Ultrasonic Gas Flowmeter has Integrated Pressure and Temperature Sensors

The Proline Prosonic Flow G 300/500 flowmeter from Endress+Hauser is available 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. The flowmeter can measure both dry and wet gases with high precision (±0.5%), high repeatability, and high reliability—even when process and ambient conditions fluctuate significantly. Robust industrial design makes it possible to operate the flowmeters long term without maintenance, saving time, and money. The meter operates at process temperatures up to 150 °C (302 °F) and pressures up to 100 bar (1450 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, often important for process control. An optional “Extended Gas Analysis” function package is available for special applications and to meet process control requirements. Depending on the selected gas type (pure gases, gas mixtures, coal gas, natural gas, customer-specific gases, etc.), this function enables the calculation of additional parameters and process variables. 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. All wetted parts are stainless steel, and the flowmeter complies with NACE MR0175/MR0103. The meter’s ultrasound transducers are available in titanium Grade 2.
