Model P72 • Capacitance Probe, Flexible Cable, Parallel Ground Features Cable may be coiled for easy handling Easily installed in tall tanks May be installed in indoor tanks with low headroom PTFE insulation allows operation in conductive, or nonconductive liquids at high temperatures Corrosion resistant PTFE seals and jacket Suitable for high pressures and temperatures Description The Delta Controls Model P72 Capacitance Probe is commonly used in tanks made of reinforced plastics or metal tanks lined with rubber, glass, or plastic which do not contain the ground reference plane required by an RF admittance instrument. Model P72 should generally be used when the level change is less than ten feet, the tank diameter is greater than eight feet, or the measured liquid has a dielectric constant of less than 3.5 units. Low dielectric liquids include fuel oil, gasoline, benzene, and liquefied petroleum gases. P72 is also used in tanks with sizeable or nonlinear side walls, as well as when indoor tanks have limited headspace. Most applications require the optional bottom weight (option WT) to keep the cable taut.
