Section 1: Introduction

1.1 System Description

The instructions in this manual are for the AMETEK

Drexelbrook Universal IV for level measurement in liquids,

slurries, interfaces, and granulars.

Each system consists of a Universal IV two-wire, 4-20 mA

HART® electronic unit and a 700 series sensing element. A 380

series connecting cable is also supplied for connection of the

sensing element to remote electronic units.

The Universal IV system is an admittance-to-current transducer.

A change in level produces a change in admittance which results

in a change of current. It is termed a two-wire transmitter

because the same two wires that are used to power the unit also

indicate the change in level (4-20 mA).

Introduction

1.2 Technology

Capacitance

In a simple capacitance measurement, the capacitance increases as the

process medium covers more of the sensing element. In an insulating medium,

this is due to the increase in dielectric constant (k) from air to that of the

medium. In a conductive medium, this is due to the decreased distance from

ground as the medium provides a conductive path from the ground reference,

typically the vessel wall, to the outer surface of the sensing element

insulation.

This change in capacitance causes an imbalance in a capacitance bridge which

is detected in the circuitry and converted to an output proportional to level.

Radio Frequency (RF) Admittance

RF Admittance is the next generation. Although similar to capacitance it

adds a valuable feature, the ability to compensate for conductive coatings.

The patented Cote-Shield™ circuitry of the Universal IV Pro Model measures

resistance and capacitance separately. The level component of the sensing

element capacitance has a negligible resistance however, a conductive coating

will have a much greater resistance. The design of the circuitry also produces

signals for the resistive and capacitive RF currents of a conductive coating

to be of identical magnitude but of opposite phase. This allows the Universal

IV to subtract the effect of the coating and produce an accurate level

measurement even in the most difficult applications.

This patented Cote-Shield™ circuitry is designed into the Universal IV Pro

Model and enables the instrument to ignore the effect of buildup or material

coating on the sensing element. The sensing element is mounted in the vessel

and provides a change in RF admittance indicating the level of material.

The Cote-Shield™ circuitry prevents the transmission of RF current through

the coating on the sensing element. The only path to ground available for the

RF current is through the material being measured.

The result is an accurate measurement regardless of the amount of coating on

the sensing element. By far the most versatile technology available, it works

with all types of materials in a vast array of conditions; from cryogenics to

high temperature, and from vacuum to 10,000psi pressure.

Lite Model

The Universal IV Lite Model is the entry level RF Capacitance measurement

system for use where Cote-Shield™is not required. Lite models can be used

in non-coating and insulating coating applications. Universal IV Lite is not

recommended for use in conductive coating applications. In addition, the

Lite model has a 20-7,000 pF range that may limit the measurement span on

conductive liquids.

Pro Model

The Universal IV Pro model has the most versatility with full capabilities

of Code-Shield and measurement span of 1-45,000 pF. The Pro can handle

shorter and longer measurement spans and is compatible with a vast array of

applications.
