 Flow meters provide a simple and effective way of measuring the flow of liquids such as water, oil, or milk through a pipe. The meter can measure any fluid that is ultrasonically conductive and has a reasonably well formed flow. Ultrasonic transceivers allow the meter to be completely operated and installed from the exterior of the pipe, avoiding contact with the liquid. For portable flow-meter applications, National offers a variety of low-power consumption and small-footprint power management parts, to allow this device to last a whole day out in the field. National also offers a variety of data conversion and thermal management products. Component Highlights * Buck switching regulators - high-efficiency SIMPLE SWITCHER® converters and synchronous controllers are cost-effective, reliable, power-saving solutions. * White LED drivers - efficient, low noise, and simple to drive, these devices produce brightness matching and color uniformity in chip-scale packaging. * Operational amplifiers - Rail-to-rail input and output amplifiers maximize the signal range. 1 Amp LM6154 LM8261 LM8262  LMV7219 LMV7235 LMV7239 3 LED Driver LM2704 LM2705 LM2750 4 Thermal Management LM40CIMT LM40CIMTX LM41CIMT 5 DC / DC Converter LM2760 LM2787 LM3519 6 Supervisory LM3700 LM3701 LM3702 7 LDO LM2936 LM9076 LP2966 |
