ABSTRACT Fine-grained water quality data can facilitate the optimized management of water resources, which have become increasingly scarce due to population growth, increased demand for safe sources of water, and environmental pollutions. There is a pressing need for cost-effective, reliable, re-usable, and autonomous water sensing technologies that can provide accurate real-time water quality measurements. In this paper, we present a microwave sensor array with sensing elements operating at different frequencies in the wide frequency band of 1 GHz to 10 GHz. The use of array allows for collecting more information compared with a single sensor system. The sensor array can be fabricated in a cost-effective way through standard printed circuit board (PCB) technology. Here, it is tested with water solutions of various contam- inants and parameter values. The dielectric properties of the water sample with different contaminants and parameter values are measured and provided as well.

  • Level Sensors
    1-800-633-0405 For the latest prices, please check AutomationDirect.com EchoPod/EchoTouch® Reflective Technology™ Ultrasonic Liquid Level Sensors Overview The innovative EchoPod/EchoTouch Reflective Techonolgy ultrasonic liquid level sensors replace other ultrasonic level sensors in condensation applications, as well as float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling media in small, medium and large capacity tanks. Applied in chemical, water and wastewater applications, these general purpose or intrinsically safe non-contact sensors are available with single and multi-function capabilities, including continuous level measurement, switching and control. The standard 4-20 mA output is easily monitored by a PLC or other controller. Models with four relays can be configured for level alarms and/or stand- alone level control such as automatic fill or empty functions using the embedded level controller. PC configuration of all models is simple with WebCal™ software, while the UG06, UG12 and US06 models also offer limited configuration via their pushbuttons and integral display. What is Reflective Technology™? Condensation is the most commonly encountered variable in liquid level applications. Condensation attenuates the acoustic signal of ultrasonic sensors that have a flat horizontal transducer face, weakening their signal strength and signal-to-noise ratio by up to 50%, and substantially reducing their measurement reliability. At the core of Reflective Technology™ is a simple fact: unlike flat horizontal surfaces, significant water droplets cannot adhere to smooth vertical surfaces. By orienting the internal ultrasonic transducer vertically, condensation runs off the transducer face and does not affect sensor performance. The unimpeded transmit and receive signals are redirected to and from the liquid off a 45º reflector, delivering reliable level measurement.

Stochl and Richard L. DeWitt Lewis Research Center SUMMARY In experimental studies of the pressurization and expulsion of liquid hydrogen, temperature-measuring systems are needed to understand the effectiveness of a parti- cular pressurization system. Existing state-of -the-art temperature-measuring systems are considered inadequate to meet the rather stringent design requirements necessary for accuracy and precision in the measurement of ullage gas temperatures. A temperature-measurement technique that uses thermopiles (i. e. , thermocouples in series) as sensors was therefore developed. The results of this development indicate (1) that an instrument rake using measurement stations constructed of thermopiles can measure temperatures to within *l.65' K (for gas temperatures between 20' and 300' K) and (2) that, in addition to their use as temperature sensors, thermopile units can be used as point liquid-level sensors for subcooled liquid during liquid outflow.

Some LM divertor concepts intended for long-pulse operation at >20 MW/m2 incorporate thin (~1 cm), fast-moving (~5 to 10 m/s), free-surface flows. Such systems will require a range of diagnostics to monitor and control the velocity, flow depth, temperature, and impurity concentration of the LM.

These sensors are ideal when vapor, dust, or a foaming surface prevents ultrasonic-wave measurements. LVRD500 Series radar sensors can detect the level under a layer of light dust or airy foam, but if the dust particle size increases, or if the foam or dust gets thick, they will no longer detect the liquid level.

  • Ultrasonic Point Level Sensor
    Product Overview Ultrasonic Point Level Sensor Product Overview The Fluid-Trac® PLS (Point Level Sensor) is a durable, economical control module for reliable limit level control OEM applications. The Fluid-Trac® PLS comes in a compact package that combines a smart point level ultrasonic level sensor, internal temperature compensation, embedded software and three low side output circuit drivers. The Fluid-Trac® PLS control module was designed for versatile external control capability. It can be interfaced to Relays, Switches, Pumps, Valves, Audible Alarms/Buzzers and Flashing Alarms. Listed below are a few of the typical OEM applications: • Single Point Control – Fluid-Trac® PLS can keep a tank from running dry or overflowing. The PLS can be factory programmed with a critical level set point so that whenever the set point is reached, the low side driver will close the circuit to allow a pump to turn on or open a valve. • Multiple Point Control – Fluid-Trac® PLS can be used for liquid level regulation to either keep a tank between two or three critical level set points or to activate two or three different external operations at each critical set point. Monitoring liquid levels to the factory programmable limit level set points allows for activation of pumps, valves and external alarms (audible, flasher, LED). For original equipment manufacturers, SSI engineering can customize the Fluid-Trac® PLS embedded software to provide the best solution for your unique application needs. Some custom options include the following: • Latching of Output Driver Circuit • Time Delays – When the level limit is tripped, the timer is started and the output is energized.
