. . . ADDENDUM FOR FLANGE-MOUNTED TRANSMITTERS
These models of differential transmitter are suitable for liquid level measurement.
The fluid, in this case, must be clean, free of solids and not viscous. This is because the process diaphragm is recessed in respect
to the flange face.
The differential transmitter has been designed to connect to a flanged tank nozzle, or similar ANSI (DIN) fitting.
Standard connections for 2/3-inch Class 150/300, and equivalent DIN, are available (see Figures 1 and 2).
This model is specifically dedicated to closed (pressurized) tanks (see Figure 4 and Applications n
°
2 and n
°
3).
