Flow-X IO Functions - fxSetPulseOutput
Calculations
Every calculation cycle a number of pulses is added to the reservoir that is equal to input value
'Increment' divided by input value Significance factor.
fxSetPulseOutput
Adds pulses to the reservoir, to be output on the next cycle. Takes the ‘significance factor’ into account,
see fxPulseOutput.

fxPT100Input
Each flow module provides 2 inputs for Pt-100 sensors.
A Pt-100 sensor is a Platinum Resistance Thermometer (PRT) element with a resistance of 100 Ω at 0°C.
'Pt' is the symbol for platinum.
Resistance thermometers as such are also referred to as Resistance Temperature Detectors (RTD).
The resistance changes linearly with temperature. For Pt-100 elements the linearity coefficient is 0.385
Ohm/°C for European elements and 0.392 Ohm/°C for American elements
For each sample the temperature value is obtained from the measured Ohms by means of the standard
RTD quadratic equation.
The input signal is considered to be faulty when the input circuitry has an open or a short circuit or
when the measured value is outside its range (as defined in table below).
