Rising energy prices make it important for large industrial facilities with multiple buildings and large campuses to accurately monitor energy consumption. Repeatable, reliable flow measurement is a critical element in the implementation of these processes.
The SUPERtrol II Flow Computer can be used in such applications for computation of heat flow, mass flow, and corrected volume flow. It can also be used for data logging, communication, remote metering, alarming and control functions.
The following Application Notes describe two successful solutions utilizing the SUPERtrol II Flow Computer. |

HEATED/CHILLED WATER
This application note describes a Chilled Water Metering System using a magnetic flowmeter, two temperature transmitters and an electronic flow computer.
The SUPERtrol II multi-function flow computer monitors volumetric and mass flow of water, liquid sensible heat, and delta heat. It can be easily incorporated with a remote PC, modem, and remote metering software. |

 STEAM MONITORING
A typical steam monitoring system consists of a vortex flow meter, a static pressure meter, and an electronic flow computer.
Here the SUPERtrol II flow computer performs the necessary calculations needed to compute the steam energy and mass flow from the electrical signals it receives. Measured parameters include uncompensated volume rate, mass rate, temperature, pressure, density and enthalpy.

| TUTORIAL: Metering Industrial Gases and Flow Computations |
|
Gas metering computations are much more complex than simple liquid computations. There are a wide variety of industrial gases and each one brings its own metering challenges. To achieve accurate flow measurement and flow computations, one must challenge certain assumptions, based on the gas type as well as the line pressure and temperature in the application.
This tutorial discusses a variety of issues associated with gas flow measurement and flow computing, and examines the following topics:
- Ideal Gas Law
- Real Gases
- Gases Under High Pressure
- Gases Near the Liquid/Vapor Boundary
- Gas Mixtures
- Humid Gases
- Natural Gas
