Instruction Manual EL-FLOW® Prestige

9.17.084N

Numerous input/output options can be installed through the programmable 9-pin D-sub connector (from factory). In

addition to the various analog signal options and the standard RS232 communication, there are such options as RS485

communication, digital frequency/pulse output, alarm output/reset, valve purge/close and analog valve output.

Furthermore Bronkhorst offers various integrated fieldbus options: DeviceNet™, PROFIBUS DP, Modbus RTU/ASCII, EtherCAT®,

PROFINET and FLOW-BUS.

1.3.1

EL-FLOW® Prestige PI

The

EL-FLOW® Prestige PI

(pressure insensitive) adds active pressure compensation

to the already very accurate controlling characteristics, resulting in even more

accurate flow measurement and control stability.

An innovative static compensation algorithm ('FLUIDAT On Board') uses the actual

fluid temperature and pressure to calculate fluid properties in real time. Density,

viscosity, thermal conductivity and heat capacity of the processed media change

under the influence of pressure and temperature. The Fluidat On Board algorithm

continuously recalculates these properties and uses them to adjust the gas flow.

Dynamic pressure compensation detects rapid and large pressure changes (caused,

for instance, by operating multiple flow devices on the same fluid line, also called

the Crosstalk Pressure Effect) and adjusts the control signal in such a way that the

gas flow remains stable.

The

EL-FLOW® Prestige PI

is available with a choice from two different pressure sensors (up to 10 bar(g) and up to 100

bar(g)), both of which apply static compensation. The 10 bar type also uses dynamic compensation.
