1. GENERAL
Dedicated for steam service, this computer accepts signals from a steam service delta flowmeter. It
contains a microprocessor to perform steam pressure setting relative to service pressure, size (nominal
bore) setting and meter error adjustment, and indicates the total flow in terms of weight for accurate,
precise flow measurement.
