Capacitance Level Pressure Transmitter with Flange Mounting Intelligent Type
1. Introduction
The mounting of ML3000S flanged liquid level transmitter executes ANSI standard. It has 3” and 4” flanged specifications and has 150LB(2.5MPa) flange class. Regarding to specific installation dimension, please see the bellowed drawing. If users apply GB9116-88 standard, please note: DN=80, PN=2MPa. Material of the contacting liquid diaphragm: 316L, Hastelloy C-276, Monel, Tantalum and so on.
If customer don’t have clear indication, we will supply mounting flange of 3” specification, 150LB and 316L contacting liquid diaphragm.
