摘要： A dedicated liquid level detection method having a sensor positioned into the casing of a groundwater well. The detector is in the form of an elongated thin film sensor tape that extends along the fill length of the well casing which detects the level, thickness and volume of both groundwater and any light or dense non-aqueous phase liquid that may be present. This is accomplished through the use of a conductive and hydrostatic resistive circuit measuring the level of liquids in a groundwater well at one hundredths of foot resolution or greater. Once the elongated sensor is installed, liquid levels can be gauged from the surface. The data is stored using a battery operated hand held digital display temporarily connected at the top well section casing. Since a sensor probe is not lowered into the well, cross contamination between wells is eliminated.

摘要： A dedicated liquid level detection method having a sensor positioned into the casing of a groundwater well. The detector is in the form of an elongated thin film sensor tape that extends along the full length of the well casing which detects the level, thickness and volume of both groundwater and any light or dense non-aqueous phase liquid that may be present.This is accomplished through the use of a conductive and hydrostatic resistive circuit measuring the level of liquids in a groundwater well at one hundredths of foot resolution or greater.

The data is stored using a battery operated hand held digital display temporarily connected at the top well section casing. Since a sensor probe is not lowered into the well, cross contamination between wells is eliminated.

摘要： A capacitive liquid level sensor material, which includes a first thin, flexible, elongated insulating substrate of indeterminate length having a continuous sensing capacitor printed thereon. The sensing capacitor has a repeating interdigitated capacitive pattern formed by two separate electrodes printed on the substrate. There is a second thin, flexible, elongated insulating substrate of indeterminate length joined to the first substrate to electrically isolate the sensing capacitor, and the electrodes coplanar. The second substrate has a graphic ink pattern printed thereon. The joined first and second substrates are arranged to be wound up into a roll of at least several turns. The sensor material is then cut to length and terminated with a crimp type connector to produce a sensor of the desired length.

摘要： First and second elongated flexible insulated substrates have patterns of resistive liquid level sensor sections along the substrate lengths, each pattern comprising printable resistive ink of the same resistivity (ohms-squared), wherein the patterns can be simultaneously printed upon each substrate to save manufacturing costs. The substrates can be separated by an elongated spacer that couples longitudinal edges of the facing substrates together with an appropriate adhesive. Alternatively, the facing substrates can be folded along a central fold line to form a first longitudinal edge and adhesively joined along a second longitudinal edge opposite the first longitudinal edge. The flexibility of the substrates enables the low manufacturing cost liquid level sensors to be positioned in for example in a highly irregularly shaped vehicle fuel tank. Also, sections of varying lengths to be cut from the rolls on demand by users to form customized lengths of liquid level sensors for numerous applications.

摘要： An outer passive reference resistor loop is printed along the length of an elongated substrate along with an inner active liquid level sensing resistor loop, whereby the reference resistor loop is exposed to exactly the same varying temperature conditions as the active level sensing resistor loop (e.g. in half air/half water), thereby providing superior temperature compensation. An upper plastic substrate carries a elongated conductive strip that is positioned over the first and second legs of the inner resistor loop but not over the legs of the outer resistor loop and wherein the first and second insulated substrates are coupled together providing separation of the substrates in the absence of hydrostatic pressure, and for causing conductive bridging contact by the elongated strip of an electrically conductive material contacting the first and second legs of the inner resistive elongated loop in the presence of hydrostatic pressure. Printed inks produce the resistive loops.
