Application Examples of Totalizing Meters and Transmitters
Combining Two Totals
A+B, A-B, A/B and AxB arithmetic functions are available with
the Extended totalizing transmitter. A+B can sum two totals,
while A-B subtracts the outflow total from inflow total. A/B ratio
applied to two totals helps assure the proper mixing of
components.
Up or Down Counting with Preset
A single Laureate dual-channel totalizing transmitter will
handle two repetitive fill operations by counting from zero up
to a preset, or down from a preset to zero. The dual relay
option is required.
Machine ON Time and Utilization
An easy way to measure the ON time of machines is to count
AC line cycles and scale the total to hours. To display
machine utilization or duty cycle in percent, use the Extended
totalizing transmitter. Connect Channel A to switched AC and
Channel B to the AC line, and apply a 100 multiplier to the
A/B ratio.
Custom Curve Linearization
The Extended version of the Laureate dual channel totalizing
transmitter can transmit scaled rate or total for the same
channel at the push of a button, and alarm both the rate and
total. The Extended version can also do curve linearization,
thereby extending the working range and accuracy of flow
transducers.
