Operation
3.1
Powering up and powering down
It is recommended to turn on power before applying fluid pressure and to switch off power only after relieving fluid pressure.
When applying pressure, avoid pressure shocks and bring the fluid system gradually up to the level of the specified
operating conditions; open the fluid supply gently.
3.2
First use
Bronkhorst does the utmost to ensure that you receive a clean product.This does not, however, relieve the end user of the
responsibility to ensure that the instrument and the system in which it is incorporated meet (hygiene) requirements that
apply to the intended use of the instrument. The responsibility for cleaning the equipment to meet such requirements lies
exclusively with the end user.
Before starting measurement and control, make sure to remove gas from the fluid system by flushing all fluid lines with the
process fluid at a relatively high flow rate.
For instruments with a control function, the highest possible flow rate is ensured by giving setpoint = 100% or using special
= 8 (valve fully open). Control mode 8 bypasses the PID controller, which is particularly useful when having
the ES-FLOW™ set to a low capacity flow range.
