The ultrasonic flow meter for demanding applications in the oil and gas industry
Huge gas reserves continue to be discovered. The demand for natural gas as a source of fuel or energy is expected to continue to increase. Whether it's natural gas, process gas or gas blends, whether in the offshore or onshore sector: Endress-Hauser's new Prosonic Flow G is the ideal flow meter for demanding applications. The flow meter combines a tested and approved ultrasonic measurement technology with decades of experience in the chemical, oil and gas industries.
Benefits
- Ideal for raw and processed natural gas, coal gas, shale gas, process gas, gas mixtures as well as biogas and digestion gas
- Robust industrial design for process temperatures of up to 150 degrees Celsius (302 degrees Fahrenheit) and pressures of up to 100 bar (1450 psi)
- Powerful 24-hour process controls using offset pressure and temperature values, measured in real time
- Advanced gas analysis functions for calculating additional process variables as well as entering customer-specific gas and gas mixtures (with up to 8 components)
- Condensate-insensitive sensor for measuring wet or wet gases
- Precision measurement (±0.5%) high storage (>133:1)
Prosonic Flow G measures both dry and wet gases with high reliability. Combined with the extensive functionality of The Proline 300/500 transmitters, it opens up new opportunities for process control and monitoring. Prosonic Flow G guarantees accurate measured values with unmatched repeatability, even with varying ambient conditions and processes. With its robust industrial design, the device can be used over a long period without maintenance, saving the user time and money.
Optimal follow-up of the process through advanced gas analyses
Prosonic Flow G 300/500 can be equipped with additional advanced gas analysis features, e.g. for special applications or for increased process control needs. Depending on the type of gas selected (pure gas, gas mixture, natural gas, etc.), this function allows the calculation of additional parameters and process variables. Examples include volume flow, corrected volume flow, mass flow, energy flow, calorific value, Wobbe index, molar mass, methane content (%), density or viscosity.

Robust and industry-optimized
Prosonic Flow G offers high robustness. All wet parts are made of Grade 2 stainless steel and titanium and are NACE MR0175/MR0103 compliant. The entire sensor case is also made of corrosion-resistant stainless steel, so ProsonicFlow G is specially designed for difficult environmental conditions, especially in the offshore sector. Prosonic Flow G has been developed to meet CEI 61508 (SIL) and is suitable for security applications.

Heartbeat technology - for maximum operating security
Heartbeat technology, another strong point. Integrated into all Proline measuring devices, this verification feature allows for permanent self-diagnosis with maximum diagnostic coverage (>95%) as well as a traceable metrological check that is being processed. All of this reduces complexity and risk in the installation and increases its reliability and availability.
Transmitters for simple system integration
Different transmitters are available for the T-mass F and I sensors: Proline 300 (compact version) or Proline 500 (remote version) with up to four inputs and outputs. They allow simultaneous measurement of mass flow and energy flow, flow speed, gas temperature, and corrected density and volume flow. Access to all measurement and diagnostic data is possible at any time through digital transmission via HART or Modbus RS485, as well as via Wi-Fi or via inputs and outputs that can be combined at will.
