The XLG furnaces are multi-purpose gas fired box furnaces. They are highly uniform in temperature and feature accurate digital controls and multiple medium or high velocity Eclipse "Thermjet" proportionally controlled burners with an independent combustion blower. The XLG furnaces can be rated as high as 2400°F (1315ºC) although typical rating is 2000ºF (1093ºC). Connected gas pressure can be as low as 1 PSI. Firing with gas can be more economical than firing with electricity. In addition, the circulation of the hot gases, especially with multiple medium velocity burners, promotes good temperature uniformity without the use of high temperature fans. The burners can be adjusted to run lean to provide a slightly reducing atmosphere (although this can not be precisely controlled.) These furnaces are excellent for ceramics processing and most metallurgical work where precise atmosphere control is not required. Systems can be designed with excess air for high uniformity at low temperatures.

FEATURES

ECLIPSE THERMJET VELOCITY BURNERS
The furnace is heated with three or more Thermjet medium or high velocity burners. These typically fire over the load with burner placement balanced to maximize circulation of the combustion products. In some large units they may be configured to fire over and under the load. These are sized for the proper BTU requirements and fuel type of your furnace. In addition the choice of high or medium velocity is an engineering choice dependent on load configuration and furnace size. The burners feature low N OX emissions, integral gas and air orifice plates (for precise gas and air balancing), high velocity for good temperature uniformity in the furnace, and excellent turn down ratio for a wide range of control. The burners are direct ignition which eliminates the need for a bypass pilot.

FM GAS TRAIN
The gas system includes two hydraulic-mechanical shut off valves, manual shut off valve, pressure regulator, and pressure gauges. Each burner has gas and air adjustment and shut off valves. A proportionating valve, controlled by the combustion air, maintains stoichiometric air/gas ratio. Systems can be designed to fire with excess air for high uniformity at low temperatures. (IRI rated gas train is optional.)

COMBUSTION AIR BLOWER SYSTEM
Combustion air is provided by a centrifugal combustion blower. A pressure gauge and air pressure switch monitor performance. Each burner has separate orifice plates and butterfly valves for precise balancing of air flow. The control of firing rate is done with a motorized butterfly valve which controls the amount of combustion air relative to a 4-20mA signal from the temperature control.

ELECTRONIC FLAME SAFETY SYSTEM, SPARK IGNITOR AND PURGE TIMER
Each burner is ignited with a spark plug automatically actuated from the Eclipse Multi-Flame Series 6000 flame safety system. UV (Ultra Violet) sensors monitor each burner. Before ignition the system goes through a timed purge with the combustion air. Safety interlocks include a combustion air pressure switch and gas high/low pressure switch. The Eclipse Multi-Flame 6000 flame monitoring system keeps the operator apprised of the status of the burners. It includes running time along with voltage signal t o each UV sensor. It will alert the operator of any problem with the burners, air flow or gas pressure and will provide "first out" information to actually pinpoint a problem. The operator only needs to press the RESET key to start the burner firing sequence.

HIGH TEMPERATURE UNIFORMITY
The furnace is +/-15F (+/-7C) above 1200F (650C) within the working dimensions. High uniformity at lower temperatures can be achieved with excess air.

EFFICIENT CERAMIC FIBER INSULATION
The sides, back, door and top surfaces are typically insulated with 2300F ceramic fiber modules, 8" thick, 10 LB density, although this is easily modified for different temperature ranges and applications. No asbestos is used. The bottom is insulated with a combination of castable and firebrick. Loads can be directly placed on this strong bottom. Optional castable piers, and ceramic, silicon carbide, serpentine or flat alloy hearth plates are available.

HEAVY DUTY CASE WITH INTEGRAL STAND
The furnace case is constructed of heavy gauge steel with structural stiffeners, lifting rings and leveling bolts. The case is primed with a high temperature (800F) silicone based paint and finished with heat resistant enamel.

COUNTERBALANCED PNEUMATIC VERTICAL DOOR
The standard furnace door has a counterbalanced vertical door with a pneumatic opener and hand or foot operated valve. Double pivoted horizontal doors are optional (standard on 6 and 8 foot high models.)

