What are the major applications of a differential pressure transmitter and how are they connected
Differential pressure transmitter
Used in three applications
Attribute measurement, flow, filters validity
It can be used three purposes
1- level measurements
2-flow measurements (r.m.s)
3- Filters clogged check
As indicated on the transmitter screen there is a unit (millimeter mm) so this shows that it is used to read the ratio
it Can be used to read an open tank level and don’t need to connect the Low side of the transmitter to the tank and be left, but the High side connects down the tank
And in case the tank is closed there are two cases
Dry leg (with no steam)
Fluids that won’t cause damage to the transmitter
The low side of the transmitter connects to the top of the tank
And the side is high down the tank
In case of steam (causing damage to the transmitter)
So be the delivery
Wet leg
This is in the case of steam so it needs to be condensed or steamed up the line of water and connect to the side Low
The other side of the High is delivered at the bottom of the tank
Apparently, one of the sides of the transmitter is open to the air
So it turns out this transmitter is used to measure tank level open
