Optional Equipment
Transmitter
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.
