Introduction

This manual contains description, specifications

and instruction for the installation, removal, and

operation of the OMEGA FP-6000 Series

Adjustable Brass Flow Sensor. Please read the

manual thoroughly. If you require further

assistance, please contact your OMEGA dealer.

1.1 Description

The FP-6000 Series is an insertion flow sensor

used to measure the flow velocity of fluids through

process pipes. The sensor insertion depth is

adjustable, allowing installation into metal pipes

ranging from 1

to 24 inches in diameter (1

to 36 in. for Hot-Tap). The Hot-Tap version

enables installation in active pipes, reducing

downtime to a minimum. Wetted parts include

C36000 brass, CD4MCu steel, tungsten steel,

Fluoroloy B, and Viton®.

The FP-6000 Series mounts on the pipe through

any standard 1

inch female pipe fitting. The

unit comes equipped with standard NPT threads

or optional ISO 7/1-R 1

threads.

1.2 Theory of Operation

Liquid flowing through a process pipe rotates the

sensor paddlewheel. An AC frequency is induced

into the sensor coil which is proportional to the

fluid velocity in amplitude and frequency. The AC

signal is then input to a control instrument where

the frequency is converted to engineering units and

used to display flow rate and control external

devices.

Patented open-cell rotor

design provides a linear AC

output over a wider velocity

range.
