  • Why A Little Knowledge About Sensors Can Be A Dangerous Thing
    Why A Little Knowledge About Sensors Can Be A Dangerous Thing

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

    Solving A Taste and Odor Problem Step By Step (Article)

    The City of Alliance Ohio’s water system has experienced annual Taste and Odor (T&O) events since the mid 1950’s, when the first of two reservoirs, Deer Creek Reservoir, was placed into service. Nutrient contaminants, in particular phosphorous, in the watershed accumulate in the reservoirs causing algal blooms.

  • Versatility Of Thermal Mass Flow Meters
    Versatility Of Thermal Mass Flow Meters

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

    Making Accurate pH Measurements

    Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.

WATER INSTRUMENTATION

 

 

Process instruments are used widely in water and wastewater treatment plants to monitor the effluent quality. However, their applications are not limited to monitoring effluent quality. These water and wastewater quality monitoring devices can be applied throughout the network of collection, treatment, and disposal

Instrumentation can give guarantee of proficient treatment processes of water quality parameters such as turbidity, pH, ORP, conductivity and dissolved oxygen.  Instrumentation is done in the following aspects.

  • Flow measurement
  • Stage /Level measurement
  • Physical and chemical water quality measurement
  • Biological water quality measurement
  • Water sediment and biota samplers
  • Data storage and management

 

Measurement Techniques include, Gravimetric analysis or, simply, weighing, Colorimetry or spectrophotometry, Titration, and Mass Spectrometry:

 

Platforms on which instrumentation can be carried out include

  • Stationary vertical profilers – Used for in situ sampling.
  • Flow-through systems -Most research ships have built-in flow-through systems that constantly circulate water collected a few meters from the surface.
  • Towed vehicles- towed vehicle such a system is able to provide a continuous series of data points for remote sensing applications where transect lines can follow the flight paths of a remote sensor.
  • Moored platforms - These stationary, or Eulerian, platforms offer data streams synoptically that match with satellite-based imagers.
  • Automated underwater vehicles - Autonomous Underwater Vehicles (AUVs) afford their own propulsion there by allowing high-resolution sampling of the ocean’s interior in multiple directions.

Some of the instruments used in water management are:

  • Pressure Transmitters
  • General Service Gauges
  • Pressure Regulators
  • Digital Panel Meters
  • Process Calibrators
  • Thermometers
  • Differential Pressure Gauge and Switches
  • Multi-Point Thermocouple Displays
  • HART Calibrator/Communicator
