Nice video, Sir.

Plz recommended for dp measurement hand book, in which all level calibration methods available with an example

Not clear at all mate...

You should mention SG. of liquid in the tank. H = P/SG

We need another one for interface level water and oil

Practical implementation becomes problematic

If your controller PV scale is in percent, the transmitter range 20-80, and the level 75 cm, what should the PV indicator read?

wrong ans

What is 12in

Oversimplified explanation Exactly how are the lead resistances subtracted

Can you explain with example ?

Can you please post video on remote seal diaphragm level transmitter calculations

Hi Stuart.... your video is very cool in that a 3 wire RTD does compensate for the added resistances of long lead wires. .. I do have some problems with your math from 0:28 seconds forward. When you talk about a "resulting" resistance = R(b), where exactly would you measure this reisistance? It's not as simple as "adding" R2 in both sides of your equations, as R2 is "shared" by the other 2 legs and therefore your math is suspect???? Illustrating the cancellation effect of the lead compensation using voltage calculations would be more effective and correct. Anybody else out there caee to comment?

Why we took SG 1.8 for water. ??

Great information

Why the SP gravity of wet leg 1.8?

Thanks for sharing, marvelous explanation.

What is LRV

Is a great video if I have a sp propane 0.59 what will be my wet leg sp gravity?

Thank you Stuart for pure English! Thank god! I am seek and tired of indian and arabic technicians pronunciation. Why is specific gravity ever used instead of pgh equation?

Succinct. Thanks. The root words give it away: water, unchanging, force. Thus, in a given liquid, the constant force pressing against its container may be determined by considering how the liquid's density is being affected by the weight of its own mass. Hope I'm thinking about that in the right way.

If I have tank 5 meters how to obtain?

Thanks for information

What about dry leg ?

Thank you

Good job 👍

This makes no sense, how is your wet leg 1.8sp? So your wet side is the low side. The tank is variable, level will change. If the wet leg is full then shouldn’t it go to the high side and the bottom tap go to the low side which will be lower in pressure that the wet leg?

P=p(row)*g*h

Good, I told the shift foreman the right thing last night

Why subracting R2, R3 the logic behind it, I did not get

Thanks bro

Nice simple short vid that gets straight to the point

where do the 12 inches come from?

Hi, How we can calculate percentage corresponding to Ma? If 50 % means how many Ma?

Please can you talk about GWR and best brand for interface also talk about calibration

how i put it in the bridge circuit

Hi stuart, can you please let me know how to measure/check the resistance of R(b) practically. the remaining lead resistances (i mean Red, White1, white2) we will measure from multimeter) what about R(b)?

What is the best intermediate fluid used to fill an LP joint for a device that measures the level of LPG

big boy knowledge

debería tener subtitulos en español, todo lo bueno en ingles. gracias asi entienda solo una parte jejej.

Does the angle of the tube matter? Could I use this application to measure the depth of a lake at a certain point? (End of a pier) Would the tube have to be mounted perfectly vertically at 90 degrees at the end of the pier or could the tubing be sloped from the edge of the lake, extending to the end of the pier, with the DP transmitter at the shorline? How well do you think the DP could handle small waves at the water's surface?

thank youu so much bruhh....

Thank you and I love you

Where did you get 12 inches since it's not given?

Thanks a lot brother..your explanation is crystal clear

please add absolute transmitter calibration, since most people are not familiar in that subject.

What is the use of flow controller and how to determine the required flow rate for this purpose

Veeeery helpful thanks

Where from this 12" come from?

im puzzled, is this what happening in the bridge? voltage divider? is that d same? thanks
