Comments Off on Transmitter for gas density, temperature, pressure and humidity of SF6 gas
The model GDHT-20 transmitter is a multi-sensor system with digital output for the measurement parameters of pressure, temperature and humidity. Based on these measured values, the condition-related data can be determined.
In order to prevent system failures in switchgear and, with that, network outages, the permanent monitoring of the gas density and moisture content is essential.
The GDHT-20 transmitter calculates the current gas density from the pressure and temperature using a complex virial equation in the transmitter’s powerful microprocessor. Pressure changes resulting from thermal effects will be compensated by this and will not affect the output value.
In addition, the GDHT-20 transmitter delivers humidity or dew point information online, which enables monitoring within the terms of Cigre guidelines and IEC Standards.
Due to its high long-term stability, the transmitter is maintenance-free and requires no recalibration. Through the hermetically sealed weld seam and a measuring cell design without sealing elements, the permanent sealing of the measuring cell is ensured.
The EMC characteristics fulfill the IEC 61000-4-2 through to IEC 61000-4-6 standards and guarantee an interference-free data output.
Permanent monitoring of the relevant gas condition parameters in closed tanks
For indoor and outdoor SF6 gas-insulated equipment
High-accuracy sensor technology
MODBUS® output protocol via RS0485 interface
Ingress protection IP65
Very good long-term stability and EMC characteristics

Comments Off on Lower Total Cost of Ownership with LESER Safety Relief Valves
Valve maintenance and repair play a significant role in the total cost of ownership through out the life cycle of a safety relief valve. LESER has the lowest total cost of ownership due to its competitive initial valve pricing combined with very attractive parts pricing. LESER’s superior valve design leads to better operation; in turn leading to less parts replacement, which significantly impacts the total cost of ownership of the valve.
API 526 Series are approximately half the cost of competitors’, providing significant cost savings to our customers over the life of the valves.

Comments Off on Donaldson Co. jumps into Beverage Filtration with LifeTec
It took the Donaldson Co. two years, 40 scientists and millions to build a better mouse trap – or a microbe trap, to be exact — for the beverage and yogurt manufacturers.
Donaldson, the filtration giant, known for devices that purify air, steam and gases inside factories, recently threw it’s filtration expertise into the world of consumable liquids for the first time.
The result is LifeTec, an ultrafiltration cartridge that captures microbes, bacteria and particles from beverages. Officials cut the ribbon on a new manufacturing plant in Haan, Germany, earlier this month that will make the product and said it could result in big changes in the market.
LifeTec liquid filters capture dust, bacteria and the cryptosporidium and giardia parasites that could sicken humans and cripple most food makers if the microscopic pests accidentally squirmed into a product. The LifeTec cartridge is designed for firms that must filter and sterilize water and other liquids to make mineral water, soda, cheese, yogurt, wine, beer and other beverage products.
LifeTec comes in various lengths starting at 10 inches and surpassing 40 inches. Each cartridge should last one to three months before needing changing, depending on beverage-factory conditions. While officially launched this month during the plant opening in Germany, LifeTec soon faces a whirlwind of global introductions at trade fairs, including the world’s largest industrial trade show, the Hannover Fair in Germany.
In the U.S., LifeTec will make its debut at the Northwest Food and Beverage Manufacturers Expo in Oregon in January and the Process Expo in Chicago in September 2017.
Comments Off on Thermal Mass Flow Measurement an Effective Solution for Liquid Leachate
Thermal Instrument manufactures a mass flow meter that can accurately and dependably measure the leachate flow at landfill operations. Thermal Instrument has been measuring liquids with mass flow meter technology for more than 50 years and offer a tested solution for the measurement of leachate flow.
Leachate is the liquid that naturally drains down through the landfill waste levels collecting any dissolved or suspended materials as it passes through the ground. It is a naturally occurring event that must be accounted for, captured, and treated as it is a pollutant. It is the responsibility of the landfill operator to insure that this liquid makes it to a safe holding area prior to being treated and discharged.
Advantages of using a Thermal Instrument Insertion Probe Flow Meter
Rugged Construction – 316SS with available protective coating
Easy Installation – 3/4″ MNPT Packing Gland
Installed Back up Sensors for inherent redundancy
Sensors are internal and never come into direct contact with passing fluid
Flow and Total Flow Monitored
4-20mA output to data recorders, PLC’s, etc.
High Turndown Accuracy – 100:1
Easy to clean and maintain

Comments Off on Level Gauges that meet Compact Skid Design Requirements
Building a specialized skid with all the necessary equipment and measuring instruments required thoughtful, compact design. Skids often have to fit in very limited space in a processing facility, meaning you have to fit in as much function as possible in the allotted space.
Level gauges with an inverted designed offer space-saving features. In fact, Wika has helped a number of OEM skid builders come up with new space-saving skid designs that leverage this type of level gauge, which is fitted with multivariable transmitters and alarm switches that send process data.
Comments Off on Thermal Mass Flow Meters Measuring Carbon Dioxide (CO2)
Carbon Dioxide is generally not produced, rather is derived as a by-product from other processes such as the manufacturing of ammonia, fertilizers, power generation and other naturally occurring events. The gas is then captured, cleaned, and bottled to be used in a wide variety of industrial processes. These processes require measurement and that measurement can be performed by a Thermal Instrument Mass Flow Meter.
The use of Carbon Dioxide Gas (CO2) and then how it is captured in industrial applications has been scrutinized over these past few years, with all the discussion of greenhouse gases. Thermal Instrument Mass Flow Meters have been used to measure the CO2 that is being used, and then re-captured in order to minimize GHG’s being released to the atmosphere.
Thermal Instruments Model #600-9 has a variety of process connections and the ability to be placed in line sizes as small as 1/4″, has been reliable measurement instrument for our customers that are managing their C02 usage. The in-line unit has negligible pressure drop (application dependent), high repeatability, and the accuracy needed to manage this process for many years. Our mass flow meters have been utilized in beverage manufacturing, power generation, and other manufacturing operations to name a few.
The Thermal Instrument Mass Flow Meter is available in standard 316 Stainless Steel for your industrial applications, and in a Sanitary (Model #600-9SAN) design that meets the requirements of Food, Beverage, and Pharmaceutical manufacturers if necessary.
Common Carbon Dioxide applications for our mass flow meter are:
Measuring the CO2 by-product at coal fired power plants for recovery, or to be sold as an additional product
Measuring CO2 in the carbonization and bottling process in the beverage industry
Food Processing for freezing or chilling, and packaging operations
Injecting CO2 into the ground during hydraulic fracturing near or at the site of oil wells to draw out every last trace of crude oil
As a raw material in the chemical industry
Used to enhance algae production for nutritional and health sciences
Cleaning the circuitry during the semiconductor manufacturing process removing impurities in place of chemical solvents
Comments Off on Sanitary Plug Valves for Low Temp Dairy, Beverage & CIP Lines
With minimal pressure drop Top Line’s 2 and 3-way sanitary plug valves are an excellent choice for low pressure low temperature dairy, beverage and CIP lines.
The valve is COP only (clean-out-of-place) and designed for 25psig at 100°F for use with non-hazardous products.
The valve comes in 304 or 316L stainless steel with an option of two different plug styles – silicone rubber or stainless steel.
Plug valves feature a tapered core assembly held in place with a wing nut and washer on the bottom. This allows for easy disassembly and cleaning while eliminating crevices which can lead to contamination. The valve and plug both have matching identification numbers on them so they don’t get mixed with other plug valves.
