Flowmeter with pressure and temperature sensors, too

The Proline Prosonic Flow G flowmeter (photo) can be supplied with either of two different transmitters (photo): as a compact version (Proline 300), or as a remote version (Proline 500) with up to four inputs and outputs. These inputs and outputs provide flexibility, with the ability to output not only flow, but also pressure, temperature and numerous other process variables. This flowmeter measures both dry and wet gases with high precision (±0.5%), repeatability, and high reliability — even when process and ambient conditions fluctuate significantly. The meter operates at process temperatures up to 150°C (302°F) and pressures up to 100 bars (1,450 psi), and can be ordered with built-in pressure and temperature sensors. The input from these sensors can be combined with the measured sound velocity to calculate additional gas properties, which are often important for process control. Some examples are volume flow, corrected volume flow, mass flow, energy flow, calorific value, Wobbe index, gas type, molar mass, methane content (%) and density or viscosity. — Endress+Hauser, Greenwood, Ind.
