1. INTRODUCTION

Application

The VF04 2-wire level instrument uses the Time Domain Reflectometry (TDR) measuring principle and two-wire technology for level measurement.

It is designed for measuring the distance, level and volume of liquids, pastes, slurries and powder products.

The device operates in a tank, silo, rigid pipe, process vessel and side chamber.

The device is HART capable, it can be programmed using a HART® Handheld Communicator (HHC) and HyView software supplied as standard with the instrument.

Operating principle

The VF04 2-wire guided microwave level transmitter uses the TDR (Time Domain Reflectometry) principle. The instrument sends low power nanosecond wide pulses

along an electrically conductive rod, cable or coaxial probe with a known propagation speed (the speed of light). As the pulse reaches the surface of the medium or

interface of two liquids (altered dielectric constant r), a part of it is reflected back to the electronic module. The size of the reflected signal depends on the dielectric

constant rdifference of the mediums or layers. (When measuring to the surface of still water through air the reflected signal's strength will be approx. 80% of the

emitted signal). The reflected pulse is detected as an electrical voltage signal and processed by the electronics. Distance is directly proportional to the flight time of the

pulse. The measured distance data is converted to a level then to a 4-20 mA current and HART signals and is displayed on the LCD display. From the level data further

derived measuring values can be calculated such as volume and mass. The TDR technology is unaffected by the other properties of the medium as well as that of the

space above it.

3.4SAFETY REGULATIONS FOR THE EX APPROVED UNITS

The level transmitter must be operated in an intrinsically safe circuit only.

The metal enclosure of the unit must be connected to the EP (Equipotential) circuit.

3.5 MAINTENANCE AND REPAIR

VF04 does not require maintenance on a regular basis. In some very rare instances, however, the probe may need cleaning to remove deposited material.

This must be carried out gently, without damaging the probe.

Repairs during or after the warranty period are carried out exclusively at the Manufacturer. The equipment sent back for repair should be cleaned or disinfected by the

User.
