The PPS71 PTS Geothermal Tools are designed for extreme subsurface conditions. The robust electronics combined with vacuum flask technology allow these products to perform at 350 °C (662 °F) continuously, for four hours. The PTS tool measures pressure, temperature, and flow profile and can be configured as either a memory tool or surface read out (SRO) tool. The measurements are done with a highly sensitive silicon-sapphire (piezo) transducer, an fast response resistance temperature detector (RTD) and the customer’s choice of either a continuous or fullbore spinner flowmeter. Both continuous and fullbore spinners are intended for quantitative use in flow streams with the spinners’ greatest quantitative application being injection profiling.
