FB1151LT capacitive flange liquid level transmitter | FB1151LT liquid level transmitter | FB1151LT

★ Overview

FB1151LT liquid level transmitter is a field transmitter directly installed on pipelines or containers. Due to the direct contact between the isolation membrane and the liquid-phase medium, there is no need to use the positive pressure side

The pressure tube is used to measure the liquid level, pressure, and density of media such as high temperature, high viscosity, easy crystallization, easy precipitation, and strong corrosion, and then convert them into 4-20mA signals for transmission

Get out. The FB1151LT liquid level transmitter adopts standard flanges for installation and connection, with flat flanges and insert flanges for users to choose from. Install flanges according to ANSI 2-inch and 3-inch standards

4 inches, nominal pressure according to 150LB and 300LB standards. Flange diaphragm materials include 316L, Hastelloy, Monel, Tantalum, etc.
