  • Measuring TOC in Brine Solutions

    In the chlor-alkali and electrolysis industries, as well as many others, there is a need to analyze for TOC in samples containing high salt concentrations. These samples can range from sea water, which is typically 3% salt, up to brine solutions containing 28% salt. Shimadzu’s TOC-L with the high salt kit (P/N 638-93176-01 for N model & P/N 638-93176-02 for H model) is well suited for ...

  • Safety vs. Environment Protection: Study Discovers Increasing Salt Levels in Lakes

    A recent study published by the US-American National Academy of Sciences revealed an increasing salt amount in form of chloride in rural and urban freshwater lakes around the American continent. The scientists believe, that mainly road salt distributed on icy roadways is to blame. Increasing salt levels threaten eco systems Road de-icing salt is blamed for rising salt levels in ...

  • Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

    The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.  What Denver's New Law Requires  The law ...

  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Process Water Treatment – Challenges and Solutions

    Untitled Document Clean water is needed by chemical-process plants for a wide range of process-related and auxiliary uses. Likewise wide is the range of options available to the ...


  • Research on PWM applied in water turbidity measurement

    In this paper, three common measuring methods for the principles of water turbidity, namely, scattering, transmission and the ratio method are introduced. A method combined with modulation and demodulation techniques based on pulse width modulation (PWM) pulse for turbidity measurement using light intensity modulation is proposed. The experimental system that is, the realizing circuit of ...

  • Pure water pH measurement in low conductivity samples

    Normally, pH measurements are made in water with 1,000 to 10,000 uS/cm conductivity. The conductivity conies from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the solution in ion form, which makes such solutions conducting. With 1,000 uS/cm conductivity of mobile ions pH electrodes have a good circuit and give fast, ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • Cycle chemistry pH measurement

    pH measurement in high purity water has met with variable success. The high resistivity of pure water, the vulnerability to contamination, the variability of reference electrodes and additional temperature effects converge to make tins a particularly challenging measurement. Overcoming these obstacles requires a thorough understanding of the potential problems and their systematic solution. ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • OTT ADC measurement - Germany

    Background As the open pit Cottbus Nord is making use of the water of the ponds in the protected landscape of Lakoma (a village 6 km from Cottbus) the Vattenfall Europe Mining AG (VEM) as owner of the pit was obligated to take compensation measurements. VEM entrusted the engineers of the gerstgraser Ingenieurbüro für Renaturierung (gIR) in Cottbus with the planning of the ...

  • Radar measurement in the North Sea

    Background / Task The NLWKN operates the barrier in the inland waterway of the river Ems. They are working with a dense monitoringnetwork which is required e.g. for the preservation of evidence in case of blocks for the protection against storm tides or if the water depth has to be increased to make the Ems navigable for big vessels coming from the dockyard. After an average a new radar ...

  • Measuring Pressure and Vacuum Correctly

    Pumps and systems are installed, started, operated, and many times, forgotten. When a problem arises, it’s recommended to install a discharge pressure gauge and suction vacuum gauge on the system. These gauges should be installed near the suction inlet and discharge outlet of the pump. These gauges are usually installed properly, recorded, and along with a pump speed measurement can be ...

  • Contact-free indirect measurement

    The non-contact mode of measurement is very interesting for hygienic applications in the food-, pharmaceutical- and cosmetics industry, as well as for industrial applications with thick, adhesive and solid containing liquids. Experience has shown that conventional volumetric flow meters quickly come to their limit, while other measuring procedures are often very complex and/or are not suitable ...

  • USA water challenges are many, but so are the solutions

    Many of the nation's water-supply systems need expensive improvements. And in the West and elsewhere, utilities are focused on finding enough water to meet demand. Although the problems are complex, experts generally agree on some basic solutions. PROTECT WATER SUPPLIES Providing clean drinking water starts at the source - whether it's an underground aquifer, a lake or a ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Reliability assessment of water distribution systems with statistical entropy and other surrogate measures

    There is ever increasing commercial and regulatory pressure to minimise the cost of water distribution networks even as the demand for them keeps on growing. But cost minimizing is only one of the demands placed on network design. Satisfactory networks are required to operate above a minimum level even if they experience failure of components. Reliable hydraulic performance can be achieved if ...
