No More Purge Gas Required for New Tunable Diode Lasers for Combustion Processes


A new generation of TDLs not only offers exceptional fuel costs savings, but eliminates the need for process side purge gas.


Refineries, petrochemical, fertilizer and power plants worldwide have large numbers of combustion processes in operation, from process heaters and fired heaters to package boilers and large steam turbines. Whenever a process fluid needs to be heated as part of a chemical reaction, or there is a requirement for steam generation, there will be a combustion process at its heart.

This paper presents a review of the general anatomy of a typical combustion process; describing each zone and its function, before discussing some of the challenges of combustion measurement and how modern TDL analyzers such as METTLER TOLEDO’s GPro 500 and its range of process adaptions offer many advantages over typical combustion analysis technologies.

Proper Installation of BriskHeat XtremeFLEX Heating Tape


BriskHeat XtremeFlex heating tape is very versatile due to its superior flexibility. Although it is versatile, there can still be failures in hotspots if it's not properly installed. The purpose of this short video is to help you avoid failures and hot spots, and to help you install your heating tape for optimal performance.

Before you get started there's a few things that you should keep in mind:
  • Make sure you have these tools prior to installing the heating tape - Gloves, Heating Tape, Heat Conductive Putty, Scissors, Fiberglass Tape.
  • Be sure that the surface that you're applying the heat tape to is clean, dry, and free of burrs, oils, debris or sharp edges. 
  • Ensure that you don't overlap the heating tape onto itself leave at least an eighth of inch gap between each wrap.
You also want to ensure complete surface contact between the heating tape and the surface. Air gaps can cause hotspots which can result in premature failures to the heating tape. Use our heat conductive putty to bridge any gaps between the heating tape and the surface.  When working with heat conductive putty, wear proper personal protective equipment. Place a fair amount of putty where the transitions meet so that there will not be any air gaps when installing. With many heating tapes you will need a temperature controller device, so contact your BriskHeat Representative for assistance.

To make sure that the heat tape stays in place use briskets high-temperature fiberglass adhesive tape or high-temperature aluminum adhesive tape because it will not damage the heating tape and it can withstand the high temperature that the heating tape produces.  Use insulation on BriskHeat heating products in order to avoid heat loss.

The Mettler Toledo GPro® 500 Series of Tunable Diode Lasers

Tunable Diode Lasers


Tunable Diode Lasers (TDLs) use a measurement technology called absorption spectroscopy: they output a beam of laser light at the same frequency that the gas to be measured absorbs light. The TDL analyzes the light after it has passed through the gas stream and calculates the quantity of the target gas in the stream. The use of TDL sensors is becoming more and more common in industrial processes.

Mettler Toledo manufactures the GPro® 500 TDL Series of Tunable Diode Laser designed for the toughest gas measurements. These analyzers are known to handle some of the most demanding process applications, particularly where accuracy and fast response is crucial.

Using a modular design, the GPro® 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂).

GPro® 500 Tunable Diode Laser - Eliminate Alignment

Most TDLs are comprised of two parts: the laser source unit and a receiving/analyzing unit. These parts must be installed directly opposite each other, which is not always easy and misaligned can often occur. METTLER TOLEDO's GPro® 500 Series solves this by combining both parts in a single unit. A probe attached to the GPro® sensor protrudes into the gas stream. A three-sided mirror at the end of the probe directs the beam back through the probe to the receiver, so alignment is always perfect.

GPro® 500 Tunable Diode Laser - Minimal Maintenance

GPro® 500The GPro® does not require "maintenance intensive" extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.

Brewers, Make Oxygen More Your Friend, and Less Your Enemy. Check Out the Mettler Toledo InTap™ Portable Optical DO analyzer

InTap™ DO analyzer
InTap™ DO Analyzer 

Brewers have a complicated relationship with oxygen. 


At times oxygen is your friend. It's needed for barley germination. It's needed to synthesize fatty acids and sterols in yeast. And it improves colloidal stability. 

Oxygen is also one of the the brewers worst enemies. It has a significant effect on color. It lowers the  rate of wort separation. It can cause undesirable flavors. And is causes haze and makes finished beer stale.

By the way, we're talking about the dissolved oxygen (DO) in solution here. Not the external oxygen the water, wort, or beer tank headspace.

Fortunately Mettler Toledo provides instrumentation to assist brewers in they management of oxygen. Their InTap™ DO analyzer with optical technology, is both a portable measurement tool and a convenient calibration instrument. It facilitates measurement and calibration procedures in both process and laboratory settings, and reduces the risk of operator error.

The InTap™ portable oDO analyzer is a portable measurement device for dissolved oxygen
measurement and for calibration and data logging of optical dissolved oxygen ISM® sensors
(InPro® 6970i) installed in the process. The InTap™ and the sensors communicate via Bluetooth.

Measurement point tracking in the InTap™ portable dissolved oxygen meter allows operators to easily connect stored measurement data to different locations in production, making it easy to maintain records point-by-point for traceability and documentation purposes.

Reliable optical dissolved oxygen (DO) sensor technology is also available in the InTap™ portable meter for spot check and reference measurements. With Blue- tooth communication, hassle-free calibration of in-line DO sensors is done quickly and easily.

Jogler Dual Chamber Level System

Jogler Dual Chamber Level SystemDual chamber systems are often ideal for magnetic level gauges. The compact design eliminates the need for coaxial probes. Dual chamber systems also allow for multiple redundant technologies, including guided wave radars, capacitance level transmitters, and tuning fork level switches.

Advantages of Dual Chambers

  • Cuts out need for coaxial probes
  • A single probe can be easily removed from the chamber for maintenance and cleaning
  • Putting a Guided Wave Radar and a float in a single chamber requires larger pipe and flange sizes and a baffled plate between the float and the GWR coaxial probe

Disadvantages of a Single Chamber System

    Jogler Dual Chamber Level System
  • A magnetic field orientation not optimal for instrument installation
  • Radar interference due to the baffled plate
  • Float obstruction due to an extra wall in the chamber
  • Mandatory use of coaxial probe shields which are susceptible to blockage and fouling leading to
  • incorrect measurements
  • Increased cost and weight of the system
  • Remote mounting of GWR electronics when top connections to the system are necessary
