The Mettler Toledo GPro® 500 Series of 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

The 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

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

Dual 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

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

LIDAR, Non-contact Level Transmitter for Fast and Accurate Measurement

Jogler LLT-1000

Lidar (LIDAR, LiDAR) is a surveying technique that measures distance to a destination by illuminating the target with laser light and using a sensor to measure the reflected light. Differences in laser return times and wavelengths can then be used to determine distance and area. The name lidar was initially a portmanteau of light and radar, now used as an acronym for light detection and ranging. Lidar uses ultraviolet, visible, or near infrared light to sense and image objects.

Jogler's Lidar Level Transmitter LLT-1000 is a laser-based non-contact instrument that measures the level of silos, tanks, hoppers, chutes and bunkers. The LLT-1000 uses time-of-flight laser technology to measure distance. This principle of quick and accurate measurement provides many benefits over other level measurement techniques.

Inline Dissolved Oxygen Sensor Designed for Breweries

InPro6970i for brewing

Oxygen in beer bottles or cans is bad. It affects the flavor and shortens shelf life, so breweries do their best to prevent oxygen getting into beer at the filling line. The Mettler Toledo Process Analytics InPro6970i is an inline dissolved oxygen sensor designed specifically for the needs of the brewery industry. It can measure oxygen in beer at levels of only a few parts per billion.

The sensor is inserted in the pipe at the start of the filling line, and provides real-time measurements on the oxygen content of the beer. If the oxygen level is too high, the flow of beer is stopped to prevent the out of specification product continuing down the line.

Unlike most dissolved oxygen sensors available, the InPro6970i uses a clever optical technique for measuring oxygen. At the tip of the sensor there's a layer of molecules that absorb and emit light. These molecules are sensitive to oxygen which alters how the molecules behave. The greater the quantity of oxygen, the greater the changes in their behavior. The sensor very accurately measures these changes and sends the signal to the transmitter. This technique is extremely fast and accurate at measuring changes in beer oxygen level, which is why it is favored by breweries. But that is not the only requirement breweries demand. Sensors must be rugged, easy to use, and simple to maintain.The InPro6970i scores highly in all these areas. The sensor's stainless steel body is extremely robust, the unit is easily and quickly installed, and the only maintenance required is the periodic exchange of the oxygen sensitive element, the OptoCap. Intelligent Sensor Management, or ISM, is a feature of the InPro6970i that offers significant benefits to breweries. The sensor can be calibrated in a convenient location such as a lab. Upon connection to the transmitter, the system is ready to measure in only a few seconds, so measurement point down time is very short. The dynamic lifetime indicator uses sophisticated algorithms to calculate the remaining life of the sensor, breweries therefore have confidence that the sensor won't fail unexpectedly.
