SUPERtrol II (ST2) Flow Computers for Energy Metering of Steam and Heated/Chilled Water | |
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.

|
| ES749 - For General Utility Metering | | The workhorse of flow computers, the ES749 accepts common pulse and analog inputs from nearly all of the flow meters commonly encountered in utility metering of steam, heated and chilled water, industrial gases, and liquid flow applications. |
| ES759 - For Use in Combined Heating and Cooling Systems | | Designed for applications where the same system is used for heating during part of the year and for cooling during other periods, the ES759 provides separate totalizers for heating and cooling. |
| ES761 - For Net Energy Applications Using Multivariable Transmitters | | Designed for applications where there is a need to compensate saturated steam by temperature or pressure, and compute the net energy between the steam input to system minus the energy returned in condensate. |
| ES762 - For Energy Metering with Secondary Inputs | |
Intended for applications requiring additional analog inputs from the system or customer site, in addition to the primary steam or heated/chilled water computation. Two extra analog inputs and four additional totalizers can be used to aquire data and read locally, data-logged or accessed over available communication channels
