Introduction

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 11/2 to 24 inches in diameter (11/2 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 11/2 inch female pipe fitting. The unit comes equipped with standard NPT threads or optional ISO 7/1-R 11/2 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.
