Description: The ES-747 Flow Computer satisfies the instrument requirements for pulse producingflowmeters in liquid and gas applications. Multiple flow equations and instrument functions are available in a single unit with many advanced features. The alphanumeric display shows measured and calculated parameters in easy to understand format. Single key direct access to measurements and display scrolling is supported The versatility of the ES-747 permits a wide measure of versatility withinthe 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 instrument. The isolated analog output can be chosen to follow volume flow, corrected volume flow, mass flow, temperature, pressure or density by means of a menu selection. Most hardwarefeatures are assignable by this method. The user can assign the standard RS-232 Serial Port for data recording, transaction printing, or for connection to a computer. Front panel selection of fluid type is supported. Linearization options include UVC, Strouhal/Roshko and 40 point linearization tables. A Service or Test mode is provided to assist the user during start-up system check out by monitoringinputs and exercising outputs and printing system setup.
