The Prosonic Flow Clamp-On 91W by Endress+Hauser is an ultrasonic transit-time flowmeter designed for non-invasive, external measurement of water and wastewater systems. Ideal for applications in drinking water, process water, saltwater, deionized water, cooling, and heating circuits, it offers a cost-effective solution for flow monitoring without interrupting the process.
Key Features
- Non-Contact Measurement: Utilizes ultrasonic technology to measure flow from outside the pipe, eliminating the need for pipe penetration.
- Wide Pipe Compatibility: Suitable for pipe diameters ranging from DN 15 to DN 2000 (½" to 80").
- Temperature Range: Operates in medium temperatures from -20°C to +80°C (-4°F to +176°F).
- IP68 Protection: Ensures durability and reliability in various environmental conditions.
- Automatic Frequency Scan: Enhances measurement performance by automatically selecting the optimal frequency.
- Maintenance-Free Installation: Features a clamp-on design with corrosion-resistant materials, reducing maintenance needs.
- Heartbeat Technology: Provides continuous self-monitoring and diagnostics for proactive maintenance.
- Short Inlet Run Capability: Thanks to FlowDC technology, it allows installation in locations with short inlet runs.
- Web Server Interface: Enables remote configuration and monitoring via a web browser.
Applications
- Water and Wastewater Treatment: Monitoring flow in treatment plants and distribution networks.
- Industrial Water Systems: Measuring flow in cooling and heating circuits.
- Hydropower Plants: Assessing flow rates in water intake and discharge systems.
- Process Water Applications: Monitoring flow in various industrial processes.
System Components
- Sensor: Clamp-on ultrasonic sensor suitable for various pipe sizes.
- Transmitter: Prosonic Flow 91 transmitter with a 4-line display and touch control.
- Coupling Medium: DK9CM coupling medium for optimal signal transmission.
- Sensor Cable: DK9SS sensor cable set available in lengths from 15 to 90 feet.
Benefits
- Cost-Effective: Lower installation costs due to non-invasive measurement.
- Flexible Installation: Can be installed on existing piping without system shutdown.
- Enhanced Process Transparency: Provides real-time data and diagnostics for better process control.
- Long-Term Stability: Maintenance-free design ensures reliable long-term operation.
