Quick Setup
The procedures described in this section assume you will access the menu items
directly.
Setup
The minimum data needed to make a level measurement is listed below.
–Detector Length
–Minimum Span
–Maximum Span
–Level Type
Standardization Before the detector can convert the measured radiation value to a measurement of the
process level in the vessel, the amount of radiation arriving at the detector must be
measured for at least two known levels of the process material (tank empty and tank
full). Normally the standardization measurement is performed with the vessel empty
(process level at or below the bottom of the detector) when the maximum amount of
radiation reaches the detector. The standardization value establishes a reference
measurement point that can be easily repeated latter to maintain the calibration of the
detector. Once the standardization (0%) and calibration (100%) measurements are
complete, the detector uses these values to convert the measured radiation into an
indication of the process level. This level indication may be adequate for many
applications.
Calibration There are up to ten calibration points that can be performed on the process.
The ten calibration points allow you to have calibration points in the region of interest,
and can accurately achieve a good level reading in that region. Any buildup on the
vessel walls can also be calibrated to achieve accurate level readings. Remember that
each Cal Point must be higher than the previous Cal Point (i.e., Point 2 may only be
calculated after Point 1).

Thermo Scientific LevelPRO User Manual 1-1
Chapter 1
Product Overview
Introduction Note: This manual provides user instructions for the LevelPRO and
LevelPRO-T detectors. For the purposes of this manual, LevelPRO will refer
to the complete family of detectors, unless otherwise specified.
Thermo Scientific designed the family of LevelPRO measurement systems to provide
reliable, accurate level measurements for a wide variety of challenging applications. The
level detector, which mounts to the outside of the process vessel never contacts the
process material and can measure the process level in any vessel.
Each detector can convert the basic level measurement into a variety of output values
as appropriate for specific applications.
The system consists of up to three basic elements: the source head, which contains the
radioisotope source; the detector, which converts the incident radiation to a useable
electronic signal; and the integrated (LevelPRO) or optional remote (LevelPRO-T)
transmitter.
The radioisotope source emits gamma radiation, which passes through the vessel wall
and corresponds to the amount of radiation arriving at the detector. The detector then
measures the level of arriving radiation to determine the level of the process material.
The amount of radiation that reaches the detector varies inversely with the level of the
process material.
Figure 1-1. LevelPRO Measurement System

Product Overview
Function
Function
Source A Cesium (Cs-137) radioisotope source is used for most applications, and a Cobalt
(Co-60) source is available for applications requiring a higher energy source. The
radioisotope is bound in ceramic pellets and doubly encapsulated in a pair of sealed
stainless steel containers. The resulting source capsule is highly resistant to vibration
and mechanical shock.
The source capsule is further enclosed in the source head, a lead-filled, welded steel
housing. A shaped opening in the lead shielding directs the gamma radiation beam
through the process material towards the detector. Outside of the beam path, the
energy escaping the source head is very low and well within prescribed limits. Closing
the source shutter allows the beam to be turned off (the shutter blocks the radiation)
during installation or servicing of the detector. All source housings meet or exceed the
safety requirements of the U.S. Nuclear Regulatory Commission (NRC) and
Agreement State regulations. Refer to the gamma radiation safety guide (P/N 717904).
Detector-
Transmitter
The transmitter function in the LevelPRO system is incorporated into the detector
housing to create an integrated system, while in the LevelPRO-T system the
transmitter is a separate enclosure.
The LevelPRO measurement system uses a PVT scintillation detector to measure the
radiation reaching the detector from the source. The detector consists of a PVT
scintillator and a photomultiplier tube with the associated electronics. When gamma
radiation strikes the scintillation material, small flashes of light are emitted. As the level
of the process material increases, more gamma radiation is attenuated by the process
material, which allows fewer gamma rays to reach the detector and generates fewer
light pulses. The photomultiplier tube and associated detector electronics convert the
light pulses into electrical pulses that are processed by electronics in the detector of the
integrated unit or transmitter of the remote unit to determine the process material level
and related measurement values.
Communications &
Measurement
Display
Communication with the detector is via the RS485 and RS232 serial ports, USB, or
Ethernet from a PC running EZ Cal II software. Once the detector is set up, the
primary measurement (level) can be viewed on the display and on the EZ Cal II
software.
Display Background The display on the LevelPRO units provides measurement data to the user.
