ST PT Insertion Turbine Mass Flow Meter
These multivariable flowmeters utilize three primary sensing elements – a turbine sensor, an RTD temperature sensor, and a solid-state pressure transducer – to measure the mass flow rate of gases, liquids and steam. Because the ST PT is able to measure all process variables within a single device it provides exceptional accuracy, simplifies system design and reduces installation costs. They are easily installed with flanged or Male NPT process connections in any pipe size of two-inches and greater. Optional retractor or “hot-tap” hardware simplifies maintenance operations. provides excellent rangeability and can measure very low flow rates with negligible permanent pressure drop. Additionally rotors are interchangeable, making this meter a good choice for installations with step changes in seasonal flow rates.
