NEMA 4X Large Display Batcher
TEK-BATCH 7900B SERIES NEMA 4X LARGE DISPLAY BATCHER
The Tek-Batch 7900B satisfies the instrument requirements for a variety of flow meter types in liquid batching applications. Multiple flow equations and instrument functions are available in a single unit with many advanced features. The large digit 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 LDB permits a wide range of functions within the instrument’s attractive wall mount 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.
