INTRODUCTION

The CIDRA Corporation SONARtrac

Model HD VF-100 Flow

Monitoring System (High Dispersion Volumetric Flow) is used to
provide accurate and reliable process flow measurements for difficult
to characterize solid/liquid mixtures and challenging sand/rock slurry
flows with varying velocities and densities within process pipes. The
SONARtrac

HD VF-100 utilizes patented array processing

techniques to listen to and interpret flow turbulence generated by fluid
flow. The clamp-on design eliminates the need for cutting pipe or
interrupting process flow during installation.

The SONARtrac

HD VF-100 consists of a common transmitter and

sensor heads sized for different pipe diameters.

SONARtrac

process meters certified for use in hazardous areas are

rated for use in Class I, Division 2, Groups A, B, C, and D
environments (per US and Canadian standards).

This manual covers the basic installation and setup of the
SONARtrac

HD VF-100 Flow Monitoring System. In all cases, local

safety and operating practices take precedence over the information
contained within this document.

Sensor Head Description and Function

The SONARtrac

sensor head contains no moving parts. The sensor

head includes a sensor band and a fiberglass or stainless steel cover
assembly to protect the sensor band. The sensor band is wrapped
around and clamped onto the process pipe. A multi-conductor cable
electrically connects the sensors to an electronic module mounted in
the cover assembly. Signals from the electronic module exit through a
NEMA 4X rated connector mounted to the outer surface of the cover
assembly.

1.2

Transmitter Description and Function

The SONARtrac

transmitter receives electrical signals from the

sensor head. The signals are processed using SONARtrac

array

processing firmware that displays the calculated results on an integral
LCD screen. Results can also be transmitted using the 4–20mA
analog output, pulse output, alarm output or the RS-485/232 digital
output. The electronic assembly is housed in a rugged NEMA 4X
enclosure.
