ST – PT Insertion TURBINE Mass Flow Meter

ST PT INSERTION TURBINE MASS
FLOW METER

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.

Features

  • Volumetric or mass flow monitoring of most liquids, gases, and steam
  • Multivariable meter delivers mass flow, temperature, pressure, and density readings from a single installed device and reduces initial cost, installation cost and cost-of ownership over the lifetime of the instrument
  • Compensated mass flow reading of liquids, gases, and steam
  • Easy to install and commission–Hot tappable, process shut down not required for installation
  • Field configurable ranges, outputs and displays
  • 4-20mA loop–powered Mass Meter design saves on energy costs, HART protocol communications – Standard, Modbus, BACnet communications available
  • Insertion style mounting permits installation in any pipe 2” and greater
  • Pressure up to 1500 psig
