  • Flow Switches for Oil/Gas Refinery Water Treatment
    , etc., that can be used in refinery wastewater treatment. They all, however, have one thing in common: liquid flow switches are necessary to monitor and control the flow of water and chemical additives throughout the wastewater treatment system. Flow switches are used at multiple points in water
  • Flow Switches & Flow Meters: Affordable Innovation in ifm's Flow Technologies
    Affordable innovation: sounds like an oxymoron, but for ifm engineers, it's a guiding design philosophy. Ten years ago, the cost difference between a mechanical flow switch and an ifm sensor was substantial. Today, ifm's sensor prices have reduced considerably to the point where they can easily
  • Flow Switches for Refinery Water/Wastewater Control
    To ensure quality production of petroleum-based products in oil refineries, including gasoline, diesel, kerosene, heating oil, and byproducts for plastics and a variety of lubricants, operators must establish reliable water monitoring and treatment. There are three refinery process areas that
  • Liquiphant M Replaces Flow Switch for Water Detection
  • Sensing Air Flow with the PIC16C781
    Programmable Switch Mode Controllers (PSMC) are not just for switching power supplies. This technical brief describes how to use the PIC16C781 PSMC in combination with the Integrated Operational Amplifier, Digital-to-Analog Converter (DAC), and gated timer to construct a thermally operated air flow
  • Lubricating electrical switches
    current flow. Nonnoble contact surfaces and switches made of dissimilar metals are especially susceptible to moisture, oxygen, and aggressive gases. Even noble-metal plating is at risk if it's worn or porous. Lubricants also minimize wear, especially on sliding electrical contacts which see repetitive
  • S2079: Drivers for GaAs FET Switches and Digital Attenuators
    is the n-channel depletion mode device, which has low source-to-drain resistance in the absence of a gate bias, and allows a current IDSS to flow. With the application of a negative gate bias voltage, the electric field below the gate causes the conduction channel to narrow, increasing the source
  • Traditional solenoid valves are simple to install but may not be the right solution for long term reliability or high flow applications
    Replacing a solenoid valve with a DynaMatic electric ball valve...Why and how?. Solenoid valves are typically easy to install and are used in applications utilizing pressure, flow, temperature and level switches. They can also be controlled by PLC units that only output a single control signal
