Model BC Flow Totalizer, Ratemeter & Batcher

Brand: Niagara Meters

The BC Flow Computer satisfies the instrument requirements for a variety of flowmeter types in liquid 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 isolated Analog output can be chosen to follow volume flow, corrected volume flow, mass flow, temperature, 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 logging, transaction printing, or for connection to a modem for remote meter reading. 

Remote metering software available.
