INTRODUCTION
The Omega FTB-14XX-AMP Magnetic Pick-up with Preamplier was
designed to directly replace a standard pick-up within a turbine ow
meter when signal amplication is required. The pick-up is a combination of a standard Omega magnetic pick-up and a solid state electronic
preamplier in a single stainless steel housing.
OPERATING PRINCIPLE
As uid ows through the meter the turbine rotates at a speed proportional to the uid velocity. As each turbine blade passes through the
magnetic eld at the base of the pickup, an AC voltage pulse is generated in the pick-up coil. The voltage signal generated by these pulses
becomes amplied within the pick-up. The output signal generated
from the pick-up is now in the form of a square wave. The frequency of
this amplied signal is used to represent the ow rate of uid passing
through the turbine ow meter.

INSTALLATION AND WIRING INSTRUCTIONS
The FTB-14XX-AMP is simply threaded into the hole (⁄”-18UNF) in the
turbine meter until the pick-up bottoms out. Tighten the pick-up nger
tight. Do not over tighten.
Install the 3-pin connector in the proper orientation and connect the
wire ends of the cable using appropriate common wiring practices.
Refer to Table 1 and Figure 2 for wiring specications.