DIGITAL PID CONTROL SYSTEM WITH HIGH LIMIT
The standard control is a Honeywell UDC 2300 digital PID 3 mode tuning control. A Honeywell UDC 2300 high limit control is also included. All fuses and controls are located in a NEMA 12 panel. The thermocouple is dual Type K with an Inconel protection tube. A limit switch turns down the burners when the door is opened. Control voltage is 120 volts. The furnace is fully fused. Single point power connection.

MEETS NEC, OSHA AND FM CODES
The wiring of the furnace meets the National Electrical Code. The combustion system meets FM standards. IRI standards are available. Furnace meets all OSHA codes in effect at manufacture. Furnace drawings can be submitted to FM or IRI for approval.

FACTORY TESTING, START UP AND INSTRUCTIONS
The furnace is completely tested in our factory up to maximum temperature. A very complete instruction manual is included. A factory technician will start up furnace in your factory and make all adjustments on site.

ONE YEAR WARRANTY

Precise Flow Measurement In Wet Gas With Self-Conditioning Flow Meter

Coal Bed Methane, Oil/Gas, Chemical, Food/Beverage, Water/Waste

Process and plant engineers in rugged industries who must frequently measure various hydrocarbon-based gases with wet particulates will find the Wafer-Cone^® Flow Meter from McCrometer features a unique self-conditioning design that achieves superior flow measurement accuracy in small line sizes.

The Wafer-Cone Flow Meter is ideal for industrial process and plant applications, including coal-bed methane gas extraction. The process of extracting this gas typically includes water within the gas seam in the coal bed, which results in a wet gas with tiny water particulates that are difficult to measure accurately.

McCrometer's innovative Wafer-Cone Flow Meter solves this problem. It relies on differential pressure technology with built-in flow conditioning and achieves flow measurement accuracy of ±1% or better, with a repeatability of ±0.1% in gas, liquid or steam applications, including coal-bed methane recovery.

The Wafer-Cone Flow Meter operates over a turndown range of 10:1. It is designed for service in small process line sizes from 0.5 to 6 inches, which makes it ideal for a wide range of other industrial applications, such as conventional natural gas wells, chemical refining, as well as industrial waste treatment and even landfill applications where biogas is frequently present and may be utilized for electric power co-generation purposes.

With the ability to self-condition flow, the Wafer-Cone Flow Meter is a real space-saver too. It eliminates the need for extensive up/down stream straight pipe runs required by other DP technologies, such as orifice plates and tubes. It can be installed virtually anywhere in a piping system or be easily retrofit into an existing piping layout, resulting in significant installation flexibility and in new installation initial cost savings.

Unlike traditional DP instruments such as orifice plates and tubes, the Wafer-Cone Flow Meter's design is inherently more accurate because the flow conditioning function is built-into the basic flow sensor design. The Wafer-Cone conditions fluid flow to provide a stable flow profile with high signal stability that increases accuracy. The flow sensor's design features a centrally-located cone inside a tube. The cone interacts with the fluid flow and reshapes the velocity profile to create a lower pressure region immediately downstream.

The pressure difference, which is exhibited between the static line pressure and the low pressure created downstream of the cone, is measured via two pressure sensing taps. One tap is placed slightly upstream of the cone and the other is located downstream of the cone. The pressure difference can then be incorporated into a derivation of the Bernoulli equation to determine the fluid flow rate.

The cone's central position in the line optimizes the velocity of the liquid flow at the point of measurement. It forms very short vortices as the flow passes the cone. These short vortices create a low amplitude, high frequency signal for excellent signal stability. The result is a highly stable flow profile that is repeatable for continuous accurate measurement. All of this is possible with a minimal straight pipe run of 0 to 3 diameters upstream and 0 to 1 diameters downstream from the flow meter.

The field-proven Wafer-Cone is an easy to install space-saving flow meter that requires almost no maintenance. Wafer-Cone's low maintenance combined with its long life results in lower total installation and life-cycle costs than many other flow meters.

