Description

CT34SB is a specialized 2-channel fully programmable flow-rate totalizing counter. The instrument is especially designed to measure pulse signals from 2 different flow-meters according to the functional block-diagram below: Counter software allows a convenient programmable scaling of both measured flow signals and applying various calculations on both flow rates. CT34SB is equipped with two 6-digit LED displays indicating current flow-rates, mathematically calculated values as well as accumulated total counts. The counter has also an optional relay output for generating impulse when certain total value is reached (dosing function).
