Section 1 Introduction
Figure 1-3 Model MT3750C with Reed Switch Alarm
Transmitter: 3750
The transmitter provides accurate magnet angle detection and conversion
to a 4 - 20 mA industry standard output signal, based on the position of a
float assembly in the flowmeter. This rugged, compact, microprocessor-
driven device is capable of providing accurate flow information to your
external support systems. The patented magnetic sensor with automatic
gain control enables an extremely high dynamic capture range without
sacrificing accuracy. (Refer to Figures 1-1, 1-4 and 1-5)
