Vortex flowmeter for gas, steam and liquid.
- Insensitive to vibration, temperature shocks, dirty media and water hammer
- Permanent self-monitoring and diagnosis
- HART®, PROFIBUS PA and FOUNDATION Fieldbus compatible
Prowirl 72 has universal appeal – its plain text pushbutton operation allows swift, simple commissioning and its wide temperature range means it is suitable for most applications. Proven in thousands of applications worldwide, Prowirl’s unique differential switched capacitance (DSC) sensor is totally reliable, even in harsh environments (ATEX certified).
- Compact, remote or reduced bore versions
- Dualsens version with two sensors and electronics (for redundancy)
- Hastelloy C-22 version
The sensor of a vortex flowmeter has a major influence on the performance, robustness and reliability of the whole measuring system. Prowirl 72 uses Endress+Hauser’s proven and patented capacitive measuring technology, with more than 100,000 measuring points installed worldwide. Due to its internal mechanical balance, the DSC sensor (Differential Switched Capacitance), reads only the pressure pulses caused by the vortices and stays immune to any influence from mechanical pipeline vibrations. The DSC sensor measures low flow rates at low fluid density even when pipeline vibrations are present. Therefore, Prowirl 72 keeps its wide turndown ratio even under rough operating conditions. Vibrations of at least 1g at frequencies up to 500Hz in all axes do not affect the flow measurement.
Applications
- Liquid nitrogen
