if in a level tx height is given, how u calculate the ranges
of the tx?

Answer Posted / s. kanniyappan

In case of Dry Leg
Span = (X)(Gl)
Hw at minimum level = (Z)(Gs)+(Y)(Gl)
Hw at maximum level = (Z)(Gs)+(X+Y)(Gl)

In case of Wet Leg
Span = (X)(Gl)
Hw at minimum level = (Y)(Gl)-(d)(Gs)
Hw at maximum level = (X+Y)(Gl)-(d)(Gs)

Gl=Specific gravity of tank liquid
Gs=Specific gravity of seal liquid
Hw=Equivalent head of Water
X=Max level
Y=Min level
Z=Distance b/w Datum and Transmitter.

Why does a pressure gauge installed on reactor, doesn't have any vent line below to release the pressure? Is it any kind of designing mistake or it actually does not require any vent line? And if it does not require any vent line below it then how we are gonna release the pressure built inside the pressure gauge?

I was working on calibrating turbidity transmitters endress+hauser at effluent polishing plant.We calibrated using NTU buffers.What happened is that when we immersed the sensor, everytime we raise and lower the sensor gradually, the reading will vary.my question is that is there any specifications on what is the required distance from the bottom of the container with buffer to the face of the sensor?Is it ok to install the sensor in a medium which has turbulence specially if bubbles are present?
