Hi sir
For level measurement of boiler drum I want to instal DP transmitter at a low elevation of drum, and filled low side of transmitter with water by using condansate pod.
I calculated LRL and URL of transmitter.
When I looked at rosemount calculation document (attached file), there are small...
I think so
Last year we enlarged Yokogawa DCS system, we bought new FCS from Yokogawa to control new 400 IO in my plant , (last year we replaced 6th FCS ).
Our new FCS price is nearly with new ESD system .
I agreed with "Yokogawa is trying hard to buy market share by keeping their prices...
What do u thing about YOKOGAWA PROSAFE SYSTEM.
In my plant , we decided to change our emergency shut down system (now we have AGUST ESD sytem)with Yokogawa prosafe ESD system..
Can u explain what are the adventages or disadvantages Yokogawa Prosafe to Triconex.
Triconex ESD system is more...
fistly I set zero calibration , after I replaced seals on tank flanges.
I set zero at atmospheric pressure and are now checking zero at 21 bar with -27degrees celcius. but when I opened blocked valves, it gives AL30 and display of level - (minus) levels.
So I understood that, at 21 bar with...
yokogawa installed the seals on the transmitter.
so ? bought order code of EJX118A-DMSCG-912DB-WA22B1SW20-EA22 / KF21 / X2 .
,
yokogawa instlalled it in their factory.
You know that, my DP is filled with ethylen glicol.
its density is 1.09gr/cm3 at atmospheric temperature.
But after I replaced both of 2 seals. Fill fluid density will be changed. because temperature of tank has too low temperature.
But which density of fill fluid will occur.
The tank which...
DANW2 thank There will be another experiment tomorrow.
Can u look at attached file.
THANKShttp://files.engineering.com/getfile.aspx?folder=77b384a1-d1fd-42c2-a9cf-88a288440fb8&file=In_Area.JPG
this DP can work at 184mmH2O URV.
because As u see, ? make an experiment with this DP in my work shop.
Please look at pictures http://files.engineering.com/getfile.aspx?folder=3009d565-8e25-4394-bc7d-9f2a5bba0198&file=lab_experiment5.JPG
transmitter order code is written below
Brand:Yokogawa
Order Code: EJX118A-DMSCG-912DB-WA22B1SW20-EA22 / KF21 / X2
So flange sizes is 2" 300#
I know that there are 2 types of calibration.
firstly replace 2 flange neighbourhood (replace it on the same height) , make zero calibration as you...
I want to say process pressure, not URL value ,
process pressure is 21bar.
flange to flange distance is 35cm.
density is 0.52gr/cm3.
so span is : 35cm X 0.525gr/cm3= 184mmH2O
Secondly I replaced DP under high seal,
about 150mm above high seal