Velocity XPT is more than a next-generation Purge and Trap system, it's a revolutionary leap in technology. Advancements in Velocity XPT ensure the highest throughput with the least amount of downtime. From cutting sample cycle time nearly in half, to built-in intelligent diagnostics, Velocity XPT is the most productive Purge and Trap available today.

With the Velocity XPT, you increase the sample throughput up to 100%. This nearly double sample throughput and increases the profitability of your VOC lab without the cost of an additional GC system. Patent-pending Accelerated Purge and Trap technology lets you independently control the flow rate during all modes, greatly reducing dry purge and bake times. Velocity XPT also provides a 25% reduction in trap cool down time after bake mode.

Forward Focusing Chamber:
This patent-pending technology provides the highest resolution chromatography and superior peak shape for early eluting gases. By placing an expansion chamber after the trap during the desorption modes, analytes are focused into a tight band. When analytes are tightly focused prior to desorption into the GC, dramatic improvements in chromatography resolution are evident. The FFC also efficiently desorbs which greatly reduces carryover from run to run.

Exceptional Inertness:
Silcosteel tubing and Silcosteel-treated fittings throughout the sample pathway prevent loss of active, polar, and high-boiling compounds, and also resists corrosion.

With the simple setup and accurate control, you save time by entering all parameters electronically with Electronic Flow Control where flow and pressure parameters remain precisely the same and are constantly monitored for accurate and reproducible results.

Automatic Leak Check, Electronic Pressure Monitor:
With intelligent diagnostics, Velocity XPT quickly and simply checks itself for leaks. If a leak is detected, system diagnostics help you isolate and pinpoint leaks. The Electronic Pressure Monitor uses a pre-set over pressure limit to identify potential pressure build ups and will shut itself down before damage can occur.

The Guardian Foam Sensor option is a set of built-in photodiode-based sensors. If foam or liquid is detected at the top of the glassware, purge gas shuts down, the vent valve closes, and the sample drains. Guardian can be configured to automatically add an anti-foaming agent to the sample, allowing purge to continue and without re-running the sample.

VOC TekLink software comes standard and gives you the versatility needed to control both Velocity XPT and Tekmar autosamplers. The built-in Internet-based status alert system ensures that you will always know the status of your purge and trap system, even when you're not in the laboratory. The new Method Development Wizard generates an optimized method for traditional EPA purge and trap protocols based on your method requirements.

Velocity XPT comes with a free firmware upgrade for your Tekmar vial autosamplers (AQUATek 70 and SOLATek 72) and ensures that your autosampler fully leverages new features like productivity-boosting accelerated purge and trap cycle time. If an error occurs, run the TekLink Benchmark Test to automatically verify all critical electrical and mechanical components and quickly isolate problems and troubleshoot. Other enhancements include a new modular valve manifold system and power output LEDs that eliminate the need to use a voltmeter.

Proportional Velocity Flow Meters, PV Flow Meters from The Oilgear Company. A 'PV Meter' is a flow meter that will handle problem fluids that damage other meters. The Oilgear PV Meter (Proportional Velocity) will pass sand, grit, stones (up to 0.25" diameter in our smallest meter), bits of wood or rubber, and suspensions that could stop and damage other meters. There are no close clearances, no rotating seals, and no stuffing boxes. This simple design provides little that can go wrong. If something should malfunction, there is a simple field fix without having to remove the meter from the line.

Please use the links to the right to view additional specifications, ask a question or to request a quotation.

Here's how it works:

The Oilgear PV Meter looks like a short section of pipe, with a rotor and rotor chamber offset and perpendicular to the flow axis. The flow stream, combining the effects of a Pelton wheel and a centrifugal flow turbine drives the rotor. This combination gives a rotor speed PROPORTIONAL to the flow VELOCITY passing through the rotor chamber, over a wide range of flow rates. The combination gives the same performance and small size of a typical axial flow turbine meter, but with the lower speed and higher torque of a typical positive displacement meter.

Advantages of the PV Meter

• Large Particle Clearance
  Due to the rotor-cage construction, coupled with the offset chamber, large particles (up to 0.5" diameter in the 2" size 20 meters) can pass through the meter body without causing damage.
