Introduction - K-TEK MT5000 Installation & Operation Manua

1.0

INTRODUCTION

Thank you for using the K-TEK MT5000 Guided Wave Radar Liquid Level Transmitter. The MT5000 series is a
second generation of products which have been designed for simplicity of setup while offering extensive
configuration capabilities. You are invited and urged to review this instruction manual in its entirety prior to use of
the transmitter. This will eliminate most installation problems due to improper configuration.
We, the K-TEK Family, sincerely hope you receive many years of reliable use from the MT5000 transmitter and
welcome your feedback to consistently improve our all of our products. It is our desire to provide you, the user, with
the most reliable, customer friendly device to suit your application needs.
When it comes to measuring the level of liquids, guided wave radar technology now offers more level-detection
capabilities than ever before. For an ever-widening range of previously hard-to-measure products such as molten
sulfur, liquid ammonia and petrochemicals, guided wave radar transmitters provide accurate level measurements
even under harsh chemical environments, wide variations in operating temperatures and pressures, and low
dielectric constants. Great strides have also been taken in making these units easier to configure to a variety of proc-
ess applications coupled with the simplicity of integrating these devices with most digital communication protocols.
These improvements come as a welcome relief to process engineers that seek solutions to measuring the contents
of tanks, silos, hoppers, bins, mixing basins, and vessels in an expanded range of level applications across several
different industries.
Because a guided wave radar transmitter has no moving parts, it has established itself as a level measurement
technology that has distanced itself from traditional mechanical means, which don't hold up as well in dirty service.
Guided wave radar achieves its non-mechanical level detection capability by measuring the time of flight of the
transmitted signal.
Known more accurately as Time Domain Reflectometry (TDR), the process involves:
1. Sending microwave energy down into a vessel guided by an antenna.
2. When the pulse of radar energy reaches the product (indicated by a change in impedance), part of the
pulse is reflected back toward the transmitter.
3. A receiver measures the exact duration of time between the transmitted and reflected signal—the "time
of flight."
4. The device analyzes this time and ultimately displays the level of the product as a distance in inches,
feet, meters, or other engineering units.
The MT5000 transmitter was developed with ease of operation in mind. We made use of a graphic display to
vide a more user friendly aspect to the transmitter configuration. The graphic display allowed us to incorporate multi-
ple language options in the setup menu such as English, Spanish and Chinese. In the incorporation of the graphic
display, the electronics were converted to a digital format. This provided a greater signal recognition
and an ability to include an ―onboard oscilloscope‖ as an aid in troubleshooting tough applications.
The emphasis on simplicity extended itself beyond the use of multiple languages. The Basic Setup menu has been
designed with a series of multiple choice questions which, when answered correctly, will configure the transmitter to
the installation. The mA Output Setup menu has been expanded to include Loop Test and HART
capabilities.
Coupled with the development of the MT5000 series was the development of the KCOM™ software. KCOM™ is a
diagnostic tool which allows the MT5000 to be remotely configured using a computer and HART
Beyond the Basic Setup parameters, the software will allow the user to view the return signal of the MT5000 on the
computer screen. As a trouble shooting tool, a screen shot of the waveform may be taken and sent to the factory for
analysis. The KCOM™ software is free and may be downloaded from our website at www.ktekcorp.com.
