  • Leak Detection in Pipelines
    Hoffer Flow Controls continues to supply many "insertion" type turbine flowmeters to the petroleum pipeline industry. This type of meter is commonly used for leak detection and not custody transfer. Custody transfer applications are addressed with "in-line" axial flowmeters such as the Hoffer API
  • Low Cost High Quality SERVO/FILL® Liquid Filling Machines
    Oden Corporation designs, manufactures and markets electronically controlled positive displacement liquid filling, dosing and metering equipment, configured as benchtop liquid fillers, semi-automatic liquid filling machines, and fully automatic liquid filling systems, and continuous stream digital
  • Circuit Ideas: Setting Up a Low-Power Transceiver
    in receive mode. Current consumption in transmit mode depends on output power but is less than 30 mA at 10 dBm. Typical applications include home automation, wireless security systems, meter reading, and toys. The CC1000 is generally intended for use over short ranges. It operates at 315, 433, 868
  • Environmental Noise Control Trends in Instrumentation
    ], [2]. Many cities, regions and countries have established limits on the amount of noise that the population should be subjected to. Integrating Sound Level Meter technologies and microphone technologies have evolved over the years, and have reached a point where precise reliable instruments have
  • High-five to high-side current sensing
    through the meter. The technique was called high-side current sensing. However, high-side shunts require isolation in modern electronic control systems because of their direct connection to the high-side voltage rail. Current transformers perform this service in ac power systems. But the size and cost
  • Candidates for exploring Mars
    through them. The sunlight will let the spectrometer analyze the particles' chemical compositions and concentrations. In addition to spectro-meter data it collects, Ares will also send back to Earth a stream of measurements on parameters such as air pressure and density, temperature, and wind speed
  • Medical Device Link .
    this concern, manufacturers are expanding their efforts to make glucose meters that take continuous measurements. Rather than a single measurement, a busier type of monitor produces a continuous stream of glucose readings. Some continuous monitors rely on under-the-skin sensors; others do their sensing outside
  • Advanced Oxidation Ditch Performance (.pdf)
    , respectively, of design capacity in recent years. The Oxford WWTP discharges to a water quality limited stream, and therefore it has relatively stringent NPDES effluent requirements. The monthly average effluent limits are as follows: BOD5. =. 10 mg/l. TSS. =. 30 mg/l. Ammonia-N. =. 2 mg/l
