Model P72

SKU: P72

Capacitance Probe, Flexible Cable, Paralell Ground Reference

The Delta Controls Model P72 is needed when a tank is very large or has nonlinear side walls such as does a horizontal cylinder or a sphere. It also is used where indoor tanks have only limited headspace above them. Most applications require the optional bottom weight to keep the cable taut. The P72 probe is essentially a P71 to which has been added a parallel ground reference cable. Many nonconductive liquids have low dielectric constant values. It is important that the rangeability tables be consulted and followed to insure adequate intrinsic gain of the probe. A parallel ground cable will also usually solve rangeability problems in large tanks of low dielectric liquids. The P72 should generally be used when the level change is less than ten (10) feet, where the tank diameter is greater than eight (8) feet, or when the measured liquid has a low dielectric constant (less than 3.5 units). Low dielectric liquids include fuel oil, gasoline, benzene, and liquefied petroleum gasses. The P72, with parallel ground cable, is also required when the tank has a nonlinear ground reference side wall, such as is found in a horizontal cylindrical tank or an LPG sphere. This probe is not suitable for service in powders or solids.
