Abstract
Sistem pengendalian flow pada process control system plant
merupakan sistem yang digunakan untuk mengendalikan flow.
Pada perancangan sistem pengendalian flow ini, sensor yang
digunakan untuk mengukur flow adalah sensor flowmeter 1” yang
dilengkapi dengan rangkaian pengkondisian sinyal frequency to
voltage (FTV) dan rangkaian komparator. Rangkaian FTV
digunakan untuk merubah frekuensi ke tegangan, sedangkan
komparator digunakan untuk merubah sinyal analog output dari
FTV menjadi sinyal digital. Output dari sensor flowmeter akan
mengukur flow yang ada dan akan memberikan respon ke PLC
saat setpoint flow tercapai sehingga MOV sebagai aktuator flow
akan merespon. Dari data respon pengendalian yang didapat
menunjukkan bahwa pengendalian telah berjalan sesuai dengan
setpoint yang diinginkan yaitu 18 liter/menit dan berjalan dengan
stabil. selain itu berdasarkan pengujian alat pada sistem
pengendalian flow didapatkan respon time yang cukup baik untuk
mencapai stedy state dengan maksimum overshoot 19 liter/menit.
Waktu yang dibutuhkan untuk mencapai set point (settling time)
dari awal pengambilan data adalah ± 55 detik.

Flow control system in process control system plant is a
system that used to control flow. On designing control system
flow this, the sensor used to measure flow is sensors flowmeter 1”
equipped with a circuit of conditioning signals frequency to
voltage ( FTV ) and komparator circuit. A series of ftv used to
change frequency to voltage, while komparator used to change
analogue signals the output of ftv into digital signals.The output
of flowmeter sensor will measure flow will respond to plc when
setpoint flow achieved so MOV as actuator flow will respond.
From the data response control obtained shows that control has
been running in accordance with setpoint desired that is 18 liters
per minutes and walked with a steady. in addition based on
testing instrument in control system flow obtained response time
is a good enough to reach steady state with only a maximum
overshoot 19 liters per minute .The time it takes to reach set point
( settling time ) from the beginning of the data sampling is ± 55
seconds .
