SITRANSFCT030

概述

FCT030 is based on the latest developments within digital signalprocessing technology – engineered for high measuring performance,fast response to step changes in flow, fast dosing applications,high immunity against process noise, easy to install commission andmaintain.

The FCT030 transmitter delivers true multi-parameter measurementsi.e. massflow, volumeflow, standard volumeflow, density,temperature and fraction.

The FCT030 IP67 transmitter can be remote connected or compactmounted with all sensors of type FCS300 sizes DN 15 toDN 150, FCS400 sizes DN 15 to DN 50, MASS 2100DI 1.5, DI 3, DI 6, DI 15 and FC300DN 4.

Fraction

The transmitter FCT030 can be set up at works to measure and reportvarious fraction concentrations of two-part mixtures or solutions.Where a discrete relationship exists between concentration anddensity at particular temperatures a calculation is performed andthe percentage concentration by volume or mass of Part A or Part B(100 % minus Part A) is measured. For solutions and somemixtures the total mass, or dry weight, is also available.

In some industries, a selection of standard density scales has beenadopted to represent the density or relative density of the processfluid.

If "Standard fractions" option is chosen at ordering, the followingfraction or standard density scales can be selected in the setupmenu:
