The KEP MS-748 SUPERtrol-I flow computer satisfies the instrument requirements for a variety of flow meter types in liquid, gas, steam and heat applications. The MS-716 includes many advanced features as well as multiple flow equations-- all in a single instrument.
The alphanumeric display of the KEP MS-748 SUPERtrol-I flow computer offers measured parameters in an easy to understand format. Manual access to measurements and display scrolling is supported. The versatility of the flow computer permits a wide measure of versatility within the instrument package. The various hardware inputs and outputs can be "soft" assigned to meet a variety of common application needs.
The user "soft selects" the usage of each input/output while configuring the KEP MS-748 SUPERtrol-I flow computer. The isolated analog output can be chosen to follow the volume flow, corrected volume flow, mass flow, temperature, pressure, or density by means of a menu selection. Most hardware features are assignable by this method.
The user can assign the standard RS-232 Serial Port for external datalogging, transaction printing, or for connection to a modem for remote meter reading. A service or test mode is provided to assist the user during startup system check out by monitoring inputs and exercising outputs. The system setup can also be printed.
