The BCS500 Flow Computer satisfies the instrument requirements for turbine and other pulse producing flowmeters 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 BCS500 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 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 hardware features 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 or modem. Front panel selection of fluid type is supported. Up to 10 fluids can be stored in the unit
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 monitoring inputs and exercising outputs and printing system
